目的:分析地果研究领域的现状和发展趋势,为其研究和应用提供参考。方法:以中国知网(CNKI)期刊全文数据库和Web of Science核心数据库为文献来源,基于CiteSpace对地果研究领域的发文量、发文机构、研究作者、关键词和高被引文献进行分...目的:分析地果研究领域的现状和发展趋势,为其研究和应用提供参考。方法:以中国知网(CNKI)期刊全文数据库和Web of Science核心数据库为文献来源,基于CiteSpace对地果研究领域的发文量、发文机构、研究作者、关键词和高被引文献进行分析。结果:地果研究相关文献的数量处于波动状态,总量较少,质量还需提升;中国是研究地果的主要国家,且国内研究机构主要位于其自然分布区域内,国际上对地果的关注极少。国内核心作者源于机构内的合作,机构之间协作较少。总黄酮和化学成分等主题是当前地果的研究热点。结论:目前,对地果的研究少、开发利用程度低,未来应加强品种选育以发挥其在园林、药用、食用和生态修复等方面的优良特性,同时应加强对其系统发育和地果-榕小蜂协同进化等研究。展开更多
建立野地瓜果实中香气成分的SPME-GC-MS检测方法。同时,优化固相微萃取的条件:萃取温度50℃,萃取时间40 min,萃取时加入8 g Na Cl电解质。冰冻后野地瓜果实中共检测出152种挥发性物质,占总检出物质的99.03%。主要为酯类,占33.06%;醇类,...建立野地瓜果实中香气成分的SPME-GC-MS检测方法。同时,优化固相微萃取的条件:萃取温度50℃,萃取时间40 min,萃取时加入8 g Na Cl电解质。冰冻后野地瓜果实中共检测出152种挥发性物质,占总检出物质的99.03%。主要为酯类,占33.06%;醇类,占13.14%;烷烃类,占13.38%;还有酮类,醛类,酸类等物质。含量较高的10种香气成分依次为愈创木酚(14.71%),环丁烷羧酸十二烷基酯(13.54%),正十三烷(6.05%),2-十三烷酮(4.72%),环己硅氧烷(4.44%),环丁烷羧酸癸酯(4.18%),甲基壬基甲酮(3.62%),乙酸(2.98%),环戊烷羧酸十三酯(2.48%),2-十四烷醇(2.31%),等。展开更多
