摘要
研究女贞子所含主要化学成分的类型及结构。用φ=95%乙醇回流提取2次,每次1 h,减压回收乙醇后以水洗涤得沉降物。用"YCXY-2号"除杂剂处理后,加活性炭脱色30 min,经凝析分离、纯化精制得产品。采用理化常数测定和薄层色谱、红外光谱、质谱及核磁共振光谱鉴定其化学结构。实验所得产品确证为齐墩果酸,其纯度达99.63%。齐墩果酸为女贞子的主要化学成分。本实验方法简单易行,合理实用,产品纯度高,安全性好,为工业生产提供了技术参考。
To study the types and structure of main chemical components in Ligustrum lucidum. Oleanolic acid was extracted with 95 % ethanol two times, each time 1 h, deposit was obtained after vacuum recovery of ethanol and water rinse Treated with impurity-removing agent ＂YCXY -2＂ , decoloured with active carbon for 30 min, the product was obtained after condensate separation and purification. The chemical sturcture of the product was determined with physical and chemical constants, thin-layer chromatography, infrared spectrosco- py, mass spectrometry and nuclear magnetic resonance spectroscopy. The product was confirmed to be oleanol- ic acid, its purity was 99.63 %. Oleanolic acid is the main chemical component of Ligustrum lucidum. This technology is advanced and rational, practical and feasible. It is applicable to gathering and purification of oleanolic acid. The product safeness is good. It has created the technical conditions for industrial production.
