title: Flavonoids of Dikamali: A phytochemical reinvestigation.
abstract: Eleven known flavonoids (1-11) were isolated from Dikamali, the gum resin of Gardenia lucida. Three of them, desmethylnobiletin, pectolinarigenin and xanthomicrol, are a new report from this source. Nuclear magnetic resonance (NMR) data are being given for all the isolates. For two of them, viz., 3',4'-dimethoxywogonin and 4'-hydroxywogonin, such data have not been reported in literature. Furthermore, correct NMR data are being provided for gardenin C as the data reported in literature were found to be incorrect.
