Two new triterpenoid saponins celosin I (1) and celosin II (2) were isolated from the seeds of Celosia argentea L. (Amaranthaceae). The structures of the two new compounds were elucidated based on chemical analysis and spectral methods (IR, 1-D and 2-D NMR, ESI-MS, HR-ESI-MS). They exhibited significant hepatoprotective effect on carbon tetrachloride-induced and N,N-dimethylformamide-induced hepatotoxicity in mice.

Deciphering the biosynthetic pathway of triterpene saponins in Prunella vulgaris.
Plant J
January 2025
College of Horticulture, Bioinformatics Center, Academy for Advanced Interdisciplinary Studies, Nanjing Agricultural University, Nanjing, 210095, China.
The traditional Chinese medicinal plant Prunella vulgaris contains numerous triterpene saponin metabolites, notably ursolic and oleanolic acid saponins, which have significant pharmacological values. Despite their importance, the genes responsible for synthesizing these triterpene saponins in P. vulgaris remain unidentified.

Context: The decline in ovarian reserve is a major concern in female reproductive health, often associated with oxidative stress and mitochondrial dysfunction. Although ginsenoside Rg1 is known to modulate mitophagy, its effectiveness in mitigating ovarian reserve decline remains unclear.
Objective: To investigate the role of ginsenoside Rg1 in promoting mitophagy to preserve ovarian reserve.
Effects of Astragaloside IV and Formononetin on Oxidative Stress and Mitochondrial Biogenesis in Hepatocytes.

Over-accumulation of reactive oxygen species (ROS) causes hepatocyte dysfunction and apoptosis that might lead to the progression of liver damage. Sirtuin-3 (SIRT3), the main NAD+-dependent deacetylase located in mitochondria, has a critical role in regulation of mitochondrial function and ROS production as well as in the mitochondrial antioxidant mechanism. This study explores the roles of astragaloside IV (AST-IV) and formononetin (FMR) in connection with SIRT3 for potential antioxidative effects.

Background: Triple-negative breast cancer (TNBC) is an aggressive subtype with limited treatment options and high resistance to chemotherapy. Doxorubicin is commonly used, but its efficacy is limited by variable sensitivity and resistance. Bacopaside II, a saponin compound, has shown anti-cancer potential.
