ABSTRACT: Phyllanthus
emblica L. belonging to the family Euphorbiaceae is a common medicinal plant in
Bangladesh. In order to evaluate the phytoconstituents and bioactivity of
various parts of P. emblica, both the wild type (i.e.,
small) and cultivated (i.e., big) fruits were
collected from the local market of Bangladesh and six ethanolic extracts were
prepared from various parts of the collected fruits for this current study. A
comparative analysis of the phytochemical compositions and various
bioactivities especially antibacterial, antifungal, and antioxidant activity of
the six ethanolic extracts were accomplished. The qualitative phytochemical
analysis of plant extracts revealed the presence of large amounts of proteins,
carbohydrates, phenolic compounds, glycosides, alkaloids, coumarins,
flavonoids, tannins, saponins and resins etc. The maximum antioxidant activity
was observed for wild type P.
emblica seed
extracts and the minimum activity was observed for cultivated flesh extracts.
Moreover, among the samples the wild type P.
emblica extracts
have excellent amount of total phenol contents and the highest free radical
scavenging activity. It is also found that P.
emblica samples were active against both gram-positive (i.e., B. subtilis) and gram-negative (i.e., E. coli, and S.
typhi) bacteria.
The highest antibacterial activity was achieved in the wild type P. emblica seed
extracts against both pathogenic (S. typhi) and non-pathogenic
bacterial strains (E. coli, and B.
subtilis). These samples showed almost no activity against Fusarium sp. fungus.
