    Product Description

    Cochlioquinone is a sesquiterpene metabolite originally isolated from C. miyabeanus.1 It is a phytotoxin that inhibits root growth of finger millet (E. coracana) and rice plants (O. sativa) by 59.9 and 51.7%, respectively, when used at a concentration of 100 ppm.2 Cochlioquinone B inhibits NADH oxidase and NADH-2,3-dimethoxy-5-pentyl-1,4-benzoquinone reductase from bovine heart mitochondria.3
