Abstract

The invention discloses a method for determining the content of six aristolochic acid components in asarum, and belongs to the technical field of traditional Chinese medicine, a UPLC-MS/MS method is adopted for simultaneously determining the content of aristolochic acid A, aristolochic acid B, aristolochic acid C, aristolochic acid D, aristolochic acid III and aristolochic acid VIIa in asarum, the specificity is higher, more components are controlled, different medicinal parts are comprehensively measured and analyzed, so that the quality of the medicinal material is more comprehensively evaluated, and a basis is provided for reasonable application of the asarum medicinal material.

Description

technical field [0001] The present invention relates to a method for determining the content of six aristolochic acid components in Herba Asarum, specifically, to a method for simultaneously determining Aristolochic Acid A, Aristolochic Acid B, Aristolochic Acid C, Aristolochic Acid C, The invention discloses a method for determining the contents of six components of aristolochic acid D, aristolochic acid III and aristolochic acid VIIa, and belongs to the technical field of traditional Chinese medicines. Background technique [0002] Aristolochic acid (AA) is a nitrophenanthrene compound mainly found in Aristolochia plants. Due to the strong carcinogenicity of aristolochic acid, since 2003, my country's drug regulatory authorities have successively canceled the quality standards for medicinal materials such as Aokita, Guanmutong, Fangji, Tianxianteng, Aristolochia, etc., "Chinese Pharmacopoeia" 2020 edition one Only asarum is included in the book. Asarum is the dried roots ...
