Abstract

The invention discloses a callicarpa nudiflora medicine, an intermediate and a fingerprint detection method of a preparation. The method comprises the following steps: (a) preparation of a reference solution; (b) preparation of a test solution; (c) chromatographic condition; (d) formulation of a standard fingerprint of isoacteoside as a reference peak; and (e) quality control of the fingerprint. According to the above method, a pretreatment method of each tested object is simple, characteristic constituents are retained completely, stability is good, precision is high, and there is certain specificity. The separation effect of each characteristic peak in the fingerprint is good. The callicarpa nudiflora medicine, the intermediate and the fingerprint of the preparation have good correlation. The method can be used for identifying quality of the callicarpa nudiflora medicine and increasing production process controllability of the callicarpa nudiflora preparation, and is helpful for guaranteeing quality stability and clinical efficacy of the callicarpa nudiflora preparation. The invention also discloses the callicarpa nudiflora medicine obtained according to the above fingerprint detection method, the intermediate and the standard fingerprint of the preparation.

Description

technical field [0001] The invention belongs to the technical field of drug quality control, and in particular relates to a method for detecting fingerprints of Auranthus nudiflora, intermediates and preparations thereof, and obtains standard fingerprints thereof. Background technique [0002] Callicarpa nudiflora Hook.et Arn. is the dry leaf of Verbenaceae plant. Distributed in Guangdong, Guangxi, Hainan and other places, it grows at an altitude of 1200 meters. The main components of Nadihua Zizhu are flavonoid glycosides, condensed tannins, neutral resins, phenols, polysaccharides, hydroxyl compounds, magnesium, calcium, and iron salts. Modern studies have shown that its active ingredients have hemostatic, antibacterial, astringent, detoxifying, analgesic, and healing-promoting effects. Its antibacterial and antiviral effects, especially have different inhibitory effects on Staphylococcus aureus, typhoid bacillus, and pneumococcus, among which the antibacterial effect on...
