Abstract

OBJECTIVE To study the chemical constituents of Lonicera syringantha.METHODS The chemical constituents were isolated and purified with column chromatography and the structures were elucidated by spectral analysis. RESULTS Six compounds were isolated and their structures were identified as scopoletin (Ⅰ),aeculetin (Ⅱ),scopolin (Ⅲ),syringin(Ⅳ),kaempferol-3-O-β-D-glucoside(Ⅴ),nonacosane (Ⅵ),glucose(Ⅶ),β-sitosterol (Ⅷ) and stigmasterol(Ⅸ). CONCLUSION Compound Ⅰ,Ⅲ and Ⅳ are isolated from the genus Lonicera Linn for the first time and others are firstly isolated from this plant.
