Ailanthone is a quassinoid allelochemical produced by the tree Ailanthus altissima (commonly known as tree of heaven).[1] It is a key agent behind the tree's strong allelopathic effects, which inhibit the growth of competing plants by suppressing seed germination and disrupting root elongation.[2][3][4] Native to China, Ailanthus altissima has become one of the worst invasive species in North America and Europe, where ailanthone is known to contribute significantly to its competitive spread.[3][5][6]
