Effect of habitat processing method on phillyrin and forsythiaside A of Forsythiae Fructus

Objective: To investigate the habitat processing method of Forsythiae Fructus based on the different indexes, and to choose the best habitat producing process.

Methods: The habitat producing process was researched by the L9(3(4)) orthogonal and the single factor test. The contents of phillyrin and forsythiaside A were determined by HPLC.

Results: The contents of phillyrin and forsythiaside A from Forsythiae Fructus processed by evaporating were 1.33-3.05, and 9.71-44.82 mg x g(-1), respectively. The contents of phillyrin and forsythiaside A from Forsythiae Fructus processed by cooking were 4.63-5.46 mg x g(-1), and 40.20-64.84 mg x g(-1), respectively.

Conclusions: With phillyrin and forsythiaside A as evaluation indexes, cooking method is superior to evaporate method while it is superior to dry method. It is conductive to the preservation and stability of phillyrin and forsythiaside A that add 4 times water of material volum and boil 10 min.
