Fractionation of Simaba multiflora A. Juss. guided by bioassay has resulted in the isolation of a new antileukemic quassinoid 6alpha-senecioyloxychaparrinone (2) and the previously reported quassinoid chaparrinone (3). The structure of the former has been established by spectral and chemical
A new antimalarial quassinoid, namely, orinocinolide (1), was isolated from the root bark of Simaba orinocensis, together with the previously reported simalikalactone D (2). The structure of 1 was determined primarily from 1D and 2D NMR analysis, as well as by chemical derivatization. Compound 1 was
