臭椿根水提液对萝卜具有化感作用。CV.“Saxa”），花园水芹（独行菜（Lepidium sativurri L.），和马齿苋（Portulaca oleracea L.）种子一个面向生物测定的活性提取物，色谱馏分，和化合物的纯化表现出剂量依赖性的活性测试种子的发芽和胚根生长，萝卜种子是最敏感的化感物质。已分离出活性化合物：ailanthone、ailanthinone、chaparrine和ailanthinol B（苦木素衍生物）;生物碱1-甲氧基canthin-6-酮无活性。抑制活性最大的化合物是椿酮。所获得的数据表明，天堂树根提取物或其活性成分可能用作天然除草剂。
The aqueous root extract of Ailanthus altissima showed allelopathic activity against radish (Raphanus sativus L. cv. "Saxa"), garden cress (Lepidium sativurri L.), and purslane (Portulaca oleracea L.) seeds. A bioassay-oriented purification of active extracts, chromatographic fractions, and compounds demonstrated dose-dependent activity on germination and radicle growth of test seeds; radish seed was the most sensitive to allelochemicals. Active compounds have been isolated: ailanthone, ailanthinone, chaparrine, and ailanthinol B (quassinoid derivatives); the alkaloid 1-methoxycanthin-6-one is not active. The compound with greatest inhibitory activity is ailanthone. The data obtained suggest a possible use of tree-of-heaven root extracts or of its active constituents as natural herbicides.
