西南山茶果皮化学成分

Research on Chemical Constituents of Peels of Camellia pitardii

目的:研究西南山茶果皮的化学成分。方法:采用硅胶柱色谱法、Sephadex LH-20柱色谱等方法进行分离纯化,根据波谱学数据和理化性质进行结构鉴定。结果:从西南山茶果皮乙酸乙酯萃取物中分离鉴定了7个化合物,分别为山柰酚(1)、没食子酸(2)、原儿茶酸(3)、齐墩果酸(4)、胡萝卜苷(5)、β-谷甾醇(6)、羽扇豆醇(7)。结论:化合物1～7均首次从西南山茶果皮中分离得到。

Objective：To study the chemical constituents of the peels of Camellia pitardii.Method：Chemical constituents were isolated by various chromatographic methods and were identified by physicochemical characters and spectroscopic analysis or comparison with standard compounds.Result：From the ethyl acetate extract of the peels of C.pitardii,seven compounds were isolated and identified as kaempferol（1）,gallic acid（2）,protocatechuicacid（3）,oleanolic acid（4）,daucosterol（5）,β-sitosterol（6）,lupeol（7）.Conclusion：Compounds 1-7 were obtained from the peels of C.pitardii for the first time.
