摘要：

From the bulbs of Crinum bulbispermum Milne, four new minor compounds were isolated viz. 4-hydroxy-2',4'-dimethoxydihydrochalcone (1), 4,5-methylenedioxy-4'-hydroxy-2-aldelyde[1,1'-biphenyl] (4), hippacine (6), and 4'-hydroxy-7-methoxyflavan-3-ol (7). In addition, four known compounds were isolated and identified as 2(S),3',4'-dihydroxy-7-methoxy flavan (2), isolarrien (3), isoliquiritigenin (5) and liquiritigenin (8). The structures of the isolated compounds were established by spectral evidence. (C) 2000 Elsevier Science Ltd. All rights reserved.
