The Primary Study On Chemical Componets And Fingerprint Chromatography Of Radix Astragali In Xinjikang Injection

The injection of TCM is a new way in administration of TCM . Xinjikang injection consists of the effective ingredients of Radix Salvia and Radix Astragali according to the basic theory of traditional Chinese medicine. This injection is an effective recipe to cure viral myocarditis ( VMC) . The article adopted modern scientific means such as ultrafitration and macropore adsorbed resin method combined with chemical extracted theory, separated effective compounds. A new kind of modern injection was made. We have made out three batches of injections Astragali.TCM is a complex compound, which contains various ingredients, single or a few ingredients can not reflect the quality of TCM properly. The study on the chemical constituents of Radix was carried out .The study has separated two chemical components, and found up a preliminarily Fingerprint chromatography of Radix Astragali.With the content of onoin and 9,10-dimethoxy-pterocarpan-3-O- ?-D-glucoside as index, this experiment has set up a preliminarily Fingerprint chromatography of intermediate and finished product in Radix Astragali by HPLC. With this condition, the experiment has determined onoin and 9,10-dimethoxy-pterocarpan-3-O- ?-D-glucoside in the three batches of injections.Standard substance of onoin and 9,10-dimethoxy-pterocarpan-3-O- 0 -D-glucoside has also been made. The purity of control substance accords with the demands of the standard. The structure is identified by !H-NMR> 13C-NMR.
