Abstract

A freeze dried powder injection is prepared from red sage root and safflower through pulverizing red sage root, proportionally mixing it with safflower, immersing in warm water, filtering, concentrating, depositing in alcohol, regulating pH value, cold storage, filtering, adding water for injection, regulating pH value, adding sodium chloride, and freeze drying.

Description

Technical field: [0001] The invention relates to the technical field of preparation technology of traditional Chinese medicine, in particular to a preparation technology of Danhong freeze-dried powder for injection. Background technique: [0002] Danhong injection is a traditional Chinese patent medicine that has been used for 20 years. Its medicinal ingredients are Danshen and safflower. In the "National Drug Standards (Trial) Promulgation", the published prescription is Danshen 750g , 250g of safflower, 7g of sodium chloride for injection, and made into a 1000ml finished product; in the promulgation, the preparation process of Danhong injection was also announced. Soak twice, 1 hour each time, filter, and use the filtrate for later use; mix the dregs with safflower, add warm water to soak twice, 1 hour each time, filter, combine the filtrates, and concentrate to a relative density of 1.10-1.20 (65°C ) clear ointment, add sodium chloride for injection to isotonicity, adjus...
