| Abstract: | The experiment studied the optimum conditions of sub-critical water using in the extrac-tion of lentinan.The results showed that the optimum conditions were as follows.The subcritical water temperature was 150 ℃,suitable ratio of solvent was 35 mL.g-1,the extraction time was 11 min,extraction times were 2 times.Under the conditions,the yield of lentinan was 15.7%.Comparing with the water extrac-tion method,the sub-critical water extraction could shorten the extraction time and improve the yield of lentinan. |
