以紫陀螺菌为对象,研究其子实体的化学成分及其抑制肿瘤细胞增殖活性。采用溶剂提取、柱层析和高效液相色谱等方法分离纯化化学成分,通过核磁共振和质谱技术鉴定单体化合物结构,运用结晶紫法评价单体化合物抑制肿瘤细胞增殖活性。从乙酸乙酯提取物中共分离鉴定6个单体化合物,分别为(22E,24R)-麦角甾-5,7,22-三烯-3β-醇(1)、3β,5α-二羟基-(22E,24R)-麦角甾-7,22-二烯-6-酮(2)、(22E,24R)-麦角甾-7,22-二烯-3β,5α,6β-三醇(3)、吲哚-3-甲酸甲酯(4)、4,4-二甲基-1,7-庚二酸(5)和(8E,10E)-12羰基十八碳-8,10-二烯酸(6),其中化合物1为主要成分,相对含量为23.8%。活性测试结果表明3对人乳腺癌细胞株MCF-7 细胞、人胰腺癌细胞株PANC-1细胞和人乳腺癌细胞株MDA-MB-231细胞具有微弱的细胞增殖抑制活性。本研究首次报道了紫陀螺菌化学成分,对深入挖掘其在健康领域中的开发价值具有重要意义。"/>template{display:none;}.mag-rich-xref-fn { cursor: pointer;}//长视频$(document).ready(function(){if($("#showLongArticleVideo") && $("#showLongArticleVideo").length && $("#showLongArticleVideo").length>0){mag_ajax_update({ele_id:'showLongArticleVideo',url:mag_currentQikanUrl() + "/CN/article/showLongArticleVideo.do?id="+$("#articleId").val()});}});//可视化图谱$(document).ready(function(){if($("#showArticle_knowledgeMap") && $("#showArticle_knowledgeMap").length && $("#showArticle_knowledgeMap").length>0){jQuery.getJSON("/Jwxb/CN/lexeme/existsCnctstInArticle.do?articleID="+$("#articleId").val(), null, function(json){if(json.result){$("#showArticle_knowledgeMap").show();}});}});$(document).ready(function(){var metaDataStr = $.trim($("#article_metaJson").val());if(metaDataStr!=''){eval("window.metaData="+metaDataStr);}if(window.metaData && (!window.metaData.authorNotesCommon_cn && !window.metaData.authorNotesCorresp_cn && window.metaData.authorNotes_cn)){window.metaData.authorNotesCommon_cn = window.metaData.authorNotes_cn;}if(window.metaData && (!window.metaData.authorNotesCommon_en && !window.metaData.authorNotesCorresp_en && window.metaData.authorNotes_en)){window.metaData.authorNotesCommon_en = window.metaData.authorNotes_en;}var _nlmdtdXml = $("#article_nlmdtdXml").val();var magDir = _nlmdtdXml.replace(/\/[^\/]+$/,'');window.metaData.magDir = magDir;new mag_vue({ el: '#metaVue', //dataUrl: mag_currentQikanUrl() + '/EN/article/getRichHtmlJson.do?articleId='+$("#articleId").val(), data:window.metaData, loading:true, doTextFun:function(text){ return doDataJsonText(text);
