New phenolic components of Didymocarpus pedicellata.
A chemical investigation of Didymocarpus pedicellata has resulted in the isolation of 8-hydroxy-5, 6, 7-trimethoxy-flavanone, 2'-hydroxy-4', 5', 6'-trimethoxychalcone, 5, 6, 7, 8-tetramethoxy flavanone, pedicellin, methyl pedicin and beta-sitosterol. 8-Hydroxy-5, 6, 7-trimethoxy flavanone and 2'-hydroxy-4', 5', 6'-trimethoxy chalcone are hitherto new natural products while 5, 6, 7, 8-tetramethoxy flavanone has been isolated from D. pedicellata for the first time.
