Abstract
Three ester glycosides, named phyllaemblicins A (3), B (4), and C (5), and a methyl ester (2), of a highly oxygenated norbisabolane, phyllaemblic acid (1), were isolated from the roots of Phyllanthus emblica, along with 15 tannins and related compounds. The structures of 2-5 were established by spectral and chemical methods.
