Abstract
|
|
|
|
Phellinus gilvus is a medicinal mushroom used that has been used in folk medicine in Asian countries for centuries. The aim of this study was to investigate the anti-xanthine oxidase, anti-cholinesterase, and anti-inflammatory activities of methanol (ME) and hot water (HW) extracts prepared from fruiting bodies of Ph. gilvus. ME and HW had good anti-xanthine oxidase (XO) activities compared to allopurinol, an inhibitor of xanthine oxidase. ME showed comparable and slightly lower inhibitory activity against acetylcholinesterase (AChE) and butyrylcholinesterase (BChE), respectively, than galanthamine, a standard AChE and BChE inhibitor. ME also showed a protective effect against glutamate-induced cytotoxicity at 40 mg/mL and 100 mg/mL in PC-12 cells. ME (0.5∼2.0 mg/mL) significantly inhibited nitric oxide (NO) production in RAW 264.7 murine macrophage cells stimulated with lipopolysaccharide (LPS). Carrageenan-induced hind-paw edema in rats was significantly reduced 2∼6 hr after treatment with 50 mg/kg of ME, which was comparable to administration of 5 mg/kg of indomethacin, the positive control. These results demonstrate that ME and HW of Ph. gilvus fruiting bodies possess good anti-xanthine oxidase, anti-cholinesterase, and anti-inflammatory activities.
