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
