Abstract

The invention discloses a method for detecting the fingerprints of purple bead nudiflora medicinal materials, intermediates and preparations thereof. The method includes: (a) preparation of reference substance solution; (b) preparation of test sample solution; (c) chromatographic conditions; (d) establishment of standard fingerprint with isoverbacoside as the reference peak; (e) fingerprint quality control. The method is simple in the pretreatment method of each test sample, the characteristic components are kept intact, the repeatability and stability are good, the precision is high, and it has certain specificity; the separation effect of each characteristic peak in the obtained fingerprint is good, and the naked flower The fingerprints of Zizhu medicinal materials, intermediates and preparations have a good correlation; it can be used to identify fake and inferior medicinal materials of Zizhu nudiflora, increase the controllability of the production process of Zizhu nudiflora preparations, and help ensure the production of Zizhu nudiflora preparations stable quality and clinical efficacy. The invention also discloses the standard fingerprints of the Auranthus nudiflora medicinal material, intermediates and preparations thereof obtained according to the fingerprint detection method.

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...
