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-α-D-arabinoside (Ⅱ), kaempferol 3-O-β-D-glucoside (Ⅲ), 3′,4′,5,7-tetrahydroxyflavanone-2(S)-3′-O-β-D-glucopyranoside (Ⅳ), (+)-syringaresinol-4′-O-β-D-monoglucoside (Ⅴ), 1-sinapoylglucoside (Ⅵ), erigeside C (Ⅶ), 2,6-dimethoxy-4-hydroxyphenol 1-O-β-D-glucoside (Ⅷ). Conclusion: All the compounds were isolated for the first time from this plant.
