    “…Nitrogen-containing heterocycles are an important class of antioxidants, and their reactivity and selectivity in hydrogen atom reactions have attracted significant interest from chemists. In this work, the kinetics of hydrogen atom transfer reactions from C(sp(3))–H bonds of 28 nitrogen-containing heterocycles, oxygen-containing heterocycles, alicyclic amines and cycloalkanes, which were denoted as XH, to the CumO˙ radical, were investigated. …”

    “…The analysis method relied on inductively coupled plasma-optical emission spectrometry for major nutrient elements and inductively coupled plasma-mass spectrometry for trace and toxic elements and complied with the Association of Official Analytical Chemists (AOAC) guidelines. Kimchi cabbage leaves and roots featured high contents of K, B, and Be, while the contents of all toxic elements in all samples were below the WHO-stipulated threshold values and therefore did not pose any health risks. …”
