A STUDY OF SOME BIOACTIVITIES AND ISOLATION OF PURE ORGANIC COMPOUNDS FROM THE BARK OF DOCYNIA INDICA (WALL.) DECNE (PIN-SEIN)
Abstract
- In the research work, the bark of Docynia indica (Wall.) Decne (Pin-Sein) was collected from Pang Wa Village, Loi Mwe Township, Shan State. Phytochemical constituents present in the bark of PinSein were investigated according to the general methods. Two kinds of nutritional values (moisture and ash) of Pin-Sein bark were determined by oven dry method and AOAC method. In addition, the elemental contents in this sample were determined by EDXRF. The antimicrobial activities of the various crude extracts were tested by agar well diffusion method on six selected microorganisms (Bacillus subtilis, Staphylococcus aureus, Salmonella typhi, Bacillus pumilus, Candida albicans and Escherichia coli). Moreover, antioxidant activity of crude extract of Pin-Sein bark was measured by DPPH free radical scavenging assay method. The pure organic compounds, TMK-1 and TMK-2 were isolated from the bark of Pin-Sein by thin layer and column chromatographic techniques. Finally, these isolated compounds were identified by phytochemical tests and their respective melting point. The functional groups of pure organic compounds were identified by FT IR spectral data.
