栾树种子中黄酮类化学成分

STUDY ON THE FLAVONOIDS FROM THE SEEDS OF KOELREUTERIA PANICULATA LAXM

摘要: 目的：分离鉴定栾树(Koelreuteria paniculata Laxm)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(paniculatonoid A, I)和栾树酮B(paniculatonoid B, II)，并归属其波谱信号。

Abstract: 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 ¹³CNMR 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.
