Problems solved by technology

[0003] At present, there are mainly granules, capsules, tablets, dispersible tablets, mixtures, soft capsules, suppositories, etc. in the market. The quality standards of the above-mentioned preparations are only part of the preparations. The content of total flavonoids has been determined by ultraviolet spectroscopy Photometric method, the quantification is very inaccurate, there is no method for the determination of the content of verbascoside in the nude flower purple pearl preparation

Abstract

The invention discloses a method for measuring the content of verbascoside in a callicarpa nudiflora preparation, relating to a method for measuring the content of effective ingredients in the callicarpa nudiflora preparation. A high performance liquid chromatography (HPLC) is used for measuring the content of verbascoside in the test article solution of the callicarpa nudiflora preparation. Chromatographic conditions and system suitability are as follows: octadecylsilane chemically bonded silica is used as a filler, a flowing phase contains an organic solvent and an acidic solution, the volume percent of the organic solvent in the flowing phase is 10-30%, the volume percent of the acidic solution in the flowing phase is 70-90%, the concentration of the acidic solution is 0-0.3%, and the detection wavelength is 322-345nm. The method disclosed by the invention can be used for accurately and effectively measuring the content of verbascoside in the callicarpa nudiflora preparation, has a small error, can further improve the quality standard of the callicarpa nudiflora preparation, and can ensure the quality and clinical effect of the callicarpa nudiflora preparation.

Description

technical field [0001] The invention relates to a method for determining the content of active ingredients in the nudibranch preparation, in particular to a method for determining the content of verbascoside in the nude flower preparation. Background technique [0002] Callicarpanudiflorae is a small shrub plant of Verbenaceae, which has the functions of hemostasis, antibacterial, astringent, detoxification, analgesia, and promotion of healing. Its antibacterial and antiviral effects, especially have different inhibitory effects on Staphylococcus aureus, typhoid bacillus, and pneumococcus, among which the antibacterial effect on Staphylococcus aureus and typhoid bacillus is the strongest. Nadihuazizhu can also inhibit the permeability of capillaries, and has obvious anti-inflammatory effect on early inflammation exudation and swelling. The main components of Nadiflower are flavonoid glycosides, condensed tannins, neutral resins, phenols, polysaccharides, hydroxyl compounds,...
