Abstract

|
The biological and antioxidative activity of Phellinus linteus extracts from gradient ethanol concentrations were examined. The phenol contents of Phellinus linteus (28.36 mg/100ml) was higher in the 80% ethanol extracts than other extracts. Electron donation ability on DPPH of 80% and 90% ethanol extracts (94.12% and 94.14% inhibition) from Phellinus linteus were the highest. The antioxidant activity against water soluble materials of Phellinus linteus ethanol extracts showed totally high inhibition rates above 80%, especially in 80% and 90% ethanol extracts, they showed each 94.12% inhibition and 94.14% inhibition. The inhibition against ABTS [2,2azinobis(3-ethylbenzothiazoline-6- sulfonic acid)] radical decolorization of 80% ethanol extracts was the highest as 96.2%. The antioxidant protection factor (PF) against lipid soluble materials was the highest in 80% ethanol extracts as 1.69 PF, and TBARS of 80% and 90% ethanol extracts were lower as 1.15 × 100 μM and 1.21 × 100 μM than control (1.95 × 100 μM). Angiotensin converting enzyme and xanthine oxidase inhibitory activity of 80% ethanol extracts from Phellinus linteus was higher as 95.10%, 85.07% than other extracts. The results to analized of simple phenolic compounds of Phellinus linteus ethanol extrcts with HPLC showed that they were procatecuic acid, caffeic acid and coumaric acid.
