In vitro Antioxidant, Antimicrobial and Phytochemical studies on Soymida febrifuga bark extract
Natural plant products are the source of the most active ingredients of the medicine. The present investigation is on phytochemical analysis and in vitro antimicrobial activities of the crude methanolic bark extract and ethyl acetate extract of Soymida febrifuga were tested for a wide variety of pathogenic bacteria and fungus. The phytochemical screening of the bark extracts revealed the presence of carbohydrates, tannins, glycosides, phenols, flavonoids, diterpenes, and steroids. Crude extracts of Soymida febrifuga show mild to moderate activities for most of the tested bacteria and almost no effect on tested fungal species. In vitro antioxidant activity of methanol extracts of Soymida febrifuga bark produce a dose dependent inhibition of free radical 2,2-diphenly-1-picrylhydrzyl(DPPH) reagent. The presence of Vitamin C (Ascorbic acid) from methanolic bark extract of Soymida febrifuga was estimated by 2,6-Dichlorophenolindophenol (2,6-DCPIP) method.
