Only two monoprenylated flavanones have so far been identified from Dorstenia species. As we have mentioned earlier 78 was obtained from the thermal reaction of 4-hydroxylonchocarpin (47). Twigs of D. poinsettifolia yielded dorspoinsettifolin (79). Cyclization of 48 in formic acid and methylation of 78 with diazomethane both readily gave 79. An isomeric compound, 6-methoxyisolonchocarpin, has been reported from Lonchocarpus subglauscescens [61]. [Pg.780]
