Title: Acetogenins from the Leaves ofRollinia laurifolia
Abstract: Abstract From the EtOH extract of the leaves of Rollinia laurifolia S chl . (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.
