Abstract:
Taking Hovenia dulcis as material，using acid-base foam method，α-naphthol-sulfuric acid precipitation method，acetic anhydride and sulfuric acid method for qualitative analysis of total saponin content，weight method and bromine method for quantitative analysis in each part of the Hovenia dulcis (including the leaves，branches,fruit，fruit residue，seed，shell)，according to the total saponin extracting rate,the extracting techniques,including extracting temperature,solid to liquid ratio,extracting time were optimized by orthogonal design.The results showed that the total saponin content in stems was the highest.The sample was extracted by pure water,the extracting temperature was 60℃,the ratio of solid-solution was 1∶15 mg/L,the extracting time was 4.0 h(refluxing extraction for 1 times,2 h for each time),and the total extraction rate of Hovenia dulcis fruit was 16.5 mg/g.
