摘要：

The structure of the major pigment in the purple flowers of Tibouchina urvilleana (Melastomataceae) has been identified as malvidin 3-(p-coumarylglucoside)-5-acetylxyloside [1], a new anthocyanin, by using chromatographic and various nmr techniques involving nOe, HOHAHA, DQF-COSY, DEPT, HMQC, and HMBC. The pigment was found co exist as an equilibrium mixture of the flavylium and the pseudobase forms in the nmr solvent.
