摘要
为了解雪茄烟叶烟霜的化学组成,采用原子吸收光谱法、离子色谱法、紫外可见分光光度法和气相色谱/质谱法测定了烟霜中的离子和挥发性有机化学成分。结果表明:烟霜中检出Ca2+,Mg2+,K+,Na+,NH4+,PO43-,C l-,NO3-,NO2-和SO42-等无机离子,其相对含量各为4.5%,0.9%,22.5%,2%,9.4%,0.4%,9.9%,33.2%,1.5%,3.8%,共约占烟霜重量的88%;烟霜中的挥发性成分以赤藓糖醇、l-苏糖醇、木糖醇和dl-苏丁醇等为主,另外还有少量的烷烃类。雪茄烟叶烟霜是一种由硝酸钾、氯化铵和少量的挥发性有机物组成的混合物。
To investigate the chemical composition of the bloom on cigar leaf,inorganic ions and volatile organic compounds in the bloom were extracted with water and simultaneous distillation and extraction,and determined by atomic absorption spectrometry,ionic chromatography,UV spectrophotometry and gas chromatography/mass spectroscopy,respectively.The results showed that inorganic ions,including Ca2＋,Mg2＋,K＋,Na＋,NH＋4,PO3-4,Cl-,NO-3,NO-2 and SO2-4 were detected,which accounted for 4.5%,0.9%,22.5%,2%,9.4%,0.4%,9.9%,33.2%,1.5%,3.8% of bloom weight,respectively;while totally accounted for 88%.The major volatile organic compounds were erythritol,l-threitol,xylitol and dl-threitol and a small quantity of alkanes.It was concluded that the bloom of cigar leaf was a kind of mixture composed of KNO3,NH4Cl,as major constituents,and some volatile organic compounds.
