胡蔓藤(Gelsemium elegans banth.)属马钱科Loganiaceae胡蔓藤属植物,又名钩吻,断肠草等,药用其根、叶或全草。有大毒,多作外用,祛风止痛,消肿拔毒。 为了探讨胡蔓藤生物碱的药用价值,充分利用资源,进一步了解胡蔓藤全草中各部位生物碱的组成及其毒性,以便控制质量及保证用药安全,我们对胡蔓藤全草进行了有关化学方面的研究。采用薄层光密度法扫描测定胡蔓藤中生物碱甲,碱乙,碱丙,绿碱,碱子及素甲等六种生物碱的方法,并对全草进行了分析。 Gelsemium elegans banth. is a member of the genus Humantan of the Loganiaceae family in Munchow. It is also known as hook-and-kiss, heartbrowed grass, etc., and its roots, leaves, or whole plant are used medicinally. There is a big poison, more for external use, Qufeng pain, swelling and detoxification. In order to explore the medicinal value of Alnus mellifera and make full use of resources to further understand the composition and toxicity of various alkaloids in the whole plant of Humanteng in order to control the quality and ensure the safety of the medication, we conducted chemical research on Alpinia paniculata. . Thin-layer densitometry was used to scan and determine alkaloids A, B, B, C, L, Al, and A, and the whole plant was analyzed.
