Problems solved by technology

The original form of baicalin in Scutellaria baicalensis is in the form of magnesium salt. This form has good water solubility and can be extracted by dissolving in water, but the acid precipitation destroys its original structure, making the water solubility of baicalin worse and absorption Slow speed, low bioavailability, and reduced efficacy of baicalin

Abstract

The invention relates to a baicalin magnesium compound and further relates to a preparation method and extracting method of the baicalin magnesium compound.The preparation method comprises the steps of baicalin suspension preparation, magnesium ion mixed suspension preparation, reaction, drying and the like.The extracting method comprises macroreticular resin preprocessing, extracting, adsorbing and eluting, concentrating and drying, purifying and the like.The prepared baicalin magnesium restores the existing way of baicalin in scutellaria baicalensis and can replace scutellaria baicalensis to be used as medicine.Compared with the baicalin, the baicalin magnesium compound has the advantages that the solubility is greatly improved, the oral absorption speed is higher, the bioavailability is higher, and the baicalin magnesium compound can very conveniently prepared into water-soluble injection or powder injection.Pharmacological experiments indicate that the pharmacological activity of baicalin magnesium is superior to that of baicalin.

Description

【Technical field】 [0001] The invention belongs to the technical field of medicine. More specifically, the present invention relates to a magnesium baicalin compound, a method for extracting and preparing the magnesium baicalin compound, and an application of the magnesium baicalin compound. 【Background technique】 [0002] Scutellaria baicalensis was first recorded in "Shen Nong's Materia Medica", and it is the dried root of Scutellaria baicalensis Georgi, a plant of the Labiatae family. Baicalin is a flavonoid compound contained in Scutellaria baicalensis with the molecular formula C 21 h 18 o 11 , the content in Scutellaria baicalensis is more than 9% by weight, even as high as 20% by weight, and is one of the main active ingredients of Scutellaria baicalensis. [0003] Modern pharmacological studies have shown that baicalin has the functions of scavenging oxygen free radicals, antiarrhythmia, expanding cardiovascular and cerebrovascular, lowering blood pressure and sed...
