摘要
目的 :分离鉴定栾树 (KoelreuteriapaniculataLaxm)种子的化学成分。 方法 :分别用石油醚回流提取和95 %EtOH浸提 ,硅胶柱色谱分离 ,IR ,MS ,UV ,1HNMR ,13CNMR等方法确定结构。结果和结论 :分得 2个新化合物 ,分别为栾树酮A( paniculatonoidA ,I)和栾树酮B( paniculatonoidB ,II) 。
AIM: To isolate and determine the structure of compounds isolated from the seeds of Chinese medicinal plant Koelreuteria paniculata Laxm. METHODS: The seeds were extracted with petroleum ether and 95% EtOH using a percolator, the 95% EtOH crude extracts were purified by using silica gel chromatography and Sephadex LH 20. IR, UV, MS, 1H and 13 CNMR spectra were employed for structural identification. RESULTS: Two flavonoid glycosides named paniculatonoid A (I) and B (II) were isolated. CONCLUSION: I and II were new compounds.
