Abstract

The phenolic and flavonoid contents and composition and the antioxidant ability in Hericium erinaceus, Ganoderma lucidum, and Agrocybe aegerita under selenium (Se) addition to growth medium were studied. The contents of total Se in fruiting bodies of controls (0 mM of Se) were 4.58 (A. aegerita), 8.53 (G. lucidum), and 14.29 (H. erinaceus) mg kg^–1 dry weight (DW), and was significantly increased by Se enrichment of substrate. The total phenolics in fruiting bodies of controls of H. erinaceus, G. lucidum, and A. aegerita were significantly lower (17.10, 28.11, and 16.05 mg of gallic acid equivalent (GAE)/g of extract, respectively) than for Se-rich mushrooms (26.29, 40.29, and 20.07 mg GAE/g of extract, respectively). Total flavonoid content for H. erinaceus, G. lucidum, and A. aegerita increased after Se supplementation from 368.6 to 445.6, 469.9 to 627.7, and 318.1 to 393.9 μg g^–1 of extract, respectively. The results show that the mushrooms have superior antioxidant properties after Se addition, because the scavenging ability on 2,2-diphenyl-1-picrylhydrazyl (DPPH) radicals was improved.
