Abstract
The roots of Dorstenia psilurus yielded three phenolic compounds: 6,8-dipre nyl-3'[O],4'-(2,2-dimethylpyrano)-3,5,7-trihydroxyflavone, 3,6-diprenyl-8-( 2-hydroxy-3-methylbut-3-enyl)-5,7,2',4'-tetrahydroxyflavone and an unusual B/C ring modified flavonoid derivative for which the names dorsilurins C, D and E, respectively, are proposed. Structures were elucidated on the basis of spectral analysis. (C) 1999 Elsevier Science Ltd. All rights reserved.
