    来自鳄鱼粘杆菌和海洋细菌的新型吡嗪
    摘要:
    使用 CLSA 或 SPME 顶空方法收集了来自北海的 2 株粘杆菌 Chondromyces crocatus 和 7 株海洋 Alphaproteobacteria 释放的挥发物,并通过 GC-MS 进行分析。在 C. crocatus 的提取物中鉴定出属于不同类别的 27 种吡嗪。2,5-二烷基吡嗪和相关的3-甲氧基-2,5-二烷基吡嗪占主导地位。从天然来源获得了几种吡嗪,如 2-(1-甲基乙烯基)-5-(1-甲基乙基)吡嗪 (7) 和具有甲基、异丙基、异丁基或仲丁基侧链的 3-甲氧基-2,5-二烷基吡嗪首次。鉴定必须依赖合成参考材料,这些参考材料是使用 Furstner 铁催化的氯吡嗪与格氏试剂偶联或叠氮酮缩合获得的关键步骤。合成材料允许鉴定两种以前未知的细菌来源的菠萝甲虫 Carpophilus humeralis 引诱剂,即 3-甲氧基-2-(1-甲基丙基)-5-(2-甲基丙基)吡嗪

  • Isolation and Identification of 2-Methoxy-3,5-dimethylpyrazine, a Potent Musty Compound from Wine Corks
    作者:Robert F. Simpson、Dimitra L. Capone、Mark A. Sefton
    DOI:10.1021/jf049484z
    日期:2004.8.1
    5-dimethylpyrazine is an extremely potent compound with an unpleasant, musty, moldy aroma and an aroma threshold in a white wine of 2.1 ng/L. While its contribution to the frequency and intensity of cork taint in bottled wine is yet to be established, it has been assessed by some wine industry personnel as second only to 2,4,6-trichloroanisole as a cause of cork taint in Australian wine.
    在葡萄酒瓶塞的行业评估中,明显地带有“真菌必不可少”的污染的化合物被鉴定为2-甲氧基-3,5-二甲基吡嗪。在气相色谱/气味分析的基础上进行鉴定,使用微量制备技术收集材料,确定所收集材料的化学性质,并通过气相色谱/质谱法与由2-羟基-3合成的真实样品进行比较, 5-二甲基吡嗪2-甲氧基-3,5-二甲基吡嗪是一种非常有效的化合物,具有令人不快,发霉,发霉的香气,在白葡萄酒中的香气阈值为2.1 ng / L。尽管它对瓶装葡萄酒中软木塞味的频率和强度的贡献尚待确定,但一些葡萄酒行业人员将其评估为仅次于2,4,

  • METHOD FOR DETECTING A VOLATILE ANALYTE FOR CLASSING AND SORTING CORK STOPPERS DEPENDING ON THE CONCENTRATION OF THE ANALYTE
    申请人:Cork Supply Portugal, S.A.
    公开号:EP3165918A1
    公开(公告)日:2017-05-10
    A method for detecting a volatile analyte for categorization and separation of cork stoppers depending on the concentration of the said analyte, with the detection being carried out in concentrations within the range of ng/L (parts per trillion), in a concentrated gas over the cork stoppers, confined to a closed conditioning system. In the said method, the cork stoppers are separately or jointly led to an incubation chamber (1); air or nitrogen is injected into the incubation chamber (1), dragging the gas enriched in the cork's volatile compounds and carrying it to the concentration system which is provided with a trap (4), the latter being meanwhile heated for desorption of the volatile compounds; these are led by the dragging gas towards a detection system (6) which registers a signal related to the presence of the analyte, this signal being used for purposes of classification of the cork stopper or groups of cork stoppers; finally, a software receives the signal and compares it with the established minimum threshold, taking a decision of approval or rejection. An installation for the operation of the said method is also described.
