Essential oil composition of Cachrys cristata - A rare and endangered species in the Flora of Serbia

Abstract

Cachrys cristata DC. (Apiaceace) is a rare and critically endangered species in the flora of Serbia. Essential oil isolated by hydrodistillation from the aerial parts and fruits of this species was analyzed using combined GC and GC/MS. The oil from the aerial parts was rich in sesquiterpenes (45.7%) and oxygenated sesquiterpenes (32.9%), while the fruit oil consisted of a higher percentage of sesquiterpenes (48.3%) and oxygenated sesquiterpenes (36.7%). The dominant constituents in the oil from aerial parts were phytol (13.1%) and germacrene D (12.9%), while in the fruit oil suberosin (19.7%) and germacrene D (12.3%) were the most abundant.
