Abstract

The invention discloses a method for optimizing a recipe for extracting compound Xuezhining from beta-cyclodextrin based on a fingerprint spectrum technique. The method comprises the following steps: (1) selecting multiple recipe amounts of compound Xuezhining, and respectively preparing a Xuezhining water extract and a Xuezhining beta-cyclodextrin extract; (2) respectively establishing fingerprint spectrums of the uezhining water extract and the Xuezhining beta-cyclodextrin extract, and selecting multiple common fingerprint peaks; (3) carrying out medical material affiliation on the common fingerprint peaks, and calculating a corresponding chromatographic peak area content formula (shown in the description) according to chromatographic peak areas in the common fingerprint peaks; and (4) respectively calculating the minimum values of the chromatographic peak similarities formula (shown in the description) in different medical materials after the optimization according to the chromatographic peak areas of the common fingerprint peaks in the Xuezhining water extract and the peak area content of the common fingerprint peak in the Xuezhining beta-cyclodextrin extract, so as to determine the dosage of each medical material in a final optimized compound Xuezhining recipe.

Description

technical field [0001] The invention relates to a traditional Chinese medicine extraction process, in particular to a method for optimizing the prescription of compound Xuezhining extracted from β-cyclodextrin based on fingerprint technology. Background technique [0002] The traditional Chinese medicine compound Xuezhining is recorded in the 2010 edition of "The Pharmacopoeia of the People's Republic of China". It is composed of four traditional Chinese medicines: cassia seed, shouwu, lotus leaf, and hawthorn. Hyperlipidemia due to stasis. Cyclodextrin (CD for short) and its derivatives are new types of medicinal materials that have developed rapidly in recent years, and have the characteristics of low biological toxicity and good water solubility. β-cyclodextrin (β-CD) is a cyclic oligomer linked by α-1,4-glucosidic bonds obtained from starch fermented by glucosyltransferase, which contains 7 glucopyranose units. With a special molecular structure of internal hydrophobic...
