• Characterization of reduced iso-α-acids derived from hops (<i>Humulus lupulus</i>) by NMR
  作者：Lars I. Nord、Steen Bech Sørensen、Jens Ø. Duus

  DOI：10.1002/mrc.1234

  日期：2003.9

  Reduced forms of iso-α-acids (isohumulones), used in modern beer brewing were separated and characterized by 1H and 13C NMR spectroscopy. Components from mixtures of rho-iso-α-acids, tetrahydro-iso-α-acids, and hexahydro-iso-α-acids were isolated using high-performance liquid chromatography (HPLC) and analyzed by use of one- and two-dimensional NMR experiments. The data presented assign the identities of the main peaks in the HPLC traces for the reduced iso-α-acids. Previous tentative assignments regarding the cis and trans configurations and the structures of the acyl residues of the reduced iso-α-acids were confirmed and extensive NMR assignments were made. Furthermore, the previously unknown stereochemistry in the C-4 side-chain of the rho- and hexahydro-iso-α-acids was assigned. Copyright © 2003 John Wiley & Sons, Ltd.

  通过1H和13C NMR光谱分离并鉴定了现代啤酒酿造中使用的异α-酸（异胡莫酮）的还原形式。使用高效液相色谱法（HPLC）分离了来自异α-酸、四氢异α-酸和六氢异α-酸混合物的成分，并通过一维和二维NMR实验进行了分析。所呈现的数据确定了HPLC曲线中还原异α-酸主要峰的特征。先前关于还原异α-酸的顺式和反式构象以及酰基残基结构的初步测定得到了证实，并进行了大量NMR测定。此外，还确定了先前未知的异α-酸和六氢异α-酸C-4侧链的立体化学。版权所有 © 2003 John Wiley & Sons, Ltd.
