Further isoflavonoid metabolites from Millettia griffoniana (Bail)
摘要:
Three new isoflavonoids, griffonianone A (1), B (2) and C (4) were isolated from the root bark of Millettia griffoniama, along with the known maximaisoflavone G (5) and 7-hydroxy-6-methoxy-3',4'-methylenedioxyisoflavone (6). Their structures were assigned on the basis of spectroscopic data and chemical transformations. (C) 2001 Elsevier Science Ltd. All rights reserved.
