"Determination of Phytochemical Constituents, Antimicrobial Activity and Isolation of Secondary Metabolite Compounds from the Stem Barks of Putranjiva roxburghii Wall. (Badi-byu)" Hein Wai Yan Htay Arnt Win Aye Mon Thida Nyo Yi Yi Myint "In this research, one of Myanmar indigenous medicinal plant Putranjiva roxburghii , popularly known as Badi-byu, was selected for chemical investigation. Firstly, the phytochemical screenings of selected sample were carried out. Moreover, the antimicrobial activities of the sample were determined by Ager-well diffusion method on seven tested organisms with various solvent extracts. Ethyl acetate extract responds high activity on all tested organisms. Hence, it was selected for detailed chemical analysis. Two pure compounds (HWYH-1 and HWYH-2) were isolated from ethylacetate extract of sample by using Thin Layer and Column Chromatographic separation methods. The Fourier Transform Infrared Spectroscopy (FT IR) spectra of isolated compounds (1 and 2) were studied and the prominent functional groups containing in these compounds were assigned." 2022-08-12 https://meral.edu.mm/records/8409
