摘要：

Two new diterpenes and four known flavones were isolated From the aerial parts of Ophryosporus charrua (Griseb.) Hieron. The diterpenes were characterized as 2-oxo-3 alpha-hydroxy-ent-labd-7-en-15-oic acid and 2-oxo-ent-haliman-1(10), 7-dien-15-oic acid. The structures were established by analyses of their H-1 and C-13 NMR spectra with the aid of 2D experiments and chemical transformations. The flavones were identified as apigenin-7,4'-dimethyl ether, circimaritine, salvigenin, and 7-O-methyleriodictyol. (C) 1997 Elsevier Science Ltd. All rights reserved.
