摘　　要：对高效液相色谱法分离酒花中α-酸和β-酸的色谱条件进行了优化,并对合葎草酮和葎草酮+加葎草酮,以及合蛇麻酮和蛇麻酮+加蛇麻酮进行了定量,确定了色谱条件,并对该方法的精密度和准确度进行了验证。同时应用该方法,对颗粒酒花储藏期间α-酸和β-酸各组分的变化进行了分析,并结合酒花储藏指数(HSI)的变化,从而对储藏期间酒花在生产中的应用提供了指导。HPLC conditions for the separation of α -acid and α-acid in hops were optimized. Besides, cohumulone and humulone＋adhumulone, and colupulone and lupulone＋ adlupulone were quantified to determine HPLC conditions. The precision and the accuracy of HPLC were verified. Meanwhile, HPLC was used to analyze the change of α-acid and β-acid content during the storage of hops. Combined with the change of HSI, the data could be used to guide hops （in storage period） utilization in beer production. （Tran. by YUE Yang）
