- Abstract
Objective: To study the chemical constituents from n-butanol extracts of Periploca calophylla., Method: The constituents were isolated and purified by chromatographic technology and their structures were elucidated on the basis of physicochemical property and spectroscopic methods., Result: Eight glycosides were isolated and identified as periplocin (I), kaempferol 3-alpha-D-arabinoside (II), kaempferol 3-O-beta-D-glucoside (III), 3',4',5,7-tetrahydroxyflavanone-2(S)-3'-O-beta-D-glucopyranoside (IV), (+)-syringaresinol-4'-O-beta-D-monoglucoside (V), 1-sinapoylglucoside (VI), erigeside C (VII), 2,6-dimethoxy-4-hydroxyphenol 1-O-beta-D-glucoside (VIII)., Conclusion: All the compounds were isolated for the first time from this plant.
