PHYTOCHEMICAL AND ANTIMICROBIAL INVESTIGATION ON LEAVES OF AVERRHOA BILIMBI L.
Abstract
- Averrhoa bilimbi L. is small tree, belongs to the family Oxalidaceae. It is locally known as Tayoke-zaung-yar. The plant was collected from Hinthada University Campus. The vegetative and reproductive parts of the fresh specimens were identified with the help of available literatures. In morphological study, the plant is small tree. The leaves are unipinnately compound and imparipinnate. The inflorescences are cauliflorous, arising in fascicles from main stem and thicker branches. The flowers are dark red-purple and hypogynous. Stamens 5+5, free and unequal. Ovary (5), axile placentation and stigma 5 fid. The fruits are berry fleshy with 5 blunt longitudinal ridges. The seeds are flattened disc like, smooth and white. The presence of alkaloid, glycoside, phenolic compound, flavonoid, steroid, terpenoid, tannin, saponin, -amino acid, protein, reducing sugar, starch and carbohydrate were found in phytochemical investigation. According to physicochemical properties, the powdered leaves were most soluble in methanol and least soluble in chloroform. The nutrient contents of powdered leaves were examined by using David Pearson and Kjeldahl method. The presence of protein, moisture, ash, fat, fiber and carbohydrate were found in the examination. Antimicrobial activities of various crude extracts were carried out by using paper disc diffusion assay with six test organisms. Chloroform and ethyl acetate extracts indicated more effective against the test organisms. Methanol and ethanol extracts showed moderate antimicrobial activity. These results showed that Averrhoa bilimbi L. leaves are rich in many active constituents, nutrients and antimicrobial properties and has potential to be used as medicinal application.
