Qualitative Phytochemical Analysis and Microbial Inhibitory Activities of Pacific Rain Tree (Samanea saman (Jacq.) Merr.) Pods

James Kennard Sanz Jacob, Eden S. David

Abstract


Background: Crop diseases and human health are always at stake and the emerging problem on the use of synthetic anti-pathogens and medicine is one of the most difficult to combat. The first step towards determining such capabilities among plants is to determine their phytochemicals.

Methods: Eight preliminary phytochemical tests was done on Samanea saman which includes, test for alkaloids saponins, flavonoids, tannins, glycosides, steroids, terpenoids and resins. Powdered pods were subjected to ethanol and aqueous extraction. Extracts were also tested for its antifungal and anti-microbial properties against Fusarium oxysporum, E. coli and S. aureus,respectively.

Results: Out of the eight phytochemical tests done, seven (7) were found to be present both on the ethanol and aqueous extracts namely, alkaloids, saponins, tannins, glycosides, steroids, terpenoids and resins. However, flavonoids is absent. The statistical results exhibited that there is a significant difference on the inhibitory effects against in-vitro bioassay of Fusarium oxysporumwhich is known to cause crop wilts and the two bacterial pathogens E. coli and S. aureus.

Conclusions: The presence of such phytochemicals in Samanea saman pods revealed that it can be a basis of new, natural and non-synthetic treatments. This finding suggests that its pods can be used as antibacterial and antifungal source.
