食用块菌形态特征和抗氧化性能研究

Study on morphological character and antioxidant activity of edible truffle

对产于云南的块菌的形态特征进行了研究,观察了子实体、子囊孢子的形态,并将块菌的水提取液和醇提取液进行了清除DPPH自由基、清除超氧负离子自由基、清除羟基自由基的抗氧化性能实验。结果表明,块菌有大而壁厚的子囊孢子,人工培养时不易萌发。块菌的水提取液和醇提取液都有较好的抗氧化性能,醇提取液的抗氧化性能优于水提取液。

The morphological character of edible truffle was studied through the observation of fruiting body and ascospore in this paper, and its antioxidant activity was also studied by testing cleaning DPPH · free radical, superoxide radical and hydroxy radical with the water extract and the alcohol extract of truffle.The result showed that truffle ascospore had large and thick wall,which prevented from its germination in artificial culture.The water extract and the alcohol extract of truffle both have better antioxidant activity,and the alcohol extract is superior to the water extract in antioxidant activity.
