【Abstract】 [Objective]The aim was to study the optimum extracting progress of chlorogenic acid from Lonicera macranthoides Hand.-Mazz.[Method] The optimum extracting condition was investigated by L9(34) orthogonal design with the extraction yield and chlorogenic acid as index.Two different ways of UV and HPLC were carried out for the quantitative and qualitative determination of chlorogenic acid.[Result] The total extract yield was taken as index: 15 folds of water,2 times extraction,extraction temperature 85 ℃ and 30 min.The chlorogenic acid was taken as index: 15 folds of water,2 times extraction,extraction temperature 80 ℃ and 30 min.[Conclusion] This technology was simple,rapid and stable,and could be used to control the quality of Lonicera macranthoides Hand.-Mazz.更多还原
