摘要
目的对不同产地初加工方式处理杜仲叶进行HPLC指纹图谱的比较研究,阐明不同初加工方式对杜仲叶化学成分的影响,以期筛选出适合杜仲叶的产地初加工方式。方法对所采集的杜仲鲜叶以不同的产地初加工方式进行加工处理,并采用HPLC法,建立用以评价初加工方式优劣的指纹图谱体系。色谱条件:以Promosil C18(250 mm×4.6 mm,5μm)为色谱柱,乙腈-0.1%磷酸水溶液为流动相进行梯度洗脱,扫描波长200～400 nm,检测波长208 nm,柱温25℃,体积流量0.8 mL/min。结果系统研究了杜仲叶的不同产地初加工方式,并建立了评价其优劣的杜仲叶HPLC指纹图谱,确定了22个主要共有峰,但是各共有峰峰面积相差较大,绿原酸、京尼平苷酸等主要有效成分的量有明显差异。结论建立的HPLC指纹图谱分析法可同时用于有效成分的定量测定,该方法重复性好、可操作性强,可较全面地反映不同产地初加工方式处理的杜仲叶间的差异。
Objective To illustrate the influences of various original processing techniques on chemical composition of Eucommiae Folium from different habitats by comparing HPLC fingerprint profiles, so as to select the suitable techniques for processing Eucommiae Folium. Methods To evaluate the quality ofEucommiae Folium with the various processing techniques by HPLC fingerprint. The analysis was performed on the Promosil C ts （250 mm ~ 4.6 mm, 5 ~tm） column. Acetonitrile-0.1% H3PO4 was used as the mobile phase with gradient elution. The scanned wavelength was from 200 to 400 nm, and the detection wavelength was at 208 nm. The flow rate was set at 0.8 mL/min. The column temperature was set at 25 ℃. Results The HPLC fingerprint profiles of Eucommiae Folium by the various processing techniques which were systematically researched were investigated. A total of main 22 common peaks were found, but the areas of the peaks were significantly different. The contents of chlorogenic acid and geniposidic acid obtained by the various processing techniques had the evident differences. Conclusion HPLC fingerprint technique with the application to the content determination of the active ingredients has the good reproducibility and maneuverability. It is one of the potential process analytical techniques to explore the ingredient differences in the processed Eucommiae Folium from different habitats.
