摘要：

Seeds of Porcelia macrocarpa afforded two acetogenins: (2S,3R,4R)-3-hydroxy-4-methyl-2-(9-n-eicos-1-enyl) butanolide and the corresponding 9-n-eicosanyl derivative. Their absolute stereochemistries were determined by chemical H-1 and C-13 NMR and mass spectroscopic methods. Copyright (C) 1997 Elsevier Science Ltd
