Constituents of the essential oil of lippia integrifolia (Griseb.) Hieron. (Verbenaceae)

The essential oil of Lippia integrifolia was analysed by capillary GC interfaced with MS. The main constituents were isolated by using column chromatography and reversed-phase liquid chromatography and their structures established by spectroscopic methods. The major constituent of the oil is lippifo...

Essential oil Sesquiterpenes Stereochemistry Structure Verbenaceae The essential oil of Lippia integrifolia was analysed by capillary GC interfaced with MS. The main constituents were isolated by using column chromatography and reversed-phase liquid chromatography and their structures established by spectroscopic methods. The major constituent of the oil is lippifoli-l(6)-en-5-one (4), a ketone based on a new sesquiterpene skeleton named lippifoliane. Ketone 4 biogenetically derives from integrifolian-1,5-dione (2), which is also a constituent of the oil. In addition to several known mono and sesquiterpenes the following new sesquiterpenes were identified: trans-humul-9(E)-en-2,6-dione (8); 4,5-seco-african-4,5-dione (9); 1,6-cis-and 1,6-trans-lippifolian-1α-o1-5-one (5) and (6) respectively; lippifoli-1(6)-en-4α-o1-5-one (7) and the sesquiterpenes 10 - 12 whose structures and conformations are discussed.
