本研究以毛木耳子实体为研究对象，研究了子实体中蛋白提取物体内降血脂的活性。研究显示毛木耳的具有明显降低胆固醇的作用。研究方法：提取毛木耳子实体中蛋白类的物质，进行大鼠降血脂的研究。结果显示毛木耳蛋白提取物有明显降低血液中胆固醇、甘油三酯和低密度脂蛋白胆固醇的功效，降低率分别为28.4%、22.95%和42.14%，同时能够明显缓解高脂饮食引起的脂肪肝症状。由于毛木耳具有降血脂的功效可作为保健食品研发的原材料。

The hypolipidemic functions of Auricularia polytricha was investigated in this research. The results showed that Auricularia polytricha could decrease the cholesterol level significantly in vivo. The protein component was then extracted and its hypolipidemic function in vivo towards rats was studied. It was found that the protein extract of Auricularia polytricha could decrease the levels of cholesterol, triglycerides and low-density lipoprotein cholesterol in blood with the ratio of 28.4%, 22.95% and 42.14%, respectively. The protein extract also could relief the degree of fat liver. Auricularia polytricha protein extract could be applied in preparation of health supplement
