The methanolic extracts of Lactarius deterrimus, Suillus collitinus, Boletus edulis, Xerocomus chrysenteron were analyzed for their antioxidant activities in different test systems namely beta-carotene/linoleic acid, DPPH free radical scavenging, reducing power and metal chelating activities in addition to their total phenolic and flavonoid contents. In beta-carotene/linoleic acid and DPPH systems, L. deterrimus and B. edulis showed the strongest activity patterns. Their activities were as strong as the positive controls. The reducing power of the species was excellent. Chelating capacity of the extracts was increased with the increasing concentration. On the other hand, B. edulis found to have the highest phenolic content. Total flavonoid content of S. collitinus found the superior to the other mushrooms.
对乳白红菇、黏盖牛肝菌、美味牛肝菌、金红绒盖牛肝菌的甲醇提取物在不同测试体系中的抗氧化活性进行了分析，这些体系包括β-胡萝卜素/亚油酸体系、DPPH自由基清除体系、还原能力和金属螯合活性，此外还测定了它们的总酚和黄酮含量。在β-胡萝卜素/亚油酸体系和DPPH体系中，乳白红菇和美味牛肝菌表现出最强的活性模式。它们的活性与阳性对照一样强。这些物种的还原能力极佳。提取物的螯合能力随浓度增加而增强。另一方面，发现美味牛肝菌的酚含量最高。黏盖牛肝菌的总黄酮含量高于其他蘑菇。
