１引言 α－酸和β－酸的常规分析方法是采用合适的有机溶剂萃取酒花及其制品，分光光度法和电导法测定α－酸和β－酸，二种方法均受α－酸和β－酸的氧化产物的影响，不适于测定衰老和质量差的酒花及其制品。目前国外较多采用高效液相色谱法（ＨＰＬＣ）分析酒花及其制品中α
1 Introduction The conventional method for the analysis of alpha acids and beta acids is the extraction of hops and their products using a suitable organic solvent. The alpha and beta acids are determined spectrophotometrically and by conductivity, both of which are affected by alpha-acids and beta - Acid oxidation products, not suitable for determination of aging and poor quality hop and its products. At present, foreign countries use high performance liquid chromatography (HPLC) analysis of hops and their products α
