Summary: This study investigated the effect of Grape Seed Proanthocyanidin (GSP) on fat metabolism and adipocytokines in obese rats. The results showed that GSP supplementation reduced weight, abdominal fat weight, glucose, cholesterol, triglycerides, low-density lipoprotein, cyclooxygenase-2, and interleukin-6 levels in adipose tissue. Moreover, GSP addition caused adipocyte crumpling in vitro and reduced the mRNA expression of COX-2, LEP, and TNF-alpha in adipocytes. These findings provide evidence for exploring the role of GSP in the prevention and treatment of obesity and related diseases.

Summary: The aim of this comparative research was to determine the chemical composition, antioxidant and antibacterial activities of the methanolic extracts and essential oils (EOs) of Artemisia absinthium aerial parts from five different regions (Bizerte, Zaghouan, Kasserine, Gabes and Tozeur). The results showed that the polyphenol and flavonoid contents varied among the studied regions, with the highest contents observed in Zaghouan. The methanolic extract of Zaghouan exhibited the highest scavenging ability of DPPH. The EOs from different regions of A. absinthium showed interesting inhibitory effects on both Gram-negative and Gram-positive bacteria, with the EO from Zaghouan showing the strongest inhibitory effect against Escherichia coli. These findings suggest that the north regions have a high potential for selecting A. absinthium varieties rich in bioactive compounds.

Summary: The oak forest in Tunisia, mainly located in the north-west, is of great ecological and socio-economic importance. It provides income for the local population, contributes to soil conservation, and is home to diverse flora and fauna. However, this forest is threatened by various pressures, such as browsing and competition for resources. This study focused on the intra and interspecific variability of two oak species, Quercus suber and Quercus canariensis, and found that leaf morphology and water use efficiency are important factors for choosing the right species for reforestation.

Summary: This study aimed to examine the effectiveness of five green solvents (2-methyltetrahydrofuran, cyclopentyl methyl ether, p-cymene, d-limonene, and ethanol) in replacing n-hexane for sesame seed oil extraction. Both cyclopentyl methyl ether and 2-methyltetrahydrofuran yielded higher crude yields than n-hexane. The fatty acid composition of sesame seed oils remained consistent across all solvent systems, with high concentrations of oleic acid and linoleic acid. Cyclopentyl methyl ether and 2-methyltetrahydrofuran extracted the highest levels of sterols, tocopherols, and total phenols, and exhibited the strongest antioxidant and anti-inflammatory properties. These findings suggest that cyclopentyl methyl ether and 2-methyltetrahydrofuran are promising alternatives for sesame seed oil extraction.
