Method for simultaneously testing contents of seven lignans in schisandra chinensis

Abstract

The invention provides a method for simultaneously testing contents of seven lignans in schisandra chinensis. According to the method, a chromatographic column ZORBAX Eclipse Plus C18 column (1.8 [mu]m, 100 mm*2.1 mm) is used; a mobile phase, namely acetonitrile-water, is adopted for gradient elution; the flowing speed is 0.3 mL*minute-1; the column temperature is 40 DEG C; the detection wavelength is 220 nm; and the sample feeding volumn is 1 [mu]L. Results show that components, namely schisandrol A, schisandrol B, schisantherin A, schisantherin B, schizandrin A, schisandrin B and schisandrinC, generally meet linear separation and are in good linear relationship, the average sampling recycling rate is within 98.29-102.5%, and the RSD (Relative Standard Deviation) is within 1.4-1.9%. Testresults show that the method is rapid, stable and reliable and applicable to testing on contents of lignans in southern and northern schisandra chinensis in different production areas, and identification on southern and northern schisandra chinensis.

Description

technical field [0001] The invention belongs to the field of medicine, and relates to a detection technology for active components of traditional Chinese medicinal materials, in particular to a method for measuring the content of seven kinds of lignans in Schisandra chinensis and an application thereof. Background technique [0002] The 2015 edition of the "Chinese Pharmacopoeia" stipulates that Schisandra chinensis (Turcz.) Baill. is the dried and mature fruit of the plant Schisandra chinensis (Turcz.) Baill. The main distribution area extends from Northeast Asia (Russian Far East, North Korea, Korea, Japan) to Northeast my country, North China, and the northern slope of the Qinling Mountains. .2003]. Schisandra sphenanthera is the dry mature fruit of Schisandra sphenanthera Rehd.et Wils. [1] , mainly distributed in Shaanxi, Shanxi, Gansu, Jiangxi, Hunan, Sichuan, Yunnan and other places [See: Chinese Academy of Sciences Editorial Committee of Flora of China. Flora of China...

Problems solved by technology

At present, the liquid phase method for the determination of lignans in Schisandra chinensis generally adopts the HPLC method [see: 1. Wei H, Sun L, Tai Z, et al. A simple and sensitive HPLC method for the simultaneous determination of eight bioactive components and fingerprint analysis of Schisandra sphenanthera[J].Analytica Chimica Acta,2010,662(1):97-104; 2.
