| Abstract: | In this experiment, Folin reagent absorption spectrometry was used to determine the content of polyphenols compound in Vaccinium uliginosum L. The standard curve of polyphenols compound with good linear relationship was calculated: y=0.0228x-0.0021, R2=0.9994. And the optimal survey condition and the accurate content of polyphenols compound in Vaccinium uliginosum L. was optimazed based on contrast analysis and orthogonal design. The optimal parameters of extracting polyphenols compound were as follow: time 60min, alcohol concentration 60%, ratio of solid to liquid 1:100. |
