ABSTRACT
Objectives:
This study aimed to evaluate the effect of Wongisaengmaek-san (extracted with water or 50% ethanol) on antioxidative activity and recovery of fatigue induced by weight-loaded forced swimming exercise.

Methods :
Antioxidant activity of Wongisaengmaek-san was evaluated in terms of total amount of polyphenol, 1,1-diphenyl-2-picrylhydroxyl (DPPH) radical scavenging activity and xanthine oxidase inhibition. The anti-fatigue effect of Wongisaengmaek-san was investigated using an acute weight-loaded forced swimming test by monitoring swimming test times and blood biochemical parameters creatinine, BUN, lactic acid dehydrogenase (LDH), free fatty acid (FFA) and lactic acid (LA).

Results:
1. 50% EE (ethanol extract) had 2.3 times higher amount of total polyphenol compared to water extract. 2. It was identified that 50% ethanol extract showed enhancement of xanthine oxidase inhibition and DPPH scavenging effect in vitro. 3. According to anti-fatigue effect in the scale of 5% weight loaded mouse swimming test, both water and 50% ethanol extract showed significant improvement of swimming time elongation respectively, and 50% ethanol extract induced a more positive result. 4. After swimming for 1% weight-loaded mouse, water extract and 50% ethanol showed significant anti-fatigue effect with manifestation of blood sampling among both of the intervention; 50% ethanol extract showed a greater result.

Conclusions:
50% ethanol extract of Wongisaengmaek-san has more effective antioxidant activity and anti-fatigue than water extract.
