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-xylopyranosyl-(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.

New lignan glycosides from Chinese medicinal plant, Sinopodophillum emodi.

Two new podophillotoxin glucosides, L-picropodophillotpxin 7'-O-(beta-D-glucopyranosyl-(1-->6)-beta-D-glucopyranoside) (2) and L-picropodophillotpxin 7'-O-beta-D-glucopyranoside (3), were isolated from Chinese medicinal plant, Sinopodophillum emodi, together with 4 known compounds, podophillotoxin (1), podorhizol 4'-O-beta-D-glucopyranoside (4), deoxypodophillotoxin (5), and dehydropodophillotoxin (6). The structures of 2 and 3 were finally determined by the extensive decouping and nuclear Overhauser effect (NOE) experiments in NMR spectra and circular dichroism (CD) spectra. Compound 2 is the second example of podophillotoxin diglucoside, and both the first one and 2 were isolated from S. emodi. X-ray crystal structure analysis of 1, 5, and 6 was carried out. Compounds 1 and 5 showed the different conformations from those reported.
