RESUMO
Syringae Folium (SF) is a traditional Chinese medicine with excellent antibacterial, anti-inflammatory, and antiviral properties. It is widely distributed in northeast China and has three origins. However, the differences between the three origins have never been compared. Here, we used the five-wavelength fusion HPLC fingerprint technique combined with chemometric analysis and the comprehensive quantitative analysis of active constituents to evaluate the quality of SF from different origins, localities, and harvesting times. As a result, SF from different origins and localities showed no differences by similarity analysis, chemometric analysis, and quantitative analysis, whereas the harvesting time was found to be the key factor inducing the variation of the SF composition. In summary, the differences in origins and localities would not cause apparent disparities, while the harvest time should be considered in the SF development and application.
