Abstract: objective: to sampled from -indeed jiuzhaigou county village and township armour don't YongFengXiang in village village codonopsis pilosula different temperature drying processing, inside the codonopsis were determined, the content of total saponins of codonopsis find the optimal drying temperature range. Methods: using uv spectrophotometry.the every treatment sample codonopsis pilosula, total ginsenosides by 5% vanillin, 70% sulfuric acid as colour-display reagent, detected wavelength for 538nm. Results: two sample pretreatment, low temperature after 60 ℃ drying measured dangshen total ginsenosides is highest, armour for 1.069 & not village micro; G, in the village village for 1.019 & micro; G. Secondly is low temperature pretreatment after airing, armour for 1.065 & not village micro; G, in the village village for micro 1.013 &; G. After comparison, by low temperature pretreatment of samples after measured dangshen total ginsenosides significantly higher than that without low temperature pretreatment samples. Conclusion: the best way to dry codonopsis pretreatment is low temperature after 60 ℃ drying. Keywords: dangshen drying temperature dangshen total saponins ultrasonic extraction
