Two new quassinoid glycosides, the javanicinosides B and C, and the new quassinoid, javanicin B, were isolated from the bark of the Indonesian Picrasma javanica. In addition, known quassinoid glycosides, the picrasinosides B and F, were also identified. The structures were determined by spectroscopi...
