Forming Technology And Quality Standard Of Guang Yanling Power For Injection

Guang Yanling Powder for Injection is a broad-spectrum antiseptic one which is purified from the leaves of Oleacea Syringa plants syringa oblata Lindl.In this article, freezing-dry processing techniques have been systematically studied. So have the influence of different concentration of drug solution and additives, as well as different volumn of solution on freezing-dry processing techniques.In addition, in the progress of preparing drug solution ,the influence of some factors such as pH ,activated charcoal ,SF and running vapour sterilization on active principle have been studied .Meanwhile, the curve of lyophilization or freeze drying was formulated,this experiment made a foundation for the further large-scale production of Guang Yanling Powder for Injection.In order to control the quality and insure the security and efficiency of the Injection, we studied the quality standard, which will improve the quality control Guang Yanling Injection.
