revealed the presence of two novel oxygenated p -mentha-1,3,8triene derivatives, the amounts of which increase during processing of plant material and deteriorate the typical fresh aroma. The two derivatives, which could be synthesized by means of a dye sensitized photooxygenation reaction, were identified as 1-methyl-4-(methylethenyl)-2,3-dioxabicyclo[2.2.2]oct-5-ene and 4-methyl-7-(methylethenyl)-3
摘要 欧芹香气挥发物的分析表明,存在两种新型含氧对薄荷脑-1,3,8 三烯衍生物,其数量在植物材料加工过程中增加,破坏了典型的新鲜香气。这两种衍生物可以通过染料敏化光氧化反应合成,被鉴定为 1-甲基-4-(甲基乙烯基)-2,3-二氧杂双环[2.2.2]辛-5-烯和4-甲基- 7-(甲基乙烯基)-3,8二氧杂三环[5.1.0 2–4 ]辛烷。
