Abstract

From the EtOH extract of the leaves of Rollinia laurifolia Schl. (Annonaceae), a novel acetogenin, rolifolin (= 3‐(9‐{(2__R__*,5__S__*)‐5‐[(1__S__*,4__S__*)‐1,4‐dihydroxy‐4‐{(2__S__*,5__R__*)‐5‐[(1__S__*)‐1‐hydroxyundecyl]tetrahydrofuran‐2‐yl}butyl]tetrahydrofuran‐2‐yl}‐2,3‐dihydroxynonyl)‐5‐methylfuran‐2(5__H__)‐one; 1) was isolated, together with the known acetogenin annonin‐I (2). Also, from the corresponding hexane extract, a mixture of rolilaurin (3, a novel compound), uvariamicin‐I (4), and uvariamicin‐II (5) was obtained. The structures of compounds 1–5 were elucidated by NMR and MS analysis, and relative configurations were established. Compounds 2 and 5 have never been obtained before from Rollinia.
