The extraction technology for the total saponin from the leaves of Dracaena cambodiana Pierre ex C, agn by enzymatic hydrolysis was studied. By means of enzymatic hydrolysis and extraction by ethanol, the optimum extraction technology was determined by single factor and orthogonal experiment, with the use of the extraction rate of the total saponin of the leaves of Dracaena cambodiana Pierre ex Gagn as the assessment index. The results showed that: the optimum conditions is, mass concentration of cellulase was 0.20 mg/ml, temperature was 50 ℃, pH is 5.0, time is 1.5 hour and solid-liquid ratio is 1 : 12, the extraction efficiency is 4.13% in this condition.
