Problems solved by technology

[0007] The existing preparation process of Mailuoning Injection adopts water extraction and alcohol precipitation method to extract four medicinal materials simultaneously, and then extracts the active ingredients with ethyl acetate (see "Technical Method of Mailuoning Injection", Publication No. CN1078148A), However, the prescription contains chlorogenic acid and other components that are unstable to light and air, and the color change of the injection solution and the content of active ingredients are prone to decrease during storage. At the same time, there are organic acids and alkaloids in the prescription. These components are prone to flocculation and precipitation under the state of water injection, which seriously affects the safet

Abstract

The invention discloses a Mailuoning powder injection and method for controlling its quality, wherein the medicament is prepared from Dendrobium nobile, achyranthes and cyathula root, scrophularia root and honeysuckle flower through steps of proportioning, extracting effective constituents, charging medicinal excipient, carrying out hyperfiltration, adjusting pH, degerming and filtering, freeze drying to obtain freeze dried powder injections. The quality control method consists of discriminating four kinds of Chinese herbs and contents of Scoparone, cinnamic acid and chlorogenic acid.

Description

technical field [0001] The present invention relates to a Mailuoning injection preparation, in particular to a Mailuoning injection preparation and a quality control method thereof. Background technique [0002] Mailuoning injection is a traditional Chinese medicine compound injection developed on the basis of the famous medical prescription "Simiao Yong'an Decoction". inflammation, arteriosclerotic obliterans, cerebral thrombosis and sequelae, polyarteritis, acute arterial embolism of extremities, diabetic gangrene, venous thrombosis and thrombophlebitis, etc. Chinese patent CN1557398A discloses that it also has the effect of preventing and treating angina pectoris. The main components and pharmacological effects of the four APIs are: [0003] Honeysuckle is the dried flower buds or flowers with early blooming of Lonicera japonica Thunb., Lonicera hypoglauca Miq., Lonicera confusa DC. or Lonicera dasystyla Rehd. It mainly contains organic acids. The currently identified ...
