We report the identification of the allelochemical 3-(1-oxo-3-phenylpropyl)-1,1,5-trimethylcyclo-hexane-2,4,6-trione, known as myrigalone A, from the fruits and leaves of Myrica gale. The structure of the compound was confirmed by high-resolution techniques (UV, MS and NMR analysis). The compound is phytotoxic towards classical plant species used for allelochemical assays and also against Fallopia x bohemica, a highly invasive plant. Application of either powdered dry leaves or dry fruits of M. gale also showed in vitro phytotoxic activity. We hypothesize that M. gale could be used as a green allelopathic shield to control Fallopia x bohemica invasion, in addition to its potential use as an environmentally friendly herbicide.
我们从杨梅的果实和叶子中鉴定出化感物质 3-(1-氧代-3-苯基丙基)-1,1,5-三甲基环己烷-2,4,6-三酮，称为杨梅酮 A。该化合物的结构通过高分辨率技术（UV、MS 和 NMR 分析）得到确认。该化合物对用于化感测定的经典植物物种以及高度入侵性植物 Fallopia x bohemica 具有植物毒性。应用杨梅的干叶粉或干果也显示出体外植物毒性活性。我们假设杨梅除了可以作为一种环保型除草剂使用外，还可以作为一种绿色化感屏蔽来控制 Fallopia x bohemica 的入侵。
