目的:研究苗药雪里见的化学成分。方法:雪里见用90%甲醇冷浸提取,经D-101大孔树脂柱用不同比例的乙醇水洗脱,对各洗脱部分采用多种柱层析技术进行分离纯化,通过波谱数据分析进行结构鉴定。结果:从雪里见中分离鉴定了8个化合物,分别为:豆甾醇(1)、雪胆甲素(2)、psiguanin A(3)、木栓酮(4)、胸苷(5)、环阿尔廷醇(6)、β-谷甾醇(7)、胡萝卜苷(8)。结论:其中,化合物2~6为首次从该属植物中分离得到,化合物2~6为首次从该植物中分离得到。
Objective: To study the chemical composition of Miao medicine Yoshimi see. Methods: Sekisui ice cold extraction with 90% methanol, the D-101 macroporous resin column with different proportions of ethanol elution, the eluted part of the column chromatography using a variety of techniques for separation and purification by spectral data analysis Structural identification. Results: Eight compounds were isolated and identified from sesame seed: stigmasterol (1), snow hymellose (2), psiguanin A (3) Cycloaltin (6), β-sitosterol (7), daucosterol (8). Conclusion: Among them, compounds 2 ~ 6 were isolated from this genus for the first time, and compounds 2 ~ 6 were isolated from this plant for the first time.
