| Abstract: | The extraction technology of caffeotannic acid from leaves of Lonicera confuse DC. was studied with water as solvent,realize its economic value. The effect of chlorogenic acid on the extraction efficiency was studied by single factor experiment,and the process conditions were optimized using the orthogonal experiment. Single factor experiment results showed that the extraction efficiency of chlorogenic acid reached the highest with extraction temperature 100℃,pH 3,extraction time 1.5 h,and material to solvent 1：16. The orthogonal experiment results showed that optimized conditions were obtained as follows：extraction temperature 100℃,pH 4,extraction time 1 h,material to solvent 1：18,and the extraction ratio of caffeotannic acid was 2.83% in the optimized conditions. The orthogonal experiment could make up for the deficiency of single factor experiment,and improve the extraction ratio of caffeotannic acid,the method was simple,feasible,economic,applicative,environmental,fit industrialized production. |
