Anti-fatigue effects of small-molecule oligopeptides isolated from Panax quinquefolium L. in mice
Abstract
American ginseng (Panax quinquefolium L.) was reported to have extensive biological activities and pharmaceutical properties. In most of the studies, the anti-fatigue effects of American ginseng are attributed to ginsenoside, and in only a few studies, they have been attributed to oligopeptides. Therefore, the aim of this study was to observe the anti-fatigue effects of small-molecule oligopeptides isolated from Panax quinquefolium L. (QOPs) in mice. At first, mice chosen for the study were randomly divided into four experimental groups; each group of mice was further divided into five subgroups: vehicle control group, whey protein group (450 mg per kg BW), and three groups of QOPs at different doses (225 mg per kg BW, 450 mg per kg BW, and 900 mg per kg BW). Test substances were given by gavage once a day for 30 days. QOPs can significantly prolong the forced swimming time, decrease the serum urea nitrogen (SUN) and blood lactate (BLA) levels, and increase the lactate dehydrogenase (LDH) activity and hepatic glycogen content. QOPs also markedly enhanced the superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) activity and attenuated the malondialdehyde (MDA) levels. Notably, QOPs enhanced the activity of succinate de...Continue Reading
