A new cytotoxic stigmastane steroid from Pistia stratiotes.
A new cytotoxic stigmastane, 7beta-hydroxy-4,22-stigmastadien-3-one (3), together with two known cytotoxic stigmastanes (1, 2) and a norisoprenoid (4), have been isolated from the aquatic plant pistia stratiotes. The structure determination was accomplished by spectroscopic methods.
