Nutritional quality and anti-fatigue effect of Hubei hybrid wolfberry thick pulp beverage
Hubei hybrid wolfberry was used to study its nutritional quality and anti-fatigue effect and compare with that of the commercially available northern wolfberry as the raw material of the thick pulp bev-erage.The effects of Hubei hybrid wolfberry drink on relieving physical fatigue were investigated by analyz-ing its nutritional quality and determining the exhaustion time of swimming with a load in mice.In the ani-mal experiments,the content of liver glycogen(LG),muscle glycogen(MG),blood lactic acid(BLA),blood urea nitrogen(BUN),malondialdehyde(MDA),superoxide dismutase(SOD),and glutathione re-ductase(GR)after exercise in mice after gavage of Hubei hybrid wolfberry thick pulp beverage at different dosage(4,8,12 mL/kg)were determined and compared with that of the blank group.The results showed that active substances including phenolics 175.44 μg/g,flavonoids 98.91 μg/g,proteins 1.90 mg/g,betaine 0.30 mg/mL,and Se 1.59 μg/kg in Hubei hybrid wolfberry thick pulp beverage were higher than that of commercially available wolfberry thick pulp beverage,and had better antioxidant activity.The results of an-imal experiments showed that the medium-dosage and high-dosage group(daily gavage at 8 and 12 mL/kg)of Hubei hybrid wolfberry thick pulp beverage effectively prolonged the exhaustion time of swimming with a load in mice,and both of them significantly improved the anti-fatigue effect on mice(P<0.05),1.66 times and 2.10 times more than that in the blank group.The high-dosage group(daily gavage at 12 mL/kg)was 1.32 times higher than that of the commercially available commercially available wolfberry thick pulp beverage group,and the difference was significant(P<0.05).After exercise,the content of MG and LG of mice in the high dosage group of Hubei hybrid wolfberry thick pulp beverage increased by 47.03%and 116.22%compared to the blank group,and the content of BLA,BUN,and MDA significant-ly decreased(P<0.05),and the activity of SOD and GR significantly increased(P<0.05),indicating that Hubei hybrid wolfberry thick pulp beverage has better anti-fatigue effect.It will provide a scientific ba-sis for mining the health effect of Hubei hybrid wolfberry and a new idea for developing functional foods for people with exercise fatigue.
