目的 研究结香属藏药绿萝花（滇结香Edgeworthia gardneri干燥花蕾）的化学成分。方法 利用硅胶、AB-8大孔树脂、sephadex LH-20、pre-HPLC等色谱方法对绿萝花进行分离纯化，根据理化常数测定及波谱数据分析鉴定化合物结构。结果 从绿萝花70%乙醇提取物中分离得到4个化合物，分别鉴定为绿萝花苷C（1）、西瑞香素-5-O-β-D-吡喃葡萄糖基-（1→2）-β-D-吡喃葡萄糖苷（2）、（3S）-1，2，3，4-四氢-β-咔啉-3-羧酸（3）、二氢山柰酚（4）。结论 化合物1为新化合物，化合物4为首次从该属植物中分离得到。

Objective To study the chemical constituents from the flowers of Edgeworthia gardneri. Methods The chemical constituents were isolated and purified by column chromatography on silica gel, AB-8 macroporous resin, sephadex LH-20, pre-HPLC. Their structures were determined on the basis of physicochemical properties and spectral analysis. Results Four compounds were isolated from the flowers of E. gardneri and elucidated as gardnerol C (1), daphnoretin-5-O-β-D-glucopyranosyl- (1→2)-β-D-glucopyranoside (2), (3S)-1,2,3,4-tetrahydro-β-carboline-3-carboxylic acid (3), and dihydrokaempferol (4). Conclusion Compound 1 is a new coumarin named gardnerol C, and compound 4 is obtained from the genus for the first time.
