Two new terpene glucosides and antitumor agents from Centipeda minima.

One new monoterpene glucoside minimaoside A (1) and one new sesquiterpene glucoside minimaoside B (2), together with four known terpenoids, were isolated from the whole plants of Centipeda minima (L.) A. Braun et Ashers. Their structures were determined by spectroscopic methods. Compounds 5 and 6 showed weak or moderate cytotoxic activity toward several tumor cell lines.
