Abstract: Objective To study the chemical constituents from the roots of Phyllanthus emblica. Methods Compounds were isolated by various column chromatographies and elucidated by spectral analyses such as MS, IR, and NMR. Results Seven compounds were isolated in the 95% ethanol extract from the roots of P. emblica and their structures were identified as 3, 20-dioxo-dinorfriedelane (1), lupeol (2), β-sitosterol (3), stigmasterol (4), daucosterol (5), 4-O-methylellagic acid-3′-α-rhamnoside (6), and phyllaemblic acid (7). Conclusion Compound 1 is a new compound named phyllaemblicone A and compounds 2—6 are first isolated from the roots of P. emblica.
