ISOFLAVENES FROM THE ROOTS OF CICER JUDAICUM

Three new isoflav-3-enes, droxy-2'-methoxy-4',5'-methylenedioxyisoflav -3-ene (judaicin), judaicin 7-O-glucoside and judaicin 7-O-(6 ''-O-mal onylglucoside), have been isolated from the roots of Cicer judaicum to gether with the known pterocarpans, maackiain 3-O-glucoside and maacki ain 3-O-(6'-O-malonylglucoside). Their structures were determined usin g 1D and 2D NMR techniques in conjunction with other physical methods of analysis. The malonylglucoside derivatives were found to decarboxyl ate in solution to give the corresponding acetylglucosides. Copyright (C) 1996 Published by Elsevier Science Ltd
