注射用丹参分子排阻色谱及指纹图谱差减分析

目的 探讨注射用丹参质量差异的分析方法.方法 取临床不良反应有差异的不同批号的样品进行平行比对试验,分别应用凝胶分子排阻色谱、碳十八反相液相色谱进行指纹图谱分析,通过综合差减分析揭示非小分子酚酸类成分信息.结果 注射用丹参的凝胶分子排阻色谱有显著的批间差异,非小分子酚酸类成分批间差异显著,与豚鼠急性毒性反应程度相对应.结论 非小分子酚酸类成分应作为丹参系列注射剂质量控制的重点.提出谱毒学研究是中药注射剂安全性研究的重要方向之一.

Subtractive Analysis of Size Exclusion Chromatography and Fingerprint for Radix Salviae Miltiorrhizae Injection

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.
