As the main metabolites of ginsenosides, 20(S, R)-protopanaxadiol (PPD(S, R)) and 20(S, R)-protopanaxatriol (PPT(S, R)) are the structural basis response to a series of pharmacological effects of their parent components. Although the estrogenicity of several ginsenosides has been confirmed, however, the underlying mechanisms of their estrogenic effects are still largely unclear. In this work, PPD(S, R) and PPT(S, R) were assessed for their ability to bind and activate human estrogen receptor α (hERα) by a combination of in vitro and in silico analysis.
Ginsenoside Rg1 augments oxidative metabolism and anabolic response of skeletal muscle in mice
The ginsenoside Rg1 has been shown to exert various pharmacological activities with health benefits. Previously, we have reported that Rg1 promoted myogenic differentiation and myotube growth in C2C12 myoblasts. In this study, the in vivo effect of Rg1 on fiber type composition and oxidative metabolism in skeletal muscle was examined.

Ameliorative effects of ginseng and ginsenosides on rheumatic diseases
Inflammation is a host-defensive innate immune response to protect the body from pathogenic agents and danger signals induced by cellular changes. Although inflammation is a host-defense mechanism, chronic inflammation is considered a major risk factor for the development of a variety of inflammatory autoimmune diseases, such as rheumatic diseases. Rheumatic diseases are systemic inflammatory and degenerative diseases that primarily affect connective tissues and are characterized by severe chronic inflammation and degeneration of connective tissues.

Nonsaponin fraction of Korean Red Ginseng attenuates cytokine production via inhibition of TLR4 expression
Ginsenosides of Korean Red Ginseng extracts (RGE) and its saponin components suppress secretion of inflammasome-mediating cytokines, whereas the nonsaponin fraction (NS) of RGE oppositely stimulates cytokine secretion. Although direct exposure of NS to macrophages in mice induces cytokine production, oral administration of NS has not been studied in inflammasome-related disease in animal models.

Endophytic Trichoderma citrinoviride isolated from mountain-cultivated ginseng (Panax ginseng) has great potential as a biocontrol agent against ginseng pathogens
Ginseng (Panax ginseng Meyer) is an invaluable medicinal plant containing various bioactive metabolites (e.g. ginsenosides). Due to its long cultivation period, ginseng is vulnerable to various biotic constraints. Biological control using endophytes is an important alternative to chemical control.

Evaluation of the gastroprotective effects of 20 (S)-ginsenoside Rg3 on gastric ulcer models in mice
Gastric ulcer (GU) is a common gastrointestinal disease that can be induced by many factors. Finding an effective treatment method that contains fewer side effects is important. 20 (S)-ginsenoside Rg3 is a kind of protopanaxadiol and has shown superior antiinflammatory and antioxidant effects in many studies, especially cancer studies. In this study, we examined the treatment efficacy of 20 (S)-ginsenoside Rg3 on GU.
