Background & Objectives: Several biological activities of total saponins of Radix notoginseng (TSRN), a traditional Chinese medicine, have been reported. The present study was carried out to investigate anti-fatigue activity of TSRN in male Kunming mice.
Methods: Mice were divided into four groups. The first group designated as control group was administered with distilled water by gavage every day. The second, third and fourth groups designated as TSRN treatment groups were administered with TSRN of 20, 40 and 80 mg/kg body weight/day, respectively. The treatment continued for 28 days. Exhaustive swimming time, blood lactate and tissue glycogen contents of mice after swimming were determined.
Results: TSRN extended exhaustive swimming time of mice, effectively delayed the increase of lactate in the blood, as well as increased the tissue glycogen contents.
Interpretation & Conclusions: TSRN showed promising anti-fatigue activity in animal model. However, further study is needed to elucidate the mechanism of the effect of TSRN on fatigue.

Objectives: This study aimed to clarify the effect of lactic acid bacteria-fermented corn protein hydrolysate (FCH) on fatigue in mice and explore the connection between fatigue-related indicators and intestinal microbial flora.
Methods: The fatigue model of mice was constructed by exercise endurance experiment. The anti-fatigue level of FCH was evaluated by measuring physiological and biochemical indexes in mouse serum, liver and skeletal muscle.

Ethnopharmacological Relevance: Pseudostellaria heterophylla (Tài Zǐ Shēn, TZS) is a traditional Chinese medicine with spleen and qi benefits. Its immunomodulatory, anti-fatigue, anti-stress, and lipid metabolism regulation effects have been clinically confirmed, but its role in meibomian gland dysfunction (MGD) is still unclear.
Aim Of The Study: This study aims to investigate the effect and mechanism of action of TZS in treating MGD.

It has been well documented that a number of polysaccharides with potent free-radical scavenging capability possess notable anti-fatigue activity. Interestingly, recent evidence also suggested mixed polysaccharides derived from multiple sources may yield augmented bioactivities compared to the polysaccharides from a single source. Therefore, in the current study, we investigated the anti-oxidant and anti-fatigue activities of a blend of polysaccharides isolated from three mushrooms.

This comprehensive review explores the biological functions of seed proteins and peptides, highlighting their significant potential for health and therapeutic applications. This review delves into the mechanisms through which perilla peptides combat oxidative stress and protect cells from oxidative damage, encompassing free radical scavenging, metal chelating, in vivo antioxidant, and cytoprotective activities. Perilla peptides exhibit robust anti-aging properties by activating the Nrf2 pathway, enhancing cellular antioxidant capacity, and supporting skin health through the promotion of keratinocyte growth, maintenance of collagen integrity, and reduction in senescent cells.
