Abstract

The composition of the essential oil of Nepeta nuda L. ssp. albiflora (Boiss.) Gams (Lamiaceae) was analysed by means of capillary GC and GC-MS. The main components, accounting for 75.1% of the oil, were 4aα,7α,7aα-nepetalactone (37.5%) and 4aα,7α,7aβ-nepetalactone (37.6%). The sesquiterpene fraction amounted to 14.2% and was dominated by caryophyllene oxide (4.4%).
