Ts. Wu et al., CYTOTOXIC PRINCIPLES FROM SAUSSUREA-LAPPA AND CORYDALIS-TURTSHANINOVII F YANHUSUO, Journal of the Chinese Chemical Society, 44(3), 1997, pp. 357-359
Four protoberberine alkaloids, berberine, palmatine, dehydrocorydaline
and coptisine were characterized as cytotoxic principles from the tub
er of Corydalis turtshnninovii f. yanhusuo. On the other hand, dehydro
costus lactone and costunolide demonstrated cytotoxicity from the root
of Saussurea lappa. Their structures were elucidated by spectral anal
yses.
