Folin-Denis(FD)and Prussian Blue(PB)methods were used to determine the contents of polyphenolics in the ethyl acetate,chloroform and n-butanol fractions of Dioscorea opposita Thunb and D.

Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) and reversed-phase high performance liquid chromatography (HPLC) are applied to establish the methods for characterization of plant polyphenolics and to separate phenolic compounds with excellent physiological and pharmacological activities in Citrus grandis,Myrica rubra and Camellia sinensis.
