本文用高速液相层析法检查了不同地区华中五味子中主要有效成份五味子酯甲、乙及丙的含量,结果差异很大。同时从陕西恒口产的华中五味子中分得一新木脂体,经制备衍生物、氧化及光谱分析,其结构为 Ib,命名为 d-epigalbacin。 In this paper, high-speed liquid chromatography was used to examine the contents of the main effective components of schisandrin A, B, and C in different regions of Huazhong Schisandra. The results were quite different. At the same time, a new lignan body was obtained from the Chinese schisandra chinensis produced in Hengkou, Shaanxi Province. After preparation, oxidation and spectral analysis, the structure was Ib, and was named as d-epigalbacin.
