Three novel bisabolane-type sesquiterpenoids, phyllaemblic acids B (1) and
C (2) and phyllaemblicin D (3), together with two new phenolic glycosides,
2-carboxylmethylphenol 1-O-beta -D-glucopyranoside (4) and 2,6-dimethoxy-4-
(2-hydroxyethyl)phenol 1-O-beta -D-glucopyranoside (5), were isolated from
the roots of Phyllanthus emblica. The structures of 1-5 were established by
spectral and chemical methods. The absolute stereochemistry of 1 and 2 was
determined by applying the PGME method.
