Two new aryltetralin-type lignans, isopodophyllotoxin 7 ' -O-beta -D-glucop
yranosyl-(1 -->6)-beta -D-glucopyranoside (1) and 4-demethyl-picropodophyll
otoxin 7 ' -O-beta -D-glucopyranoside (2), along with eight known podophyll
otoxin derivatives: 4-demethyl-podophyllotoxin 7 ' -O-beta -D-glucopyranosi
de (3), podophyllotoxin 7 ' -O-beta -D-glucopyranoside (4), deoxypodophyllo
toxin (5), picropodophyllotoxin (6), podophyllotoxin (7). 4-demethyl-picrop
odophyllotoxin (8), 4-demethyl-podophyllotoxin (9), and 4-demethyl-deoxypod
ophyllotoxin (10), were isolated from the roots and rhizomes of Sinopodophy
llum emodi (WALL.) YING (Berberidaceae). Their structures were identified b
ased on NMR spectral data and chemical evidence.
