Abstract

Annonin I (1) and anonin VI (9) were isolated from the seeds of Annona squamosa L. (Annonaceae). The constitution of 1 is identical with that of squamocin, isolated by Fujimoto et al. (8). The relative configuration of 1 was elucidated by X-ray diffraction analysis of a derivative. The constitution and relative configuration of 9 was established by 13C- and 1H-NMR spectroscopy using data of derivatives.
