ABSTRACT
Objective To establish the quality standard for Huamoyan Tablet. Methods Radix Salviae MiltioiThizae and Radix Cyathulaewere were identified by TLC. The content of protocatechuic aldehyde was determined by HPLC. Results The spots on TLC plates were clear without the interference of negative control. Protocatechuic aldehyde showed a good linear relationship in the range of 0. 021～0. 105 μg, r=0. 999 9. The average recovery was 98. 13 % ,and RSD=2. 41%. Conclusion The method is simple, sensitive and accurate, and can be used to control the qual-ity of Huamoyan Tablet.
ABSTRACT
Objective To explore the the analytical method for the quality difference of Radix Salviae Mihiorrhizae (RSM) injection. Methods Parallel intercomparison experiment was carried out in different batches of RSM injection samples which had different degrees of adverse drug reaction. The samples were analyzed by gel size exclusion chromatog-zraphy and C18 HPLC fingerprint. Subtractive analysis was used to reveal the information of the non-low molecular weight phenolic acids. Results There were obvious differences between the results of size exclusion chromatography. The amount of the non-low molecular weight phenolic acids from different batches of the samples was also different, which was correlated with the degrees of acute toxicity in guinea pigs. Conclusion The amount of the non-low molecular weight phenolic acids varies with different batches of Radix Salviae Mihiorrhizae injection. It is suggested that non-low molecular weight phenolic acids can be used for the quality control of Radix Salviae Mihiorrhizae injection. For the first time, the perspective that the corresponding relationship between the fingerprint and their toxicities of Traditional Chinese medicine injection may be one of the most important fields is put forward.
