摘要
本文建立了自动固相萃取一反相高效液相色谱（ASPE—RP—HPLC）法检测造纸法再造烟叶浓缩液中单宁酸的方法。结果表明单宁酸的浓度在2～117μg／mL的范围内有良好的线性关系，单宁酸的加标回收率大于87．3％，检出限为0．2μg／mL。该方法操作简单，快速准确，可用于烟叶、烟梗中单宁酸含量分析，检测造纸法再造烟叶浓缩液的单宁酸尤其有效。
The content of tannic acid extracted from tobacco leaf and tobacco peduncle is analyzed by automated solid phase extraction（ASPE） and reversed-phase high performance liquid chromatography （RP- HPLC）. The results show that there is a good linear relation about the concentration of tannic acid in the range of 2--117ug/mL, and the recovery of tannic acid is more than 87.3%, the detection limit is 0.2μg/mL. The method is simple, rapid and accurate.
