采用酶解方法分离K326、红花大金元、云烟87、云烟202、K346中部适熟叶栅栏组织和海绵组织，然后用气相色谱分析鉴定非挥发性有机酸，用分光光度计法分析质体色素、糖类及烟碱。结果表明多元有机酸、烟碱在海绵组织中含量较高，高级脂肪酸、质体色素、糖在栅栏组织中含量较高。栅栏组织化学成分差异：总非挥发性有机酸含量排序是红大〉K326〉K346〉云87〉云202；总叶绿素和总类胡萝卜素都是红大最高；总糖是红大〉K346〉云87〉云202〉K326；烟碱是K326〉云87〉K346〉红大〉云202。海绵组织化学成分：总非挥发性有机酸是红大〉K326〉K346〉云87〉云202；总叶绿素和总类胡萝卜素也是红大最高；总糖...

Palisade mesophyll and spongy mesophyll of ripped middle leaves of five flue-cured tobacco varieties, K326, K346, Yun87, Yun202, HongDa, were separated by pectinase. Nonvolatile organic acid was detected by gas chromatography. Plastid pigment, glucide, and nicotine were analyzed by spectrophotometer. Results showed that the content of multiple organic acid and nicotine in spongy mesophyll was higher than that in palisade nents. In palisade 〉 Yun202; that of 〉 Yun202 〉 K346, Yun87 〉 Yun202; Yun202 〉 Yun87 〉 mesophyll, while it was on the c...
