Problems solved by technology

The current ministerial standard adopts the method of extracting salvia miltiorrhiza with dilute alcohol, and extracting the dregs after alcohol extraction with safflower. The purification effect is not good, the content of active ingredients is not high, and the injection liquid injection made is unstable. It is also not easy to transport, therefore, its ideal dosage form is freeze-dried powder injection

Embodiment 1

[0057] Example 1: Specification of 10,000 bottles

[0058] (1) Take 15000g of Salvia miltiorrhiza medicinal material, crush it into coarse powder, heat and decoct it with 0.1% sodium bisulfite aqueous solution for 3 times, 60min each time, combine the extracts, centrifuge at 20000r / min, and adjust the pH of the centrifuged liquid with hydrochloric acid Value to 2, refrigerate, filter, add the filtrate to the processed D 101 On the macroporous resin column, first wash away impurities with 2 times the volume of the resin column, and then eluted with 3 times the volume of 30% ethanol, collect the 30% ethanol eluate, and recover the ethanol under reduced pressure to the liquid and crude drugs The ratio of the amount is 1:2, the extracts are extracted 4 times with ethyl acetate, the extracts are combined and the solvent is recovered under reduced pressure to dryness to obtain the total phenolic acid components of Salvia miltiorrhiza.

Abstract

A freeze-dried powder injection is prepared from red sage root and safflower. Its preparing process features that the water-soluble antioxidant is used in hydrothermal extraction, high-speed centrifuge, macroreticular adsorption and ultrafilter by hollow fibre column are used. Its advantages are high curative effect and high quality.

Description

Technical field [0001] The invention belongs to the technical field of traditional Chinese medicine pharmacy, and specifically relates to a traditional Chinese medicine Danhong injection composed of Danshen and safflower and a freeze-dried powder injection for injection and a preparation process thereof. Background technique [0002] Salvia miltiorrhiza is a traditional Chinese medicine. It is widely used clinically in the treatment of cardiovascular and cerebrovascular diseases. Its main active ingredients are water-soluble salvianolic acids, including salvianolic acids A~C, rosmarinic acid and its methyl esters, and salvia miltiorrhiza Chemical components such as protocatechualdehyde, protocatechuic acid, etc., have the effects of anti-platelet aggregation, anti-thrombosis, improvement of microcirculation, anti-oxidation damage, etc., so it can play a role in multiple ways to protect the myocardium and cardiovascular system effect. Domestic researches on water-soluble component...
