摘　　要：对2013年采自广东省10个生态区的18个烟叶样品和采自广西省22个生态区的22个烟叶样品中角鲨烯含量进行了分析。结果表明:广东省和广西省生态区烟叶中角鲨烯平均含量分别为24.57和18.44 mg/kg;不同等级烟叶中B2F等级角鲨烯含量高于C3F和X2F;所取样品中以广东省马市镇砂泥田种植的K326品种的B2F等级烟叶的角鲨烯含量最高,为39.63 mg/kg;含有砂质,质地疏松,pH值中性偏弱酸性的植烟土壤有利于烟叶中角鲨烯的积累,同时土壤中微量元素Zn含量丰富也有利于角鲨烯的积累。This study was conducted to determine squalene in flue-cured tobacco leaf in major tobacco production areas in Southern China,the substance in flue cured tobacco leaf was extracted by Soxhlet extractor with petroleum ether,and then squalene was separated and determined by gas chromatography/mass spectrometry(GC/MS)with selected ion monitoring.The average content of squalene in fluecured tobacco in the production areas of Guangdong was24.57mg/kg,and that of Guangxi was18.44mg/kg.The content of squalene in the B2F grade of flue-cured tobacco leaf generally was higher than that of the C3F or X2F grade.The highest content of squalene in fluecured tobacco leaf was39.63mg/kg in the B2F-graded leaf of the variety K326cultivated in Mashi town of Guangdong with sand mud field soil.The neutral to slightly acidic porous sandy soil was conducive to accumulation of squalene in flue-cured tobacco leaf,and so was the Zn element in soil.
