目的 采用氢核磁共振(¹H-NMR)代谢组学技术对不同生产厂家的阿胶酸水解成分进行差异性比较。方法 对5个不同生产厂家的阿胶进行酸水解,然后进行¹H-NMR分析。对所得的¹H-NMR图谱进行化学成分归属指认,并结合相关软件进行多元统计分析,找出差异性化学成分。结果 从阿胶¹H-NMR谱中指认出17种化学成分;通过对A、C、D、E厂家生产的阿胶与B厂家生产的阿胶进行比较分析,找出了相应的差异性成分,主要包括异亮氨酸、羟脯氨酸、精氨酸、亮氨酸、苯丙氨酸、缬氨酸、赖氨酸和乙酰丙酸等。结论 ¹H-NMR代谢组学方法可用于不同厂家阿胶化学成分差异性的分析,为阿胶的质量控制提供新方法和新思路。

Objective The variability of the acid hydrolysis ingredients of E'jiao from different manufacturers was analyzed with the ¹H-NMR-based metabolomics approach. Methods E'jiao from five different manufacturers was hydrolyzed using acid and then analyzed using ¹H-NMR. The component belongings were recognized and analyzed combined with relevant software for the multivariate statistical analysis, and then difference components were figured out. Results Seventeen substances were recognized in the ¹H-NMR profiling. After comparing E'jiao from manufacturers A, C, D, and E with that from manufacturer B respectively, the difference components including isoleucine, hydroxyproline, arginine acid, leucine, phenylalanine, valine, lysine, and levulinate were confirmed. Conclusion ¹H-NMR-based metabolomic study on E'jiao from different manufacturers could be used to analyze the difference components, and provide the new way and reasonable idea for quality control study of E'jiao.
