Abstract

The invention relates to a method of enriching and purifying total flavonoids of all grass of cardamine tangutorum. The method comprises the following steps: (1) preparing extract of the all grass ofcardamine tangutorum; (2) loading the extract of the all grass of cardamine tangutorum on a macroporous resin adsorption column, wherein the loading quantity is 8-48ml of the extract for each gram ofdry macroporous resin, and the flow is 3-4BV/h; after the loading, washing with water and then eluting with ethanol, wherein the volume fraction of ethanol is 10-90%, and the flow is 2-8BV/h; collecting the eluent and detecting the content of total flavonoids. The technology is stable and feasible, provides test data and scientific basis for the enrichment and purification of the total flavonoidsof the all grass of cardamine tangutorum, and lays a foundation for further studying the active chemical ingredients in the all grass of cardamine tangutorum and studying the digestion promoting function of the all grass of cardamine tangutorum.

Description

technical field [0001] The invention relates to a method for enriching and purifying total flavonoids of chrysanthemum. Background technique [0002] Cardamine L. is a cruciferous plant. There are about 160 species in the world. They are mainly distributed in temperate regions, where they grow in plains, mountains, sandy land or fine stone land. in calcareous soils. The resource survey shows that: there are 39 kinds of plants of the genus Orina in our country, accounting for about 30% of the total number of Orina genus, and they are distributed in various places in the north and south of my country. The representative plants of the genus are mainly purple-flowered oryza, white-flowered oryza, big-leaf oryza, Chinese central oryza, spring-cracked oryza, paddy-field broken oryza, pot-pot broken oryza, and Viola leaf Broken rice chestnuts, etc. In the prior art, mainly focus on the separation research of the chemical constituents of the broken rice chestnuts in central China...
