血芝属是灵芝科真菌的重要类群，研究发现该属真菌具有多种生理功能，并且部分活性优于多种已被熟知的食药用菌。本研究以5种野生血芝Sanguinoderma spp.为研究对象进行驯化栽培，以期了解其栽培特性和抗氧化活性、探究其开发利用价值。结果显示，5种血芝菌株菌丝最适生长温度不同，在25-30 ℃之间，子实体从原基发生到采收需要25-38 d不等，乌血芝生长快，孢子粉弹射早，血芝生长最慢，栽培期内未见孢子粉弹射。不同菌株的栽培子实体性状差异显著，菌盖长4.96-12.56 cm，宽3.84-10.76 cm，菌盖颜色灰褐色、灰黑色、黑色和米红色；菌柄长0-10.1 cm不等，菌盖扇形、肾形至近圆形。各菌株一茬生物转化率为6.59%-18.34%，子实体粗多糖含量为1.89%-2.95%，总三萜为0.78%-1.68%。与赤灵芝、紫灵芝、白肉灵芝相比，血芝属菌株抗氧化效果更好，其中血芝、小孔血芝粗多糖溶液、总三萜溶液浓度分别在3 mg/mL、1 mg/mL时DPPH自由基清除率达80%以上，总抗氧化自由基清除率达28%以上。血芝属真菌生长快，子实体多糖、三萜含量较高，具有较好的抗氧化应用潜力。"/>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);
