Objective: Ellagic acid is used in traditional medicine for the treatment of lipid disorders. In this study, the effects of ellagic acid on key regulators of lipid metabolism, and histopathological alterations in aged liver were examined.
Methods: A total of 21 male Wistar rats were divided into three groups, including young control, old control, and old ellagic acid. After one month of treatment with ellagic acid, the expression levels of hepatic SIRT1, AMPK, SREBP-1c, PPAR-α, and phosphorylated AMPK (p-AMPK) were evaluated. The levels of several serum biochemical factors, and hepatic triglyceride, and cholesterol contents were assessed.
Results: Ellagic acid elevated the levels of SIRT1, p-AMPK, and PPAR-α and reduced SREBP-1c level in the liver of old rats. It decreased triglyceride and cholesterol contents in the aged liver and improved histopathological changes.
Conclusions: The results demonstrated that ellagic acid can exert protective effects against hepatic lipid metabolism disorders induced by ageing.

This study investigates the antimalarial potential of extracts and compounds from various plants used in traditional Korean medicine, in response to the increasing resistance of to standard treatments such as chloroquine and artemisinin. The antimalarial activity screening was conducted on 151 extracts, identifying the top seven candidates, including (50% ethanol and 100% methanol extract), , (hot water and 50% ethanol extract), , and . Among these, was identified as the top priority for further analysis due to its high antimalarial activity and high yield of bioactive compounds.

Mancozeb (MZ), an EBDC fungicide, has been found to contaminate agricultural products and cause male reproductive toxicity. The phytochemical compounds of white petal extract (WNPE) and its effects on metabolomic profiles and reproductive function in male rats poisoned with MZ were investigated. Seventy-two mature male Wistar rats were divided into nine groups ( = 8) and, for 30 days, were gavaged with WNPE at doses of 0.

Oxidative stress (OS), generated by the overrun of reactive species of oxygen and nitrogen (RONS), is the key cause of several human diseases. With inflammation, OS is responsible for the onset and development of clinical signs and the pathological hallmarks of Alzheimer's disease (AD). AD is a multifactorial chronic neurodegenerative syndrome indicated by a form of progressive dementia associated with aging.

The sustainable use of pomegranate peel, a by-product of the food industry, is gaining importance in developing pharmaceutical bio-inputs, aligning with circular economy practices and waste reduction. This study explores the application of dry crude pomegranate peel extract (PPE) as a bio-input for medicinal gels with wound healing properties. PPE was extracted via percolation in ethanol and freeze-dried.
