Antioxidant capacities, phenolic compounds and polysaccharide contents of 49 edible macro-fungi.
Summary of "Antioxidant capacities, phenolic compounds and polysaccharide contents of 49 edible macro-fungi."
Edible macro-fungi are widely consumed as food sources for their flavors and culinary features. In order to explore the potential of macro-fungi as a natural resource of bioactive compounds, the antioxidant properties and polysaccharide contents of 49 edible macro-fungi from China were evaluated systematically. A positive correlation between antioxidant capacity and total phenolic content indicated that phenolic compounds could be main contributors of antioxidant capacities of these macro-fungi. Furthermore, many bioactive compounds such as gallic, homogentisic, protocatechuic, and p-hydroxybenzoic acid were identified and quantified. The macro-fungi species Thelephora ganbajun Zang, Boletus edulis Bull., Volvariella volvacea Sing, Boletus regius Krombh, and Suillus bovinus Kuntze displayed the highest antioxidant capacities and total phenolic contents, indicating their potential as important dietary sources of natural antioxidants.

Medical and Biotech [MESH] Definitions
Beta-tocopherol
A natural tocopherol with less antioxidant activity than alpha-tocopherol. It exhibits antioxidant activity by virtue of the phenolic hydrogen on the 2H-1-benzopyran-6-ol nucleus. As in GAMMA-TOCOPHEROL, it also has three methyl groups on the 6-chromanol nucleus but at different sites.
Gamma-tocopherol
A natural tocopherol with less antioxidant activity than ALPHA-TOCOPHEROL. It exhibits antioxidant activity by virtue of the phenolic hydrogen on the 2H-1-benzopyran-6-ol nucleus. As in BETA-TOCOPHEROL, it also has three methyl groups on the 6-chromanol nucleus but at different sites.
Alpha-tocopherol
A natural tocopherol and one of the most potent antioxidant tocopherols. It exhibits antioxidant activity by virtue of the phenolic hydrogen on the 2H-1-benzopyran-6-ol nucleus. It has four methyl groups on the 6-chromanol nucleus. The natural d form of alpha-tocopherol is more active than its synthetic dl-alpha-tocopherol racemic mixture.
Quercetin
A flavonol widely distributed in plants. It is an antioxidant, like many other phenolic heterocyclic compounds. Glycosylated forms include RUTIN and quercetrin.
Lentinan
Polysaccharide isolated from the edible mushroom LENTINULA EDODES. The exact composition is unknown.
