贯叶连翘为金丝桃科金丝桃属植物Hypericum perforatum L.,全草主要含黄酮类化合物、金丝桃素(quercin)及伪金丝桃素(pseudohypericin)等,报道该药材具有抑菌、降压等作用,金丝桃素具有抑制中枢神经和镇定作用,曾作中枢神经抑制药,并有滋补作用,贯叶连翘主要分布在河北、陕西、山东、江苏、四川及贵州等省,我州主要分布在昭觉、盐源及盐边等县,并且资源丰富。由于该药材的多种疗效,国内外都积极进行研究开发。作者采用薄层色谱对其主要化学成分进行对照检识,对主要质量指标金丝桃素采用紫外扫描,测定该化合物的紫外吸收光谱,以拟定含量测定标准。实验结果报道如下。
Hypericum perforatum is Hypericum perforatum L., which contains flavonoids, quercin, and pseudohypericin. It is reported that this herb has antibacterial properties. Hypertensive and other effects, hypericin inhibits the central nervous system and calming effect, once as a central nerve inhibitory drug, and have a nourishing effect, St. John’s wort is mainly distributed in Hebei, Shaanxi, Shandong, Jiangsu, Sichuan and Guizhou provinces, the state It is mainly distributed in counties such as Zhaojue, Yanyuan and Yanbian, and is rich in resources. Due to the various curative effects of this medicinal material, research and development are actively conducted at home and abroad. The author used thin layer chromatogram to carry on the contrast examination to its main chemical composition, to the main quality index hypericin adopts the ultraviolet scan, measured this compound ultraviolet absorption spectrum, proposed the content determination standard. The experimental results are reported below.
