    Abstract: An herbicidal substance, elemicin, purified from Asarum sieboldii Miq. and a preparation method thereof are provided to serve a novel herbicide having different chemical structure compared with conventional herbicides, so that it will be a lead compound for development of new herbicides. The method for preparing the elemicin having herbicidal effects purified from Asarum sieboldii Miq. comprises the steps of: (a) extracting Asarum sieboldii Miq. with methanol and drying the extract; (b) dissolving the methanol extract of Asarum sieboldii Miq. in hexane to prepare a hexane fraction; (c) subjecting the hexane fraction to column chromatography using hexane-ethylacetate-methanol solution(5:1:0.1 v/v/v) to obtain HB fraction; (d) subjecting the HB fraction to column chromatography using hexane-ethylacetate-methanol solution(9:1:0.5 v/v/v) to obtain HBB fraction; (e) subjecting the HBB fraction to column chromatography using hexane-ethylacetate solution(5:5 v/v) to obtain HBBA fraction; and (f) subjecting the HBBA fraction to affinity column chromatography using methanol-acetonitrile solution(9:1 v/v) to obtain HBBAA fraction.

    Abstract translation: 从Asarum sieboldii Miq纯化的除草物质elemicin 并提供其制备方法以用于与常规除草剂相比具有不同化学结构的新型除草剂，从而它将是用于开发新除草剂的铅化合物。 从Asarum sieboldii Miq。制备具有除草效果的elemicin的方法。 包括以下步骤：（a）提取Asarum sieboldii Miq。 用甲醇和干燥提取物; （b）溶解Asarum sieboldii Miq的甲醇提取物。 在己烷中制备己烷级分; （c）使用己烷 - 乙酸乙酯 - 甲醇溶液（5:1:0.1v / v / v）对己烷部分进行柱层析，得到HB级分; （d）使用己烷 - 乙酸乙酯 - 甲醇溶液（9:1:0.5v / v / v）对HB馏分进行柱层析，得到HBB馏分; （e）使用己烷 - 乙酸乙酯溶液（5:5v / v）对HBB馏分进行柱层析，得到HBBA馏分; 和（f）使用甲醇 - 乙腈溶液（9:1v / v）对HBBA级分进行亲和柱层析，得到HBBAA级分。
