Abstract Postharvest loss of fruits is a critical problem due of rapid deterioration during handling,
transportation and warehousing. Edible coating over fruits is utilised to boost their quality and shelf
life. The effects of leaf extracts of Psidium guajava and Aloe vera gel on the elongation of the shelf
life of orange fruits were evaluated. Orange fruits were treated with Guava leaf powder and A. vera
gel to assess their effectiveness in extending their shelf life and quality in storage. Weight loss,
firmness, post-harvest decay, marketability and shelf life of uncoated and coated samples were
evaluated all through the period of this study. Fungi were also isolated from deteriorating samples.
A. vera was able to preserve the orange samples for 21 days; P. guajava preserved them for 17
days while the untreated fruit samples stayed for 14 days. Three fungi viz: Botryodiplodia
theobromae, Fusarium oxysporum and Rhizopus stolonifer were isolated from the decomposing
orange fruits. The result shows that orange fruits coated with A. vera gel and guava leaf powder is
effective in extending the shelf-life of orange fruits when compared to untreated fruit (control) in the
following order: A. vera>P. guajava > control. The findings from this study indicate that plant
extracts could be employed to prolong the shelf life and improve quality of orange fruits

Abstract This study investigated the mineral composition and antioxidant potentials of the leaves of Monkey’s Potato (Solenostemon monostachyus (P. Beauv.)
Briq.) The leaves of S. monostachyus used in this study were collected from the Biological garden at College of Education, Warri, Delta State. Standard
methods were employed to determine the composition of minerals and antioxidant capacity of S. monostachyus. The results from the mineral analysis
revealed that calcium had the highest composition (2.64 ± 0.01 mg/kg) followed by manganese (1.74 ± 0.00 mg/kg) and zinc (1.02 ± 0.00 mg/kg). While
the composition of iron, copper, nickel and lead were 0.83 ± 0.01 mg/kg, 0.64 ± 0.01 mg/kg, 0.04 ± 0.01 mg/kg and 0.02 ± 0.00 mg/kg respectively. Results
from the antioxidant analysis (DPPH Assay) revealed a significant difference in the radical scavenging activity of Solenostemon monostachyus and
Ascorbic acid, with Solenostemon monostachyus having a significantly higher DPPH radical scavenging activity with an IC50 value of 0.25ug/ml than
Ascorbic acid with an IC50 value of 0.03ug/ml. The total antioxidant capacity of Solenostemon monostachyus was 0.6 ± 0.01 (AAE/g) indicative of strong
antioxidant activity. These minerals and antioxidant properties may account for the various health benefits of Solenostemon monostachyus. Based on the
result obtained, it is therefore recommended that S. monostachyus should be cultivated for its various nutritional and antioxidant potentials rather than
being treated as a weed.

Abstract The study was on evaluation of the variations in some minerals in the leaf,
stem bark and root of Jatropha curcas. Standard analytical procedures
were used in the study. Results from the analysis revealed that magnesium
was present in the highest amount in the leaf (389 ± 0.33 mg/kg) followed
by root (307.03 ± 0.79 mg/kg) and stem bark (203.75 ± 0.04 mg/kg). This
was followed by calcium which was present in highest amount in the root
(99.23 ± 0.56 mg/kg) followed by stem bark (82.57 ± 0.76 mg/kg) and leaf
(80 ± 0.82 mg/kg). The concentration of iron was highest in the leaf (13.13
± 0.26 mg/kg) followed by the root with a mean value of 12.47 ± 0.45
mg/kg, and lastly the stem bark (10.33 ± 0.69 mg/kg). The contents of
phosphorus in leaf and stem bark were 10.46 ± 0.12 mg/kg and 10. 14 ±
0.22 mg/kg respectively, while the root content was low with a value of
4.49 ± 0.03 mg/kg. There was however, no significant difference in the
mean mineral composition of the various parts of J. curcas. The findings
from this study justifies the use of this plant in traditional medicine
practice and reveals its potential use as a nutritional supplement to combat
various mineral deficiency related diseases. Increased domestication of this
plant is recommended to ensure conservation for future use.

Abstract The study evaluated seven varieties of cowpea, Vigna unguiculata (L.) Walp.,
namely: Ife Brown, IT98K-128-3 , IT98K-506-1, IT93K-452-1 and IT95K-1072-
57, IT06K-149-1, and IT06K136 that were laid out in a complete randomized block design (CRBD) with seven replications for the production of root nodules. It comprised of two field trials (during the wet season and the dry season of 2021 cropping season respectively) that were carried out at an experimental garden in Agbor, Delta State. The rainy season plants were rain-fed while the dry season experiment was watered manually when the rainy season finally ended. The study established that nodulation was a primary determinant of the agronomic and yield characteristics of legumes. Consequently, genotypes with large number of nodules per plant recorded more peduncles, pods per plant, longer pod lengths and consequently gave better grain yield and were recommended for inclusion in further cowpea hybridization programmes in the region.

Abstract Ethnobotanical Investigation has revealed that the roots of Thevetia peruviana and leaves of Parquetina nigres-cens are being used to treat bacterial diseases. Phytochemical screening revealed the presence of alkaloids and terpenoids in both species. Agar well diffusion method was employed in the sensitivity test of the studied eth-nobotanicals. Different concentrations (50, 100, 200 and 300mg/ml) of extracts of T. peruviana roots and P. ni-grescens leaf extracts were employed against E. coli, Pseudomonas aeruginosa, Salmonella typhi, Staphylococcus aureus and Streptococcus mutans. All the organisms showed highest and lowest levels of inhibitions at 300mg/ml and 50mg/ml respectively. Leaf extract of P. nigrescens showed relatively more activities than the root extract of T. peruviana against the tested organisms. The Minimum Inhibitory concentration of both ex-tracts also showed considerable activity at (50,100 and 200) mg/ml while the growth of the microorganisms was unrestrained at 25mg/ml.

Abstract Ethnobotanical investigation revealed commonly used medicinal plants (Detarium microcarpum, Ficus sur, Jatropha gossypifolia, Khaya seneglensis, Mangifera indica, Parquetina nigrescens, Sorghum bicolor, Talinum triangulare, Tamarindus indica and
Theobroma cacao) for treating anaemia in Kwara State, Nigeria. Plant parts used were subjected to phytochemical screening and proximate analysis using standard methods. Three preparation methods were revealed to be used commonly; (i)
decoctions and Infusions (33.33 %), (ii) powdery form (22.22 %) and (iii) Concoction (11.11 %). Our study reported the use-value (%) of three plant habits (tree, 70 %; herbs, 20 %; and shrubs, 10 %) and of the plant-parts (leaves; 50% and bark; 50 %).
Phytochemical screening recorded Alkaloids (D. microcarpum [486.67 ± 6.01] and J. gossypifolia [93.33 ± 1.67]), Anthraquinones [J. gossypifolia (93.33 ± 1.67); K. senegalensis (75.00 ± 2.89) and S. bicolor (6.67 ± 1.67)], Cardiac-glycosides[J. gossypifolia (78.33 ± 4.41) and S. bicolor (13.33 ± 1.67)], Flavonoids [Tamarindus indica (850.00 ± 7.64) and P. nigrescens (86.67 ± 4.41)], Phenolics [M. indica (75.43 ± 0.88) and T. cacao (9.40±0.58)] Saponins(F. sur [1258.33 ± 11.7] and M. indica [155.00 ± 10.41]), Tannins (Sorghum bicolor [1865.00 ± 7.64] and T. cacao [326.67 ± 7.26)], and Terpenoids [T. triangulare (1260.0 ± 7.64) and S. bicolor (35.00 ± 0.00)] in varying concentrations. Our proximate analysis detected ash, crude fibre, carbohydrate, moisture, protein, and ether extract content in different concentrations. In addition, micro-nutrient was significantly high (P?0.05) in M. indica (Calcium
[256.67±4.41] and Magnesium [90.00 ± 2.89], J. gossypifolia (Zinc, 0.53 ± 0.33) and T. triangulare (Iron, 16.37±0.88). From the results obtained it is evident that the studied plants contain several secondary metabolites which may have contributed to
their anti-anaemic properties thereby, making them good sources of nutraceuticals for the management and treatment of Anaemia. Further studies are therefore recommended to determine the exact agent responsible for this activity in the plants
and a possible mechanism of action.

Abstract Ethnopharmacological relevance: Malaria is one of the most severe public health problems worldwide. It is a leading cause of death and disease in many developing countries, where young children and pregnant women are the groups most affected.Spread of multidrug-resistant strains of Plasmodium and the adverse side effects of the existing anti-malarial drugs have necessitated the search for novel,well tolerated and more efficient antimalarial drugs.This ethnomedicinal study surveyed the different types of medicinal plants used for the treatment of malaria in Southern Nigeria with the intent of identifying plants that are traditionally employed in the treatment of malaria across geopolitical boundaries. Materials and methods: Data were collected from 79 respondents composed of 50 traditional herbsellers and 29 herbal practitioners using a semi-structured questionnaire. Data was analyzed using frequency and percentages. Results: Of the79 respondents interviewed, 24% were males while76% were females.A total of 156 species belonging to 60 families were reported being used to treat malaria in the study area.Fabaceae was the most represented family having fourteen (14) plant species.Of the plants identified during the survey, Azadirachta indica was the species of highest relative frequency of citation (RFC – 1.0).The dominant plant parts used in the preparation of remedies were leaves (50.50%) and Decoction was the main method of preparation. Analysis of regional plant occurrence revealed that South-Western Nigeria represented the region with the highest plant occurrence (60.7%) followed by South–South (24%) and South–East (15.3%).Regional occurrence of plants used in the treatment of malaria in Southern Nigeria is reported here for the first time. Conclusion: This study has documented a great diversity of plants used in the treatment of malaria in Southern Nigeria. Extracts prepared strictly according to the practitioners' recipes should therefore be screened for antiplasmodial activity and toxicity by in vitro and in vivo standard tests to justify their local usage. These studies might lead to the isolation and possible identification of potentially active compounds, which may be regarded as future promising phytomedicines in the treatment of malaria.Conservation of these plant species is also recommended to ensure their continuous availability for future use.

Abstract Malaria, an infection caused by Plasnmodium, is a disease transmitted to humans by the female
anopheles mosquito. It remains a major cause of death throughout the world especially in subSaharan Africa. The useof herbs for the treatment of malaria is a folk medicinal procedure in Nigeria
but the herbs used and the quantity vary from one region to another. It has also been revealed that of
all the plant parts used in the treatment of malaria, the leaf has the highest frequency of usage. This
study was designed to investigate the variation in the carotenoid content of frequently used medicinal
plants in the treatment of malaria in South-Western Nigeria. Quantitative phytochemical analysis
showed that carotenoids were present in the different plant parts in various concentrations. However,
the carotenoid content was significantly higher (P<0.05) in the leaves of the different plants. Of all
the plants analyzed, carotenoid content was significantly higher (P<0.05) in Morinda lucida leaf
(207.742.Smg/kg GAE) and almost absent in the roots of Chromolaena odorata and Chrysophyllum
albidum (having 1.0+0.0 mg/kg GAE, respectively). These results show that carotenoids occur in the
different plant parts in varied concentrations. However, the high composition of carotenoids observed
in theleaves of the various plantsanalyzed is suggestive of their high frequency of usage in traditional
medicine for the treatment of malaria.

Abstract Malaria is endemic to Africa in which Nigeria is the largest country. Medicinal plants are harvested widely in parts or as a whole due to the curative effects derived from their phytochemicals. It is common knowledge that just about
10% of the total plants have their phytochemicals known hence the desire to investigate the various phytochemicals present in the plant parts. Variation in the phytochemicals present in the leaf, root and stem bark of some frequently used Nigerian medicinal plants - Adansonia digitata, Alstonia boonei, Anacardium occidentalis, Azadirachta indica, Carica papaya, Chromolaena odorata, Chrysophyllum albidum and Citrus aurantifolia in the treatment of malaria were therefore investigated. Quantitative phytochemical analysis revealed the presence of tannins, alkaloids, flavonoids, terpenoids, saponins and phenolic acids in various concentrations as there were significant differences (p<0.05) between these phytochemicals and their plant parts. The presence of varied active ingredients in the different parts of these plants explains their diverse use in the treatment of different disease conditions. The research into the isolation and identification of these active ingredients in the different plant parts will help to authenticate the diverse claims of herbal practitioners on the use of plants and their parts in the cure of several diseases.

Abstract AIM: The Antioxidant activities of the leaf, root and stem bark of 16 selected Nigerian medicinal plants frequently used in the treatment
of malaria in South-Western Nigeria were investigated.
METHOD: The radical scavenging activities of the plant extracts against 2,2 Diphenyl -1-picryl hydrazyl, were determined by UV
spectrophotometry at 570nm.
RESULTS: Quantitative analysis showed that the different plant parts demonstrated antioxidant activity in various degrees. However,
DPPH radical scavenging activity was significantly highest (P<0.05) in the leaves of the different plants analyzed. Of the various plants
analyzed, Rauwolfia vomitoria leaf had the highest radical scavenging activity with percentage inhibition of 2.2 diphenyl -1-
picrylhydrazyl (DPPH) radical of 82.8±0.2% followed by that of Vernonia amygdalina having 82.6±0.2% inhibition. The stem bark of
Vernonia amygdalina demonstrated the least antioxidant activity with only 2.9±0.1% inhibition of the DPPH radical.
CONCLUSION: The present work revealed that extracts of these plant parts possess antioxidant activity demonstrated in their various
percentage inhibitions of the DPPH radical. However, the high antioxidant activity observed in the plant leaves confirms their frequency
of usage in traditional medicine for the treatment of malaria

Abstract The integration of ICT in biology teaching has profound effect on students’ achievement since learning is enhanced through audio and visual aids among others. Because of the paucity of computers in schools, it is likely that many teachers have low self-efficacy beliefs on the use of ICT for secondary school biology teaching. The Computer Self-Efficacy instrument was used as a tool to investigate the self-efficacy belief on the use of ICT for secondary school biology teaching by teachers. This instrument was administered on 200 randomly selected secondary school biology teachers in Warri Municipality, Nigeria, and its suburbs. A benchmark of 2.50 was used to make decisions relative to the group mean values obtained for answering the research question posed in the study. The results indicated that the secondary school biology teachers have positive self-efficacy belief in seven (7) of the ten (10) items of the research instrument. Implications of the results were discussed and suggestions were put forward about the direction for future studies.

Abstract Investigation into the effects of different concentrations of salinity at OmM, 90mM,
180mM and 360mM on the growth and development of maize (Zea mays L.) variety SUWAN=1-SR 063802 was carried out over a period of six weeks of treatment after the establishment of the crop for three weeks in the screen house in a randomized block
design. Salinity effect on maize is concentration dependent. There was no significant difference (p>0.05) jbetween the control (OmM) and 90mM treated plants (TP) in terms of leaf number, leaf*area, stem girth and senescence, but the control was significantly different (p<0.05) from the 180mM and 360mM TP in growth parameters such as leaf
number, leaf area, plant height, senescence and stem girth. Plants subjected to 180mM salinity showed significant leaf chlorosis from three weeks after treatment (3WAT) while those of 360mM NaCl treatment had started to senesce and complete death was recorded 6WAT. In spite of the fact that flowering was first observed in the control plants followed by those subjected to 90mM NaCl treatment, there was faster rate of its development in the 90mM TP; an indication that moderate level of salinity promotes
flower development in maize, but high salinity causes reduction in leaf number, plant height, leaf area, fresh weight, dry weight and an increase rate of senescence.

Abstract Malaria prevalence is one of the life-threatening diseases responsible for more deaths around the world than any other parasitic disease. Due to the outbreak of strains that show resistance to the current synthetic anti-malarial arsenal, a large focus has been directed to structure based drug designing. The present study investigated the anti-malarial active constituents present in an ethanolic extracted polyherbal formulation (Agbo-iba PMII) comprising Sixteen (16) plants using GC-MS analysis and molecular docking studies of the identified compounds to determine the potential of the polyherbal formulation to treat malaria. The results revealed 42 phytochemical constituents derived from the GC-MS analysis. However, the result from the molecular docking studies done using Autodock/Vina show that 1,3-Diphenyl-2-azafluorene with a binding affinity of -10.2 Kcal/mol found only in Azadirachta indica holds more promising lead target formation against malaria. From the results obtained, it can be concluded that1,3-Diphenyl-2-azafluorene acts against malaria by blocking Methionyl-tRNA synthetase (MRS) and can further be developed into a potent drug for malaria.

Abstract Tectona grandis Linn (commonly known as teak) is a large, deciduous tree reaching over 30m in height known for decades for its timber value. This plant's wood is renowned for its extreme durability, dimensional stability, and hardness, which also resist decay even when unprotected by paints and preservatives. The present study analyzed the phytochemical & pharmacological potential of the methanolic extracts from leaf, stem-bark, and roots of Tectona grandis. Tectona grandis extracts revealed the presence of six phytochemicals with Saponins present in all extracts. Antibacterial activity of all
extracts from Tectona grandis was checked against Escherichia coli, Pseudomonas aeruginosa, Salmonella typhi, Streptococcus mutans, and Staphylococcus aureus by disc diffusion assay. The methanol extract of stem bark showed inhibition of the growth of Escherichia coli and Staphylococcus aureus. Antifungal activity of all extracts from Tectona grandis was checked against Aspergillus flavus, Asperigillus fumigatus, and Candida albicans. The methanol extract of leaves showed inhibition of the growth of Candida albicans. The study results provide a scientific basis for the use of this plant extract in future development as antibacterial and antifungal agents.
