subfraction of Oriental tobacco condensate led to the identification of 47 compounds. Of these 21 have hitherto not been reported as Oriental tobacco constituents, and 14 appear to be novel to all tobacco types. The latter are (E)-3-methyl-non-2-en-4-one (1), (E)-1-(2, 3, 6-trimethylphenyl)-but-2-en-1-one (3), pentadecan-15-olide (12), 8α, 13:9α, 13-diepoxy-15, 16-dinorlabdane (17), (Z)-octadec-9-en-18-olide
通过气相色谱法对东方烟草冷凝液的一个小但感官上典型的亚组分进行了调查,结果鉴定出47种化合物。迄今为止,在这21种烟草中,尚无东方香料成分的报道,其中14种似乎对所有烟草类型都是新颖的。后者是(E)-3-甲基-非-2-en-4-one(1),(E)-1-(2,3,6-三甲基苯基)-but-2-en-1-one(3),十五碳五烯酸15(12),8α,13:9α,13-二环氧15,16-二氯丹烷(17),(Z)-十八碳九-en-18-氮氧化物(18),(E)-2-亚乙基-6,10,14-三甲基十五烷(21)时,norlabdanoids 9,10,11,14,15,16,十三烷-2-酮,和2-苯乙基异戊酸酯。大环内酯12和18代表在烟草中检测到的首批麝香化合物。通过直接比较(MS和/或1 H-NMR./IR。)与必要时合成的真实化学物质进行鉴定。
