Abstract:
Objective To establish the fingerprint detecting standard for Tanreqing NaCl Injection. Methods Using baicalin as reference substance to calibrate the common peaks by HPLC-ELSD. According to the technical requirements on fingerprint of traditional Chinese medicine injection, their relative retention times and peak area ratios were calculated and the similarity of ten batchs of samples was determined. Results On the basis of systematic methodology, ten batches of injection samples were tested and analyzed so as to establish HPLC fingerprint for the injection. Conclusion The relative retention times and peak area ratios of 16 common peaks on HPLC fingerprint all conform to the requirement. So the established fingerprint can be used as the one of important foundations for quality control of Tanreqing NaCl Injection.
