K. Yoshikawa et al., PHENYLPROPANOIDS AND OTHER SECONDARY METABOLITES FROM FRESH FRUITS OFPICRASMA QUASSIOIDES, Phytochemistry, 40(1), 1995, pp. 253-256
Four new constituents; two benzofuran glucosides (picraquassiosides A
and B), a neolignan (picraquassioside C) and a phenol (picraquassiosid
e D) were isolated from fresh fruits of Picrasma quassioides, together
with seven known compounds. The structures of the new compounds were
elucidated as 6-hydroxy-4-methoxy-5-benzofuranpropionic acid 6-O-beta-
D-glucopyranoside, 6-hydroxy-4,7-dimethoxy-5-benzofuranpropionic acid
6-O-beta-D-glucopyranoside, lucopyranosyl-4'-hydroxy-3',5'-dimethoxyph
enyl-2(2 '',6 '' dimethoxy-4 ''-[1-(E) propen-3-ol-phenoxy)-propan-1,3
-diol(threo), and methylphloroglucinol beta-D-glucopyranoside by spect
roscopic means.
