  • Optimized synthesis of 2-substituted 1-halocyclopropane-1-carboxylic acids
    作者:A. A. Zagidullin、A. V. Zorin、V. V. Zorin

    日期:2016.10
    gem-dibromocyclopropanes with n-butyllithium in THF under argon at–78°С followed by purging the reaction mixture with dry CO2 was used to synthesize cis- and/or trans-1-halocyclopropane-1-carboxylic acids in 30–56% yields. The yields of the target products could be increased to 76–83% by the addition of an equimolar amount of LiCl to the reaction mixture. The highest salt effect was obtained with lithium

  • Modulation of Actinidia arguta fruit ripening by three ethylene biosynthesis inhibitors
    作者:Yuehua Wang、Fangxu Xu、Xuqiao Feng、Roseline Love MacArthur
    DOI:10.1016/j.foodchem.2014.10.044
    日期:2015.4
    The purpose of this study was to investigate the effect of postharvest application of 1-methylecyclopropene (1-MCP), 1-pentylcyclopropene (1-PentCP) and 1-octylcyclopropene (1-OCP), two structural analogues of 1-MCP, on Actinidia arguta (Siebold et Zucc.) Planch. ex. Miq. Fruit post-harvest ripening and antioxidant activity. The results showed that these two structural analogues, just as 1-MCP, exerted their effect in a concentration-dependent manner. The most effective concentration of 1-MCP, 1-PentCP or 1-OCP treatment was 1.2 mu l L-1, 1.2 mu l L-1 and 0.8 mu l L-1, respectively. But, 0.8 mu l L(-1)1-OCP was found to be more potent in postponing the appearances of respiration rate peak and ethylene production peak, delaying the softening and weight loss, suppressing the activities of ACC synthase (ACS) and ACC oxidase (ACO), maintaining higher glutathione (GSH) content, activities of glutathione reductase (GR) and ascorbate peroxidase (APX), though slightly inferior to 1.2 mu l L-1 1-MCP.
