Optimum Process for Extraction of Total Flavonoids from Castor Leaves by Orthogonal Test

Abstract:

Optimization of total flavonoid extraction from Castor leaves using orthogonal test methodology with the factors of ethanol concentration, extraction temperature,extraction time,solid/liquid ratio on the yield of total flavonoids were investigated.The results showed that optimum extracting conditions of total flavonoids from castor leaves were as follows: adding 1:40 g·mL^-1 of 30% alcohol and extracting for 30 min,extraction temperature 70°C. Under the optimal conditions, the maximal yield of flavonoids was of 1.81%.
