In this study, antioxidative activities of aqueous extract of (BBE) in stabilizing of canola oil during storage at 20°C was evaluated. For this purpose, the total phenolic (TP), flavonoids (TFC), and tocopherol content (TTC) of the extract were determined and β-carotene bleaching system was used to assess the antioxidant efficacy of BBE. The amount of TP, TFC, and TTC in BBE indicated high antioxidant activity. So, different concentrations (0, 200, 800, and 1400 ppm) of BBE and butylatedhydroxyanisole (BHA; 100 ppm), were added to canola oil for 60 days at 20°C. Peroxide value (PV), carbonyl value (CV), Total polar compounds (TPC), acid value (AV), iodine values (IV), and conjugated dienes (CD) were employed to evaluate the BBE effect on canola oil stabilizing. Results indicated that 1,400 ppm of BBE exhibited stronger antioxidant activity in canola oil than BHA.

Sterols and triterpene alcohols exist in free and esterified forms in edible oils. To date, only few studies have determined the content of free or esterified sterols and triterpene alcohols using gas chromatography-flame ionization detection (GC-FID). In this study, analytical conditions were optimized using free and esterified sterol standards.

Introduction: Heavy metal soil pollution is a global issue that can be efficiently tackled through the process of phytoremediation. The use of rapeseed in the phytoremediation of heavy metal-contaminated agricultural land shows great potential. Nevertheless, its ability to tolerate heavy metal stress at the molecular level remains unclear.

Background/objectives: Dementia is not a single disease but an umbrella term that encompasses a range of symptoms, such as memory loss and cognitive impairments, which are severe enough to disrupt daily life. One of the most common forms of dementia is Alzheimer's Disease (AD), a complex neurodegenerative condition influenced by both genetic and environmental factors. Recent research has highlighted diet as a potential modifiable risk factor for AD.

Potassium, an essential inorganic cation, is crucial for the growth of oil crops like L. Given the scarcity of potassium in soil, enhancing rapeseed's potassium utilization efficiency is of significant importance. This study identified 376 potassium utilization genes in the genome of ZS11 through homologous retrieval, encompassing 7 functional and 12 regulatory gene families.
