不同方法制备雷竹竹沥化学成分分析 　　摘要：分别采用烧制法、干馏法和渗漉法3种不同方法提取雷竹（Phyllostachys praecox）竹沥，运用气相色谱-质谱联用技术（GC-MS）分析所含化学成分的差异。结果表明，烧制法提取竹沥检出峰104个，可定性成分为20个，含量占总检出成分的62.89%；干馏法提取竹沥检出峰100个，可定性成分21个，含量占总检出成分的57.14%；渗漉法提取竹沥检出峰99个，可定性成分33个，含量占总检出成分的64.81%。雷竹竹沥所含的有机化合物含量与不同的提取方法有关，有机酸类化合物提取应采用烧制法；醛类化合物、醇类化合物提取宜采用渗漉法；酚类化合物提取采用干馏法最优 关键词：雷竹（Phyllostachys praecox）；竹沥；烧制法；干馏法；渗漉法；GC-MS 中图分类号：S795.7；R284.2 文献标识码：A 文章编号：0439-8114（2017）09-1730-04 DOI：10.14088/j.cnki.issn0439-8114.2017.09.032 Analysis of Chemical Composition of Phyllostachys praecox Succus Bambusae with Different Preparing Methods ZHANG Gui-fu，CHEN Ya （School of Nuclear Technology and Chemistry Biology， Hubei University of Science and Technology， Xianning 437100，Hubei，China） Abstract： To study the difference of the chemical composition of Phyllostachys praecox bamboo juice between three different preparation methods. extracting succus bambusae with the method of calcinations，dry distillation and percolation，the test was carried out through GC-MS. The results showed that 104 peaks of the Phyllostachys praecox liquid of extracting with calcinations were detected，and 20 compounds were identified，accounted for the total detection component of 62.89%；the extraction succus bambusae in dry distillation containing 100 peaks were detected，21 compounds were qualitative data，57.14% of the total detection component；percolation method for extracting bamboo juice and 99 peaks were checkout，33 compounds were qualitatived，the total detection component of 64.81%. The content of organic compounds of Phyllostachys praecox succus bambusae were concerned with different extraction methods. Organic acid compounds were extracted by calcinations method；extractting compounds of aldehyde and alcohol by percolation method；phenolic compounds the dry distillation method wae used to extract phenolic compounds.
