摘要:
Five new trichilin-type limonoids, named 12-deacetyltrichilin I (1), 1-acetyltrichilin H (2), 3-deacetyltrichilin H (3), 1-acetyl-3-deacetyltrichilin H (4), 1-acetyl-2-deacetyltrichilin H (5), together with four known trichilins, meliatoxin B-1 (6), trichilin H (7), trichilin D (8) and 1,12-diacetyltrichilin B (9) were isolated from the extract of the root bark of Melia azedarach. The structures were elucidated by spectroscopic means and their cytotoxic activities against P388 cells in vitro were tested by means of MTT assay. Copyright (C) 1996 Elsevier Science Ltd
