[Objectives]To study and compare the processing methods of Ziziphus jujuba Mill.[Methods]*** was processed by seven methods:cleaning,yellowish frying,burnt frying,carbonized frying,moistening by hot sand,steaming,and ***-visible spectrophotometry was used to determine the content of total flavonoids in each processed ***.[Results]The content of total flavonoids measured by various processing methods was *** content of total flavonoids in the processed *** by moistening by hot sand was relatively high and the absorption peak spectrum was almost the same as that of the cleaned processed *** and the rutin reference substance.[Conclusions]The moistening by hot sand is the optimal method for processing of ***.

[Objectives]The research aimed to optimize extraction technology of total flavonoids from traditional Chinese medicine Yipichou,and establish methods of extraction and content determination of its medicinal materials.[Methods]Using reflux extraction method,total flavonoids of Yipichou were *** single-factor test,influence of extraction method,extraction solvent concentration,extraction volume and extraction time on content of total flavonoids from Yipichou was *** orthogonal test,extraction conditions were optimized,and optimal extraction technology of total flavonoids from Yipichou was obtained.[Results]The optimal extraction process of total flavonoids from Yipichou was as below:70%of methanol,1∶40 of solid-liquid ratio,and 1.0 h of reflux extraction time.[Conclusions]In the test,total flavonoids were extracted from Yipichou,with better repeatability,and stable and feasible method,which could provide certain scientific basis for studying quality standard of this medicinal material.
