AbstractContext Panax ginseng C. A. Meyer (Araliaceae) is a tonic herb used in ancient Asia.Objective This study investigated the antifatigue effect of P. ginseng on chronic fatigue rats.Materials and methods Sprague-Dawley rats were divided into control, model and EEP (ethanol extraction of P. ginseng roots) (50, 100 and 200 mg/kg) groups (n = 8). The rats were subcutaneously handled with loaded swimming once daily for 26 days, except for the control group. The animals were intragastrically treated with EEP from the 15th day. On day 30, serum, liver and muscles were collected, and the PI3K/Akt/mTOR signalling pathway was evaluated.Results The swimming times to exhaust of the rats with EEP were significantly longer than that without it. EEP spared the amount of muscle glycogen, hepatic glycogen and blood sugar under the chronic state. In addition, EEP significantly (p

Panax ginseng C. A. Meyer (Araliaceae) is a tonic herb used in ancient Asia. This study investigated the antifatigue effect of P. ginseng on chronic fatigue rats. Sprague-Dawley rats were divided into control, model and EEP (ethanol extraction of P. ginseng roots) (50, 100 and 200 mg/kg) groups (n = 8). The rats were subcutaneously handled with loaded swimming once daily for 26 days, except for the control group. The animals were intragastrically treated with EEP from the 15th day. On day 30, serum, liver and muscles were collected, and the PI3K/Akt/mTOR signalling pathway was evaluated. The swimming times to exhaust of the rats with EEP were significantly longer than that without it. EEP spared the amount of muscle glycogen, hepatic glycogen and blood sugar under the chronic state. In addition, EEP significantly (p < 0.05) decreased serum triglycerides (1.24 ± 0.17, 1.29 ± 0.04 and 1.20 ± 0.21 vs. 1.58 ± 0.13 mmol/L) and total cholesterol (1.64 ± 0.36, 1.70 ± 0.15 and 1.41 ± 0.19 vs. 2.22 ± 0.19 mmol/L) compared to the model group. Regarding the regulation of energy, EEP had a positive impact on promoting ATPase activities and relative protein expression of the PI3K/Akt/mTOR pathway. Our results suggested that EEP effectively relieved chronic fatigue, providing evidence that P. ginseng could be a potential dietary supplement to accelerate recovery from fatigue.

The antifatigue effect of the tissue culture of Saussurea involucrata (TCSauI) KAR. et KIR. (Compositae) was investigated in mice on swimming time, hepatic glycogen content, serum lactic acid content, serum urea-nitrogen, and serum lactate dehydrogenase. The current study provides evidence that TCSauI has antifatigue activity, suggesting the potential of the tissue culture technique to substitute for wild S. involucrata (WSauI) in the pharmaceutical industry.
