New quassinoids, javanicolides C and D and javanicosides B--F, from seeds of Brucea javanica.

摘要: Two new quassinoids, javanicolides C and D, five quassinoid glucosides, javanicosides B-F, were isolated from the seeds of Brucea javanica, along with eight known i.e., yadanziolides A, C, S, bruceins D E, brusatol, aglycone yadanzioside 19 yadanziosides A-G, I, K-P, bruceosides A-C bruceantinoside A. Their structures elucidated by analysis spectroscopic data chemical evidence.
