https://www.selleckchem.com/products/anisomycin.html Up-regulation of key components of ascorbate-glutathione (AsA-GSH) cycle, the metabolic pathway that detoxify H2O2, was also observed in melatonin-treated cabbages. These findings suggest that melatonin-delayed postharvest leaf senescence of postharvest Chinese flowering cabbage may be mediated, at least in part, by maintaining ROS homeostasis through restraining RBOHs-catalyzed ROS production and enhancing the activity of ROS-scavenging system including major antioxidant enzymes and AsA-GSH cycle.Camellia kucha (Chang et Wang) Chang is a special tea in China, which is extremely bitter but beneficial for human health. However, there are no systematic studies on Kucha metabolites, especially those associated with bitterness. In this study, a non-targeted metabolomics approach based on UHPLC-LTQ-Orbitrap-MS was applied to comprehensively profile the characteristic metabolites of two Kucha cultivars by comparison with three common tea cultivars. A total of 90 differential metabolites were identified. Among them, eight key metabolites (theacrine, 2,4-dimethyl-1H-indole, EGCG, dihydrokaempferol, panasenoside, 3-cresotinic acid, 3-methylglutaconic acid, and L-histidine) were more abundant in Kucha than in the controls, most of which were positively correlated with bitterness. Furthermore, quantitative analysis of some important catechins and alkaloids by HPLC implied absolutely higher concentrations of EGCG and theacrine in Kucha, which was similar to the metabolomics results. These results will be contribute to future research on the bitter and nutritional properties of Kucha.The effects of fat/oil type (pork fat; sunflower seed, peanut, corn and flaxseed oils) and ethylcellulose (EC) concentration (8%, 10% and 12%) on the gel characteristic of pork batter were investigated in this study. Replacing pork fat in meat batter with organogels prepared with EC and vegetable oils obtained cooked batters with higher hardness,
