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,5 μm)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...

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 of Eucommiae Folium with the various processing techniques by HPLC fingerprint. The analysis was performed on the Promosil C18(250 mm × 4.6 mm, 5 μm) column. Acetonitrile-0.1% H3PO4 was used as the mobile phase with gradient elution. The scanned wavele...
