Abstract: The optimum conditions of enzymolysis and extraction process by orthogonal design were studied. The results showed that the optimum conditions of ginsenosides extraction technique were as follows: First, laccase treatment: 1g Panax ginseng was put into 15ml (92U/ml) laccase with temperature 30℃, pH value 3.5 and fermenting time 1.5h. Then, in comparison with water-extraction, the enzyme-based extraction rate of ginsenosides is increased by 70.9%.
