摘要：

Two new 6-acylcoumarins, racemosol 1 and mammea A/AC cycle F 2 were isolated by fractionation of a leave extract of Mesua racemosa (Planch. ex Triana and Planch.) Kostermans. Their structures were solved by extensive spectroscopic analysis as 5,7-dihydroxy-8- (2"'-hydroxy-3"'-methylbut-3"'-ene)-6-(1"-oxobutyl)-4-phenyl-2H-benzo[b]pyran-2-one 1 and 5-hydroxy-8-(1"'-hydroxy-1"'-methylethyl)-6-(1"-oxobutyl)-4-phenyl [2',3':5,6]benzo[1,2-b]pyran-2-one 2. Five known compounds namely mammea A/AC 3, mammea A/AC cycle D 4, mammea A/AD cycle D 5, mammea A/BB 6 and mammea A/AA 7 were also isolated from the same source. (C) 1999 Elsevier Science Ltd.
