title: Quassinoid glucosides from seeds of Brucea amarissima.
abstract: Quassinoid glucosides, javanicosides I, J, K and L, were isolated from the seeds of Brucea amarissima (Lour.) Desv. ex B. A. Gomes (Simaroubaceae), along with two known quassinoids, i.e. bruceins D and E, and seven known quassinoid glucosides, yadanziosides B, C, E, I and K, bruceoside B and yadanzigan. Their structures were elucidated by analysis of the spectral data and chemical evidence.
