Chemical Constituents from Flower of Lonicera fragrantissima

目的：研究郁香忍冬花蕾的化学成分。方法：采用多种层析分离技术进行分离纯化,根据理化性质和波谱数据进行结构鉴定。结果：从郁香忍冬花蕾95%乙醇提取物的乙酸乙酯部分分离得到9个化合物,分别鉴定为：绿原酸（1）、咖啡酸（2）、secologanoside（3）、secoxyloganin（4）、马钱子苷（5）、蔗糖（6）、肌醇（7）、芦丁（8）、金圣草素-7-O-β-D-葡萄糖苷（9）。结论：其中,化合物2~9为首次从该植物中分离得到。

Objective：To study the chemical constituents from the flower of Lonicera fragrantissima. Methods：The chemical constituents were isolated and purified by means of several chromatographic techniques,and their structures were elucidated by spectroscopic methods. Results：Nine compounds were isolated and identified as chlorogenic acid（1）,caffeic acid（2）,secologanoside（3）,secoxyloganin（4）,loganin（5）,sucrose（6）,myo-inositol（7）,rutin（8）,and chrysoeriol-7-O-β-D-glucoside（9）. Conclusion：Compounds 2 ~ 9 are obtained from this plant for the first time.
