摘　　要：龙爪果提取物在烟草中的加香应用罕有文献报道,因此比较了不同体积分数乙醇提取的龙爪果提取物在卷烟中的加香效果,结果表明,70%醇(体积分数)提取物的加香效果最理想。为了解其在卷烟燃吸时对烟气的贡献,将龙爪果70%醇提物在模拟燃吸条件下进行热裂解,并通过气相色谱–质谱联用仪分析其裂解产物。结果表明,龙爪果70%醇提物的裂解产物主要包括:有机酸类化合物26.68%、呋喃类化合物15.79%、吡喃类化合物7.75%、醇类化合物12.33%、酮类化合物9.56%、吡咯类化合物4.78%。这些化合物可降低烟气刺激性,使烟气柔和细腻,丰富和增浓烟气,提升香气质和香气量,对卷烟产品的品质提升有明显作用。因此,龙爪果70%醇提物可用于烟草产品的开发中。The flavoring effect of extracts of Hovenia dulcis fruit extracted with different concentration of ethanol on cigarettes was compared.The results show that 70%(volume fraction)ethanol extracts have the best flavoring effect.In order to understand its contribution to smoke during cigarette burning,the 70%ethanol extract of Hovenia dulcis fruit was pyrolyzed under simulated cigarette burning conditions.The pyrolysis products were analyzed by the pyrolysis gas chromatography-mass spectrometry(GC-MS)instrument.The results show that the pyrolysis products of 70%ethanol extract of Hovenia dulcis fruit mainly include organic acids 26.68%,furans 15.79%,pyranes 7.75%,alcohols12.33%,ketones 9.56%and pyroles 4.78%.These compounds can reduce the irritation of smoke,make the smoke soft and delicate,enrich the smoke,enhance the aroma quality and quantity,and have obvious effect on improving the quality of cigarette products.Therefore,the 70%ethanol extract of Hovenia dulcis fruit can be used in the development of tobacco products.
