The news correspondents obtained a quote from the research from NARO, "The active dichloromethane extract was subjected to liquid-liquid partitioning, and active fractions were further separated by normal-phase column chromatography and normal-phase high-performance liquid chromatography (HPLC). Nepodin (3) and emodin (4) were isolated from two fractions with strong toxicities against S. iniae. A chloroform fraction was further separated by normal-phase column chromatography to yield two active fractions against F. columnare , and these fractions contained chrysophanol (1), physcion (2), and nepodin (3)."
According to the news reporters, the research concluded: "Compound 1 had strong activity, and compound 3 had moderate activity against F. columnare , while compounds 2 and 4 were not toxic at the concentrations tested."
