This study confirms the anti-obesity effect of the ethyl acetate fraction of (DRE), a member of Hamamelidaceae, that naturally grows on Jeju Island, on adipocyte differentiation in 3T3-L1 cells. This study further demonstrated that DRE exhibits anti-obesity effects in C57BL/6 obese mice. The degree of adipocyte differentiation was determined using Oil red O stain; results indicated a decrease in fat globules, which was dependent on DRE concentration, when pre-adipocytes were treated with differentiation-inducing agents. In addition, this significantly reduced the expression of the adipogenic transcription factor and related genes. C57BL/6 obese mice treated with DRE showed a lower rate of body weight gain than the high-fat diet (HFD) group mice. Further, the level of serum triglyceride in the DRE treatment group was lower than that in the HFD group. The findings show that DRE are capable of suppressing adipocyte accumulation; therefore, DRE may represent a promising source of functional materials for the anti-obesity.

In this study, antiulcer activity of ethanolic extract and solvent fractions of the aerial part of was investigated using ethanol-induced model of gastric ulceration in rats. The results showed that ethyl acetate, non-polar components and diethyl ether fractions have a remarkable antiulcerogenic activity; because they exhibited control-ulcer protection by 85.2%, 77.

The bacterial reverse mutation test is essential for identifying the mutagenic potential of chemicals. The solubility of the test substance is vital for achieving the recommended assay concentration. Preferred solvents like dimethyl sulfoxide and water are chosen for their compatibility and historical data.

Instability in initial abiotic factors of open solid-state fermentation systems can significantly alter 's flavor profile, but the mechanisms governing microbial interactions and flavor formation remain unclear. This study comprehensively monitored changes in abiotic factors, microbial communities, and flavor profiles across two distinct fermentation processes in a distillery, which differed significantly in their management of initial abiotic factors. Our results revealed significant differences in abiotic factors between the two groups, including moisture, ethanol, acidity, glucose, and organic acid levels.

Background: Functional foods and dairy products are gaining global attention due to their nutritional value and health-promoting characteristics. Lactic acid bacteria (LAB) are one of the promising components included in these products, thanks to their probiotic properties and ability to produce bioactive compounds such as bacteriocins. On the other hand, ectomycorrhizal wild mushrooms (truffles) are known for their ethnomycological importance.
