OXYGENATED DERIVATIVES OF MENTHATRIENE IN PARSLEY LEAVES

Article abstract of DOI:10.1016/0031-9422(89)80278-X

The analysis of aroma volatiles of parsley revealed the presence of two novel oxygenated p-mentha-1,3,8-tiene 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)-3,8-dioxatricyclo<5.1.0^2-4>octane.Key Word Index - Petroselinum crispum; Umbelliferae; parsley; aroma volatiles; p-mentha-1,3,8-triene; dioxetane; 1-methyl-4-(methylethenyl)-2,3-dioxabicyclo<2.2.2>oct-5-ene; diepoxide; 4-methyl-7-(methylethenyl)-3,8-dioxatricyclo<5.1.0^2-4>octane.
