Abstract

The invention relates to a content determination and identification method of hyperthyroidism resistance powder, which pertains to the technical field of traditional Chinese medicine and particularly relates to measurement and identification method of component content in Chinese medicine preparation. The quality control method comprises the methods of: measuring the content of hesperidin with the chemical formula of C28H34O15 in a medicament by a high performance liquid chromatography (HPLC) method and identifying the following components such as corydalis ambigua, fructus ligustri lucidi, alpha-cyperone and paeoniflorin in the medicament by a thin-layer chromatography (TLC) method. The content determination and identification method for hyperthyroidism resistance powder has the advantages of overcoming the shortage of traditional Chinese medicine, establishing an advanced quality control method for the medicament, utilizing the HPLC method to measure the content of the hesperidin in the medicament and conducting TLC identification on the main components such as the corydalis ambigua, the fructus ligustri lucidi, the alpha-cyperone and the paeoniflorin and the like in the medicament, thus ensuring the accuracy and advancement of the medicament content determination and identification method.

Description

technical field [0001] The invention belongs to the technical field of traditional Chinese medicines, in particular to a method for measuring and identifying components in traditional Chinese medicine preparations. Background technique [0002] Yikang powder is composed of 40.9g of antelope horn, 62g of white peony root, 82g of Tianzhuhuang, 205g of mulberry, 83g of corydalis (vinegar-roasted), 124g of green skin (vinegar-roasted), 41g of Cyperus cyperi, 39g of scrophulariaceae, 43g of Cassia radix, and 59g of Polygonatum. 144g of chrysanthemum, 144g of asparagus, 121g of asparagus, 1083g of ligustrum lucidum, and 16g of rehmannia glutinosa, and the antelope horn file is ground into fine powder; ), Shi Cassia, and Scrophulariaceae are crushed into fine powder; Xanthogonia, Asparagus, Rehmannia, Ligustrum lucidum, and Polygonatum are decocted twice, adding 8 times the amount of water and decocting for 2 hours for the first time, and adding 6 times the amount for the second ti...
