Pfaffia paniculata is a commercialized dietary supplement used as the substitute for the Asian ginseng in Brazil. We conducted the systematic isolation of the EtOAc fraction with anti-inflammatory effect and two new triterpenoids, along with 26 known compounds were characterized by means of MS and NMR analysis. Interestingly, the new compound 1 is the first seco-ring triterpenoid reported in the Pfaffia genus. Furthermore, among the known compounds, 14 and 15 exhibited anti-inflammatory activity in Caco-2 cells, but two new compounds showed no anti-inflammatory.

Antipsychotic medications are used to treat a psychological condition called 'Schizophrenia'. However, its long-term administration causes irregular involuntary motor movements, targeting the orofacial regions. Glycyrrhizic acid (GA) is a naturally occurring triterpene saponin glycoside obtained from the roots of the Glycyrrhiza glabra (liquorice) plant and well known for its antioxidant, antiapoptotic and neuroprotective abilities.

Soybean (Glycine max) is a leguminous crop cultivated worldwide that accumulates high levels of isoflavones. Although previous research has often focused on increasing the soybean isoflavone content because of the estrogen-like activity of dietary soy in humans, the rapidly increasing demand for soybean as a plant-based meat substitute has raised concerns about excessive isoflavone intake. Therefore, the production of isoflavone-free soybean has been anticipated.

Depression is one of the most common neurological diseases, which imposes a substantial social and economic burden on modern society. The purpose of this study was to explore the mechanism of total ginsenoside ginseng root (TGGR) in the treatment of depression through a comprehensive strategy combining network pharmacology, transcriptomics, and in vivo experimental validation. The Traditional Chinese Medicine Systematic Pharmacology (TCMSP) database and literature were used to collect the main components and targets of TGGR.
