Extraction Process Optimization of Total Alkaloid from Actinidia arguta

To study on optimal conditions for extracting the higher content of total alkaloid from Actinidia arguta fruits, the effects of ethanol concentration, temperature, time and solid-liquid ratio on extraction efficiency total alkaloid were explored. The results showed that the optimum extraction conditions included 70% ethanol as extracting solution, temperature on 60C, extraction time by 20 min, ratio of solid- liquid on 1:30 (g/mL). By this method, the total alkaloids of Actinidia arguta fruits were extracted to 1.021 mg/g. This experiment of extraction method is simple and easy to operate. It was improved the extraction yield of the total alkaloid extraction from Actinidia arguta fruits.
