对亚洲兰茂牛肝菌Lanmaoa asiatica (“见手青”)的化学成分和生物活性进行研究。采用多种柱色谱技术以及重结晶等方式对其95%乙醇提取物的乙酸乙酯萃取物进行分离纯化，共得到17个单体化合物。根据波谱数据及文献比对鉴定了化合物的结构，其中9个为甾体类化合物：citreoanthrasteroid (1)、1(10→6)abeo-麦角甾-5,7,9,22-四烯-11β-甲氧基-3α-醇(2)、3β,5α,9α-trihydroxy- 6β-methoxyergosta-7,22-dien (3)、过氧化麦角甾醇(4)、9(11)-去氢过氧化麦角甾醇(5)、3β-羟基-(22E,24R)-麦角甾-5,8(9),22-烯-7-酮(6)、(24S)-麦角甾-7-烯-3β-醇(7)、22E,24R-麦角甾-7,22-二烯-3β-醇(8)和麦角甾醇(9)；其余化合物分别为：腺嘌呤核苷(10)、5’-deoxy-5’-methylamino-adenosine (11)、5’-deoxy-5’-methylamino-9-(α-L-lyxofuranosyl)adenine (12)、(R)-4-methylpiperidin-2-one (13)、尿嘧啶核苷(14)、尿嘧啶(15)、烟酰胺(16)和1(2)-linolyl-2(1)-palmityl-glycero-O-4’-(N,N,N-trimethyl) homoserine (17)。其中化合物1-3的核磁信号全归属为首次报道，化合物13为新天然产物，化合物1-17均为该种首次分离。利用MTT法测定化合物对肿瘤细胞的细胞毒活性，结果显示甾体类化合物1、3-6和9对人乳腺癌细胞(MCF-7)、小鼠小胶质细胞(BV2)和人肺癌细胞(A549)均有较强的细胞毒活性。化合物10对BV2细胞呈现出中等强度的细胞毒活性，其IC50值为48.34 μmol/L。本研究对亚洲兰茂牛肝菌的化学成分进行了较为系统的研究，对亚洲兰茂牛肝菌的进一步开发利用具有重要意义。"/>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);
