The Effect of Different Processing Methods on Glycosides Content in Forsythia

Objective:To compare the different processing methods on forsythia glycosides content.Method:The column was from the United States waters symmetry columns(250 mm×4.6 mm,5 μm);mobile phase was methanol-water,gradient elution program;flow rate of 1.0 mL/min;detection wavelength was 280 nm;injection volume 20 μL;column temperature:25℃,which were the conditions of high performance liquid chromatography forsythia steam drying products,raw materials in the drying phillyrin content and peak area,and compared with the reference substance phillyrin.result:Forsythia steamed fruit,Sun-dried product contains almost no change in composion,but significantly higher than in the content of the latter on the former.Conclusion:Forsythia in the process of steam drying processing,Sun-dried little effect of its active ingredients,but the steam drying products Forsythin content was better,that showed it better than the raw materials forsythia steam products.
