Abstract
The extraction of coarse saponins from the older stems of Asparagus Officinalis was optimized by employing Taguchi Robust Experimental Design.The optimum extraction conditions were as follows: concentration of ethanol,90%(V∶V);temperature,75 ℃;ratio of material to ethanol solution,1∶15(W∶V);extraction time,2.5 h;and the extraction was executed twice.
