在塞浦路斯和其他国家生产的42种酒精饮料中，通过HPLC和GC色谱法，（1）H NMR和ICP光谱法以及其他技术测定了26种化学和物理化学变量。数据处理采用多元化学计量学技术，包括主成分分析，聚类分析，正则化判别分析，分类和回归树。Zivania可以与其他国家的饮料区分开来。以2-和3-甲基丁醇、2-甲基丙醇、糠醛、甲醇、醇级和~（1）H NMR谱中-CH（3）的化学位移为特征，对Zivania进行了近正确的分类。给出了分流的原因。
In 42 alcoholic beverages produced in Cyprus and other countries, 26 chemical and physical-chemical variables were determined by HPLC and GC chromatography, (1)H NMR and ICP spectroscopy, and other techniques. Data were processed using multivariate chemometric techniques, involving principal component analysis, cluster analysis, regularized discriminant analysis, and classification and regression trees. Zivania can be differentiated from beverages from other countries. Using 2- and 3-methyl-butanol, 2-methyl-propanol, furfural, methanol, and the alcoholic grade and the chemical shift of -CH(3) in (1)H NMR spectra as features, a nearly correct classification for zivania was achieved. The reasons for diversions are given.
