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