摘　　要：[目的]研究产地、等级、部位、醇化时间对烟叶木质素含量的影响。[方法]以河南地区98个烟叶样品为研究对象,采用氢氧化钠/尿素-稀硫酸法测定其木质素含量,研究产地、等级、部位和醇化时间对烟叶木质素含量的影响。[结果]随着烟叶等级的升高(烟叶部位由上到下),总木质素含量呈增加趋势;随着醇化时间的延长,总木质素含量呈缓慢增加趋势;产地、等级、部位对烟叶木质素含量影响较大,而醇化时间对烟叶木质素含量影响较小。[结论]该研究可为合理利用烟叶、改善烟草品质提供理论依据。[ Objective ] To investigate effects of producing area, grade, position, alcoholization duration time on the lignin content in tobacco leaves. [ Method]The lignin content of 98 tobacco samples from Henan area were determined by sodium hydroxide/urea-dilute sulfuric acid method and the difference of their effects on lignin content were studied by variance analysis. [Result] With the increase of tobacco leaf rank（ from top to bottom） ,the contents of total lignin increased; With the extension of alcoholization duration time, the lignin content showed a slow increasing trend;Producing area, grade, position had significant influence on the lignin content in tobacco leaves while alcoholization duration had a little influence. [ Conclusionl The study can provide theoretical basis for the rational use of tobacco leaf and improving tobacco qualitv.
