Abstract

The invention provides a method for detecting achyranthes root. The method utilizes a UPLC detection method. The method uses 3-O-[alpha-L-rhamnopyranosyl(1-to-3)-beta-D-pyrano-glucuronic acid]-oleanolic acid-28-O-(beta-D-glucopyranose) as an index component for detection of achyranthes root. The UPLC is used for detecting the index component in achyranthes root. The method has good stability and reproducibility, can effectively separate the index component and other components, realizes qualitative research of the index component and satisfies quantitative detection requirements.

Description

technical field [0001] The invention relates to the field of quality detection of traditional Chinese medicinal materials, in particular to a detection method of Achyranthes bidentata. Background technique [0002] Red Achyranthes bidentata is a commonly used clinical medicinal material in Yi medicine in Liangshan Yi Autonomous Prefecture of Sichuan, Chuxiong Yi Autonomous Prefecture of Yunnan, Guizhou and other Yi ethnic areas. It is the root of Cyathula Capitata (Wall.) Moq., a plant of the family Amaranthaceae, and is used to treat bruises, rheumatism, rheumatoid and other diseases. [0003] The domestic and foreign research on Achyranthes bidentata mainly focuses on Achyranthesbidentata Blume and Cyathula officinalis Kuan, which are commonly used in TCM clinical practice; there are few related studies on Achyranthes bidentata. Achyranthes bidentata is a commonly used clinical medicinal material in Yi medicine in Liangshan Yi Autonomous Prefecture of Sichuan, Chuxiong Y...
