云南烤烟主要栽培品种化学成分比较分析

本文对红花大金元、K326、云烟85和云烟87等云南烤烟主要栽培品种的化学组成进行了比较分析.结果表明,4个主要栽培品种间在多酚总量、草酸、十四酸、亚油酸、新绿原酸、绿原酸、隐绿原酸、莰菲醇-3-0-芸香糖苷、3-羟基-2-丁酮、4-甲基-5H-呋喃-2-酮、β-大马酮、巨豆三烯酮(4种异构体)、3-甲基-2-丁烯-1-醇、寸拜醇、新植二烯等化合物的含量上存在显著差异.其中红花大金元在多酚总量、草酸、十四酸、亚油酸、新绿原酸、绿原酸、隐绿原酸、莰菲醇-3-0-芸香糖苷、寸拜醇等化合物的含量上明显高于其它品种.K326在莰菲醇-3-0-芸香糖苷、寸拜醇等化合物的含量上明显低于其它品种.云烟85、云烟87和K326在3-羟基-2-丁酮、4-甲基-5H-呋喃-2-酮、β-大马酮、巨豆三烯酮(4种异构体)、新植二烯等化合物的含量明显高于红花大金元.

Analysis of Chemical Component of Yunnan Main Cultivar Flue-cured Tobacco

Analysis of chemical component of Yunnan main cultivar flue-cured tobacco was carried out among Hongda, K326, Yunyan85 and Yunyan87. The result showed that there were remarkable difference in the content of total polyphenols, oxalic acid, tetradecanoic acid, linoleic acid, neochlorogenic acid, chlorogenic acid, cryptochlorogenic acid, kaempferol-3-o-rutinoside, 3-hydroxy-2-butanone, furan-2(5H)-one,4-methyl, β-damascone, megastigmatrienone a, megastigmatrienone b, megastigmatrienone c, megastigmatrienone d, 3-methyl-2-buten-1-ol, thunbergol and neophytadiene among the four cultivars.
