| Abstract: | This paper studies the antioxidant compounds and antioxidant activity of anti-fatigue sport drink prepared with Rhodiola and other edible and medicinal vegetable herbs.The total flavonoid content of each herb extract as well as the prepared drink are evaluated.For antioxidant activity,the DPPH radical scavenging activity,reducing power and lipid peroxidation of the extracts are evaluated.The results indicate that the sport drink has high level of antioxidant compounds and activity.The total flavonoid is 3.13 mg/100 g,the reducing activity is 83.29 μg/mL and the DPPH scavenging activity is 49% in the concentrated liquid,separately.The results indicate the antioxidant drink may play the effect of dissipating sport fatigue. |
