Description

Technical Field

[0001] The invention belongs to the technical field of drug quality detection, and particularly relates to a quality detection method for gynecological Baifeng oral liquid. Background Art

[0002] Gynecological Baifeng Oral Liquid is composed of 20 kinds of medicinal materials, including black chicken, wormwood leaf, Achyranthes bidentata (salt-processed), Bupleurum root, dried ginger, white peony root (fried with wine), peony bark, Cyperus rotundus, Corydalis yanhusuo (vinegar-processed), Anemarrhena asphodeloides, Poria cocos, Coptis chinensis (wine-processed), Gentiana macrophylla, Angelica sinensis, Astragalus membranaceus (roasted), Psoralea corylifolia, Rehmannia root, Rehmannia glutinosa, Fritillaria cirrhosa, and Lycium bark. This prescription has the effect of replenishing qi and nourishing blood, and is mainly used for women with weak body and blood deficiency, irregular menstruation, and abdominal pain during menstruation.

[0003] As a Chinese patent medicine, the efficacy of Fuke Baifeng Oral Liquid is the result of the combined action of multiple active ingredients. In the formula, black chicken nourishes qi and blood, regulates menstruation and relieves pain. When blood is sufficient, qi is harmonious, and when qi and blood are regulated, menstruation is smooth. It is the main medicine; Rehmannia root, Angelica sinensis, White Peony Root, Cyperus rotundus, and Corydalis yanhusuo can greatly nourish the blood, nourish the liver and regulate menstruation, regulate qi and blood, and can treat abdominal pain during menstruation, and achieve the balance of qi and blood. They are all ministerial medicines; Cortex Moutan, Rhizoma Anemarrhenae, Radix Gentianae, Artemisiae Annua, Fritillaria, Coptis chinensis, Cortex Lycii, Dry Ginger, Artemisia argyi, Radix Astragali, and Poria clear and discharge deficiency heat, so that deficiency heat retreats and menstrual blood is calm, and can treat dry throat and dry mouth caused by deficiency heat burning body fluid. They are all adjuvant medicines; Radix Bupleuri and Radix Achyranthis Bidentatae regulate the liver and kidneys, and are all guiding medicines.

[0004] The current quality standard of Fuke Baifeng Oral Liquid included in the surgical gynecology volume of the National Compilation of Standards for Traditional Chinese Medicines has established five qualitative identification methods, including the TLC identification method for the reference medicinal materials of Achyranthes bidentata, dried ginger, Corydalis yanhusuo, paeonol reference substance, berberine hydrochloride reference substance and bamipine hydrochloride reference substance, as well as one component content determination method, paeoniflorin; Xia Jing, Sheng Liling, and Ji Shen studied the quality standard of Fuke Baifeng Oral Liquid and established five qualitative identification methods, including the TLC identification method for the reference medicinal materials of Achyranthes bidentata, dried ginger, Corydalis yanhusuo, paeonol reference substance, berberine hydrochloride reference substance and bamipine hydrochloride reference substance, as well as two component content determination methods, paeoniflorin and gentiopicroside; Song Guiping, Xiao Min, Chen Jun et al. used HPLC to determine the content of one component, paeoniflorin, in Fuke Baifeng Oral Liquid.

[0005] The above methods only monitor one or two quality indicators. Due to the complex ingredients of Chinese patent medicines, the quality control of a single indicator is relatively limited, and it is difficult to fully control the quality of the product. The operation is also relatively complicated.
