Three new glycosides from Sinopodophyllum emodi (Wall.) Ying

Tow new aryltetralin-type lignan glycosides: methyl epipodophyllate 7'-O-beta -D-glucopyranoyl-(1 -->6)-beta -D-glucopyranoside (1), 4-demethylepipodophyllotoxin 7'-O-beta -D-glucopyranoside (2), and a new phenyl ethanol glycoside: phenyl ethanol 4-O-beta -D-glucopyranosyl-(1 -->6)-beta -D-glucopyranoside (3), along with three known compounds: junipetriolosides (4), 3,4-dihydroxy-phenyl ethanol (5), and 4-hydroxy-phenyl ethanol (6) were isolated and identified from the n-butanol extract of the roots and rhizomes of Sinopodophyllum emodi (WALL.) YING. The structures of the above were established by means of spectral data and chemical methods.
