Abstract
New prenylated oxanthrones, vismianol A and vismianol B [(1,3,8,10-tetrahyd roxy-6-methyl-4,5-bis(3-methylbut-2-enyl)anthracen-9(10H)-one) (3a and 3c)] were isolated from the roots of Vismia latifolia (Clusiaceae) as a mixture of two enantiomers, in addition to two other known anthraquinones (chrisop hanol and physcion). The structures were established by 2D NMR spectroscopi c techniques (HMQC, HMBC and NOESY). Copyright (C) 2000 John Wiley & Sons, Ltd.
