Problems solved by technology

At the same time, due to the complex chemical composition of Polygala medicinal materials, it is relatively one-sided to control the quality of medicinal materials with only a few components, and other components in Polygala medicinal materials may also have an impact on the quality of medicinal materials

Abstract

The invention relates to an UPLC determination method for a polygala root. The method comprises the following steps: step 1, preparation of a control solution: weighing sibiricose A5, sibiricose A6, sibiricaxanthone B, glomeratose A, polygalaxanthone III and 3,6'-disinapoyl sucrose, and fixing a volume by using methanol so as to prepare the mixed control solution; step 2, preparation of a test solution: extracting the medicinal material polygala root with water-containing lower alcohol and carrying out filtering so as to obtain the test solution; and step 3, determination: separately injecting the mixed control solution and the test solution into an ultra-high performance liquid chromatograph so as to obtain chromatograms and calculating the contents of active components in a test substance according to the chromatograms.

Description

Technical field: [0001] The invention relates to a detection method of Chinese medicinal materials, in particular to a UPLC detection method of polygala Background technique: [0002] Polygala is the dry root of Polygala.tenuifolia Willd. or Polygala.sibirica L., a plant of the genus Polygala in the family Polygala. It tastes bitter, pungent, and warm. The effect of swelling is used for insomnia, dreaminess, forgetfulness, palpitations, trance, etc. caused by heart-kidney disharmony. The quality of Polygala medicinal materials available in the market is uneven, the contents of polygalaxanthoneⅢ and 3,6'-disinapoyl sucrose are generally low, and the quality of medicinal materials is difficult to control. In recent years, most of the studies on the quality evaluation of polygala are based on the content determination and analysis of individual components as indicators. Jiang Yong and others carried out the research on the fingerprints of Polygala, but the detection time of t...
