不同产地南五味子中木脂素分析研究

Determination of lignans in Schisandrae Sphenantherae Fructus from different regions

采用UPLC-TQ-MS技术对不同产地南五味子药材中的7种木脂素类成分进行分析评价,为南五味子的科学药用提供实验依据。结果显示秦岭以南,东侧的商洛市柞水县、山阳县所产南五味子中主要含五味子酯甲、五味子甲素;宝鸡市眉县,安康市石泉县、宁陕县,汉中市略阳县所产的南五味子主要含有安五酯素,其中宁陕县样品中五味子甲素含量也较高;而位于秦巴山区腹地的汉中市南郑县所产的南五味子主要含五味子酚、五味子甲素。总之不同产地的南五味子所含木脂素种类和含量差别很大,在实际应用中应结合现代药理实验和临床研究,根据所治疗疾病相关的主要功效成分对不同产地南五味子药材加以区别入药,以达到药物的最佳疗效。

With an objective to provide an experimental basis for scientific officinal of Schisandrae Sphenantherae Fructus, this research uses UPLC-TQ/MS method to analyze 7 different kinds of lignan in 70 batches of Schisandra sphenantherae Fructus samples from 9 regions. The results showed that in the area south of Qinling mountains, Schisandrae sphenantherae Fructus from Zhashui county and Shanyang county of Shangluo mainly contained schisantherin A and deoxyschizandrin. However, Schisandrae sphenantherae Fructus from Mei county of Baoji, Shiquan county and Ningshan county of Ankang, and Lueyang county of Hanzhong, mainly contained anwuli- gan. Samples from Ningshan county also consists relatively high level of deoxyschizandrin. In the central area of Qinling mountains and the Daba mountains, Schisandrae Sphenantherae Fructus from Nanzheng county of Hanzhong mainly contained schisanhenol and deoxy- schizandrin. In conclusion, the kinds and level of lignan differ significantly in Schisandrae sphenantherae Fructus produced in different regions. In practical application, Schisandrae Sphenantherae Fructus produced in different regions should be distinguished and differently applied based on their main effective components corresponding to different diseases, which can lead to the best clinical use.
