| Abstract: | Objective] To obtain the optimal extraction conditions for rutin from Morus alba L.leaf.Method] Using ethanol concentration,solid-to-liquid ratio,extraction time and extraction temperature as four factors and extraction rate of rutin as an indicator,the extraction conditions were optimized by orthogonal test based on single factor test.Result] The optimum extracting combination for rutin from mulberry leaf was A3B1C1D3.In other words,the mulberry leaf extracted with 60% ethanol as solid to liquid ratio of 1∶20 at 30 ℃ for 50 min was highest in yield with absorbance of 0.171.Conclusion] The optimal extraction process was obtained in this work,and this research provided reference for better development and application of Morus alba L. leaf. |
