Plants serve as a vast source for varied phytoconstituents exhibiting varied pharmacological properties. It is one of the richest plant sources of Vitamins A, B (Ramachandran, 1980; Odee, 1998; Jahn et al, 1986; Palada et al, 1995; Gilani et al, 1994) Vit. C, D, E and K. The vital minerals present in Moringa include Calcium, Copper, Iron, Potassium, Magnesium, Manganese and Zinc. Leaves, flowers, and pods are common vegetables in the Asian diet. The chemical constituents of the Hexane and Ethanol extract of Moringa oleifera Lam. Flowers were investigated. Different chemical constituents were identified in the extract; unsaturated fatty acids, especially oleic acid, alkaloids, steroids, flavonoids, tannins, saponins, carbohydrates, and minerals are present in the extract. This work aims to identify the main constituents from Moringa oleifera Lam. Flower extract.

The aim of this study was to evaluate the antimicrobial potential and phytochemical screening of Moringa oleifera leave extract as folkloric medicinal alternative. The phytochemical screening result revealed the presence of Alkanoids, Saponins, Fats & oil, Terpenoids and Tanin in all the solvents used for the study. Agar-disc diffusion method were used to determine the antimicrobial activities of the Moringa oleifera extracts on microorganisms. Maximum activities of inhibition were recorded on Ethyl acetate (50mg/ml) against Pseudomonas auroginusa, moderarate activities against Escherichia coli. Likewise 50mg/ml of Haxane extract show weak activities on Pseudomonas aeruginosa, moderate in both Staphalococcus aureus and Escherichia coli. Whereas 50mg/ml of Methanol show moderate activity on Pseudomonas aeruginosa, Staphalococcus aureus and weak activities on Escherichia coli respectively. The research revealed that Moringa oleifera bioactive components would be a safer alternative for curative and preventive emerging folkloric medicinal plant for treatment of bacterial ailments in Maiduguri, Borno state, Nigeria.

The effect of three different extraction methods, namely supercritical CO2, soxhlet and solvent methods on the yield, efficiency, physico-chemical properties, nutritional, anti-nutritional composition, antimicrobial and antioxidant activities of moringa (Moringa oleifera Lam.) seed kernel oil was investigated in this study. Oil extraction for SC-CO2 were 37.76 g/100g and 98.43%, observed to be higher than those of soxhlet extraction (29.12 g/100g and 76.29%), and significantly lower than solvent extraction (22.12 g/100g and 57.99%). The physico-chemical composition of the oils showed considerable variation among the extraction methods. The SC-CO2 extracted oil was found to be of superior quality, showing negligible thermal degradation and exhibited significantly (p<0.01) higher nutritional and antioxidant activity and lower anti-nutritional composition than the soxhlet and solvent extracted oils. Oils produced by SC-CO2 and soxhlet extraction methods had antimicrobial activities higher than solvent extracted oil. SCCO2 extracted oil was found to have maximum number of bioactive compounds (14 compounds) followed by solvent (8 compounds) and soxhlet (4 compounds) extracted oil. The results of the study demonstrated that SC-CO2 would be a promising process for the extraction of moringa seed kernel oil of premium quality.

The present study was carried out to determine the possible LC-MS and anti-microbial activity of plant extracts prepared from Muntingia calabura and phytochemical screening was demonstrated. The extracts from the plant parts like leaf were prepared in different solvents like petroleum ether, chloroform and ethanol. The highest antimicrobial potentials were observed for the ethanolic extracts against (Bacillus subtilis, Staphylococcus aureus, Klebsiella pneumoniae, Pseudomonas aeruginosa, Candida albicans) Its efficacy was comparable to the standard drug, amikacin. Significant amount of tannins, alkaloids, steroids and flavonoids were found. The present study provides evidence that solvent extract of M. calabura contains medicinally important bioactive compounds and this justifies the use of plant species as traditional medicine for treatment of various diseases. Likewise, the leaf extract of Muntingia calabura showed more zone of inhibition with fungus Candida albicans. This shows its antiseptic nature which might have been induced because of the components present.
