Abstract
Phellinus spp. have historically been used as traditional medicines to treat various diseases owing to their antioxidant, antitumor, and antidiabetic activities. Polysaccharides exhibit antidiabetic activity. In the present study, the polysaccharide contents of four Phellinus strains were compared. Phellinus igniarius QB72 possessed higher polysaccharide production, stronger 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging, and α-amylase inhibitory activity. The three polysaccharides were sequentially extracted and partially purified from the fermentation mycelia using hot water, 1 % (NH4)2C2O4, and 1.25 M NaOH. Hot water extract polysaccharides exhibited higher DPPH radical scavenging and strong inhibitory activity against α-amylase with an IC50 value of 6.84 ± 0.37 mg/mL. The carbohydrate content of A1 (approximately 17457 Da) was approximately 88.28 %. The α-amylase inhibitory activity IC50 was decreased (3.178 ± 0.187 mg/mL) after DEAE water elution. P. igniarius QB72 hot-water extracts of partially purified polysaccharides have great potential as α-amylase inhibitors in food and medication-assisted additives.

Abstract
To fully utilize Phellinus igniarius fermentation mycelia, the present study investigated the in vitro antioxidant and α-amylase inhibitory properties of four Ph. igniarius strains. Organic solvents were used to extract fatty acids, phenolics, and flavonoids from the selected mushrooms. The composition and bioactivity of the extracts were evaluated. The lipid yield obtained using petroleum ether (7.1%) was higher than that obtained using 1:1 n-hex-ane+methanol (5.5%) or 2:1 dichloromethane+methanol (3.3%). The composition and relative content of saturated and unsaturated fatty acids in the petroleum ether extract were higher than those in other solvent extracts. Furthermore, ethyl acetate extracts had higher flavonoid and phenolic content and better antioxidant activity than other extracts; however, the 70% ethanol extracts had the best α-amylase inhibitory activity. The supernatant from the ethanol precipitation of aqueous and 1% (NH4)2C2O4 extracts could also be biocompound sources. This comparative study is the first highlighting the in vitro antioxidant and α-amylase inhibitory properties of the four strains of Ph. igniarius extracts prepared using different organic solvents, which makes the investigated species and extracts promising for biological application.
