CHEMODIVERSITY OF HELICHRYSUM ITALICUM (ROTH) G. DON SUBSP. ITALICUM ESSENTIAL OILS FROM BOSNIA AND HERZEGOVINA

摘要

The chemical composition of essential oil samples isolated from immortelle (Helichrysum italicum (Roth.) G.Don.subsp.italicum) collected on ten locations in Bosnia and Herzegovina was determined by GC/MS analysis.The whole wild population growing on different altitudes and soil types is covered in flowering period,with the aim of determining chemotype of EOs.Each of the examined EOs was characterized by a high content of sesquiterpene hydrocarbons (mean value 32.5 ),followed by oxigenated monoterpenes (20.9 ),monoterpene hydrocarbons (16.3 ),diketones (17.9 ),non-ter-pene esters (5.5 ) and oxigenated sesquiterpenes (5.0 ).The main compounds were y-curcumene (12.6 ),neryl acetate (11.5 ),a-pinene (10.7 ) and 4,6,9-trimethyldec-8-en-3,5-dione (7.9).To compare the chemical variability of the immortelle EOs from Bamp;H with the other Mediterranean areas,studied previously,multivariate statistical analysis was performed (PCA and CA).The essential oils from Bamp;H in chemical composition are similar to those from the Adriatic region (Croatia and southeast Italy),and different from Tyrrhenian islands’ oils.These EOs were distinguished by the content of y-and yS-curcumene,a-bergamotene and italicene.The essential oils isolated from Bamp;H immortelle possess specific chemical composition which gives them high quality and geographic distinctiveness.
