基于双波长HPLC指纹谱的一级系统指纹定量法鉴定木香顺气丸质量

建立木香顺气丸(Muxiangshunqi pills, MXSQP)双波长HPLC指纹图谱, 用一级系统指纹定量法鉴定其质量. 采用RP-HPLC法, 以橙皮苷(HI)为参照物峰, 在265和326 nm下分别检测获得60和56个共有指纹峰. 以S_m和P_m为指标用系统聚类分析分别确定其中11批和12批样品指纹图谱生成265和326 nm对照指纹图谱(RFP), 并以此二个RFP为标准用一级系统指纹定量法分别评价16批样品. 分别用权重法、均值法和投影参数法整合双波长指纹谱的宏定性和宏定量信息, 用一级系统指纹定量法鉴定MXSQPs质量. 上述五种方法鉴别出12批质量基本合格, 4批含量明显不合格. 基于不同波长及双波长整合谱的一级系统指纹定量法能够对中药系统的化学指纹进行整体定性分析和整体定量分析, 是评价中药质量的便捷有效方法.

Identifying MXSQP Quality by the Firstly Systematically Quantified Fingerprint Method Based on Dual Wavelength HPLC Fingerprints

To develop the dual wavelength HPLC fingerprints of Muxiangshunqi pills (MXSQP) and iden- tify their quality by firstly systematically quantified fingerprint method (FSQFM). The chromatographic fingerprints (CFPs) were determined by reversed-phase HPLC,in which the CFPs containing 60 and 56 co-possessing peaks in the wavelength of 265 and 326 nm respectively when the Hesperidin (HI) peak was marked as the referential peak. Sixteen batches of MXSQPs were identified with the hierarchical clustering analyses b...
