摘　　要：为了解烟用天然香料中有机酸和无机阴离子的分布特征,采用超声辅助萃取-离子色谱方法定量考察了202种烟用天然香料中的乙酸、乳酸、苹果酸、富马酸、柠檬酸、Cl^(-)、NO_(2)^(-)、SO_(4)^(2-)和PO_(4)^(3-),并采用单因素方差分析和主成分分析法分析相关数据。结果表明:①不同种类天然香料中有机酸和无机阴离子的浓度差异较大。浓缩物、提取物和浸膏中有机酸和无机阴离子的浓度均值高于精油和净油,酊剂和树脂中有机酸和无机阴离子的浓度均值居中;枣类天然香料中富马酸和梅子类天然香料中柠檬酸的浓度均值显著高于其他类天然香料。②不同产品类型和原料种类的天然香料中有机酸和无机阴离子分布特征明显,这对于天然香料的品质评价和调香时天然香料的选用具有重要参考价值。In order to investigate the distribution characteristics of organic acids and inorganic anions in natural tobacco flavors,an ultrasound-assisted extraction-ion chromatography method was used to quantify the acetic acid,lactic acid,malic acid,fumaric acid,citric acid,Cl^(-),NO^(2-),SO_(4)^(2-)and PO_(4)^(3-)in 202 natural tobacco flavor samples,the concentration data of those organic acids and inorganic anions were analyzed by one-way analysis of variance and principal component analysis methods.The results showed that:1)The concentrations of organic acids and inorganic anions in different natural flavor samples differed significantly.The mean concentrations of organic acids and inorganic anions in concentrate,extraction and extract samples were higher than those in essential oil and absolute oil samples,and those in tincture and resin samples were moderate.The mean concentration of fumaric acid in natural flavor samples from jujube and that of citric acid in natural flavor samples from Prunus mume were higher than the other samples.2)The distribution characteristics of organic acids and inorganic anions in natural flavor samples correlated to raw materials and product types,which could assist the quality evaluation of natural flavors and the selection of natural flavors in cigarette flavoring.
