Problems solved by technology

The present invention adopts carbon dioxide supercritical fluid extraction technology to extract the active ingredients of tanshinones in Salvia miltiorrhiza, and uses hydroxypropyl β-cyclodextrin (HP-β-CD) to clathrate them, thereby increasing the tanshinones in the injection. Excellent solubility, which solves the problem of difficult dissolution of fat-soluble components in injections, and improves the quality and clinical efficacy of preparations

Embodiment 1

[0036] 1. Prescription Danshen 1500g

[0037] 2. Extraction: Take the above-mentioned prescription medicinal materials, select them, wash them with deionized water, dry them, and crush them into coarse powder. Take the coarse powder of Danshen, put it in a supercritical fluid extractor, and extract it for 2 hours at an extraction pressure of 22 MPa and an extraction temperature of 45° C. to obtain a supercritical extract of Danshen. Take the supercritical extract of Salvia miltiorrhiza, dissolve it with an appropriate amount of ethanol, add it to the saturated HP-β-CD solution, stir at a constant temperature of 50°C until it becomes cloudy, continue stirring for 1.5h, put it in the refrigerator overnight, filter it with suction, and dry it at low temperature to obtain HP-β-CD inclusion compound powder; take the Danshen medicinal powder after supercritical extraction, decoct and extract three times with deionized water, combine the extracts, concentrate under reduced pressure t...

Abstract

The invention discloses a radix salvia miltiorrhiza injection preparation in the forms of injection, powder injection and freeze dried powder injection and the process for preparation, wherein the preparation mainly comprises tanshinone hydroxypropyl beta-cyclodextrins inclusion compound and radix salvia miltiorrhiza water extract, the tanshinone liposoluble ingredient in the radix salvia miltiorrhiza is extracted through the hypercritical liquid abstraction technique, thus substantially increasing the dissolvability and content of the tanshinone ingredient in the injection.

Description

Technical field [0001] The invention belongs to the field of traditional Chinese medicine pharmacy, and in particular relates to a main component of Danshen injection preparation and a preparation method of the injection preparation. Background technique [0002] Coronary heart disease and angina pectoris are clinically common and frequently-occurring diseases. In recent years, with the improvement of people's living standards, the incidence rate has been increasing year by year. Salvia miltiorrhiza is a traditional traditional Chinese medicine for promoting blood circulation and removing blood stasis. It is clinically used to treat cardiovascular system diseases such as angina pectoris and myocardial infarction. Modern pharmacological studies have shown that the pharmacological effects of Danshen are mainly on the cardiovascular system, which can dilate blood vessels, accelerate blood flow, improve microcirculation, change blood viscosity, increase myocardial blood supply, ...
