Abstract: AIM To assign the ¹HNMR finger print of the root bark of Celastrus angulatus. METHODS Silica gel column chromatography was used to separate the chemical constituents of CGE A of the root bark of C.angulatus. The characteristic signals of the 1HNMR finger print were assigned after determining the structures of the compounds isolated from CGE A. RESULTS ¹HNMR fingerrints of the samples of C.angulatus collected from different regions showed highly characteristic features and reproducibility. Three compounds predominant in CGE A were isolated and their structures were determined by spectral analysis as: angulatin A (1), angulatin B (2) and angulatin C (3). CONCLUSION Compound 3 is a new compound. Compound 2 was isolated from C.angulatus for the first time. The ¹HNMR finger print of CGE A of the root bark of C.angulatus showed mainly the characteristic signals of the above three compounds and might be utilized for the original authentication of this plant.
