This paper introduced two processes continuous reflux extraction and a continual reflux extraction of diosgenin. Making acomparison between the two methods, we found that the relation beteen the residue(Wn) of diosgenin in materials and time(n) canbe described for the continual reflux extractive process by the folllowing equation: Wu=WO’ A’ and the residue(Wt) of diosgenin inmaterials and time(t) can be described for the process by the following equation: Wt=A.(A. B+B)t-1 W0 It shows the recovery rateof the continual reflux extraction is better. The result of extraction indicated that the continual reflux extractive method enhancedrecovery Fate,and saved the time of extraction also.
