Problems solved by technology

The present inventor obtained quercetin-7-O-glucoside in the separation of the effective components of eucalyptus. According to the comparative analysis of the above-mentioned documents, the plant contains kaempferol-7-O-glucoside and quercetin-glucoside in addition to eucalyptus. Except for the two components of 7-O-glucoside, there have been no reports of other plant species containing the above two components at the same time so far. The inventor believes that if the above two components can be detected simultaneously in the quality control of Zhemu and its preparations, not only can the quality be significantly improved. The specificity of the control items, and the expansion of the number of active ingredients, is conducive to further improving the quality control system of Zhemu and its preparations

Abstract

The invention relates to a new application of quercetin-7-O-β-D-glucoside and discloses the application of quercetin-7-O-β-D-glucoside in quality control of eucalyptus or eucalyptus preparations. At the same time, the invention also discloses a new method for controlling the quality of eucalyptus or eucalyptus preparations, including detecting the content of quercetin-7-O-β-D-glucoside. The disclosure of the present invention provides a brand-new index-quercetin-7-O-glucoside for the quality control of Zhemu or Zhemu preparations, which well makes up for the defect of single quality control index of Zhemu preparations, and improves the quality control of Zhemu preparations. Quality control system.

Description

technical field [0001] The invention relates to a new application of a known compound, in particular to the application of quercetin-7-O-glucoside in the quality control of eucalyptus or its preparations. Background technique [0002] Zhemu is a deciduous shrub or small tree of the genus Cudrania tricuspidata (Carr.) Bun in the Moraceae family. Its function is to clear away heat and cool blood, and it is used for digestive tract tumors in modern folk. The main chemical components are flavonoids, xanthones, lignans, coumarins and polysaccharides. From the 1970s to the 1990s, domestic and foreign scholars (China, Japan and South Korea) conducted research on the anti-cancer effects of Zhemu, and basically confirmed that Flavonoids are anti-cancer and anti-cancer effective components of Zhemu. Polysaccharides participate in immune regulation and have a synergistic effect on anti-cancer. [0003] In China, the development of medicines related to Zhemu began in the 1960s. The suc...
