The extraction technology for anthocyanins from Lablab purpureus was explored. The anthocya?nins were quantitatively analyzed through the pH differential method.The optimal extraction technological con?ditions were obtained by single factor and orthogonal experiments.The results showed that the maximum extrac?tion of anthocyanin content was 0.733 1 mg/g under the optimal extracting conditions,which were as follows:pH=3,ethanol concentration 60%,temperature 70 ℃,solid-liquid ratio 1 ∶ 12,extraction time 60 min. At the same time,the purification process with resin for anthocyanins from Lablab purpureus was examined.
