This paper reports on the volatile components of oils from the aerial parts (CBA) and roots (CBR) of Centaurea bracteata Scop. and aerial parts of C. pannonica (Heuffel) Simonkai subsp. pannonica (CPA), two Asteraceae growing wild in Croatia. The volatile components, obtained by hydrodistillation, were determined by GC-MS analysis. The yields (w/w) of the dried oils were 0.10% (CBA), 0.22% (CBR) and 0.09% (CPA), respectively. A total of 91 compounds were identified accounting for 91.1%, 93.3% and 87.9% of the total oil for CBA, CBR and CPA, respectively. All the samples were characterized mainly by hydrocarbons (7.1-34.1%), fatty acids (9.7-45.9%), and oxygenated sesquiterpenes (15.2-16.6%). The major components of the samples were hexadecanoic acid (8.1-31.1%), nonacosane (0.6-13.4%) and caryophyllene oxide (4.5-11.9%). Monoterpenes, both hydrocarbons and oxygenated, were either absent or present in low amounts in all the oils. The similarity in the oil contents is consistent with the two species being placed in the same section, Jacea.

The essential oils of Centaurea gracilenta Velen. (CG) and C. ovina Pall. ex Willd. ssp. besserana (DC.) Dostál (COB) growing wild in Bulgaria, were studied by GC and GC-MS. Forty-five compounds for CG, representing the 90.1% of the oil, and 68 compounds for COB, representing the 91.9% of the oil, were identified. The oils were rich in sesquiterpenoids (33.4% for CG and 27.3% for COB), hydrocarbons (28.3% for CG and 10.7% for COB) and carbonylic compounds (12.7% for CG and 13.1% for COB). Fatty acids were abundant only for COB (31.3%). β-Eudesmol (12.8%), nonacosane (11.8%) and p-vinyl guiacol (7.5%) were recognized as the main constituents for CG, while hexadecanoic acid (21.4%), spathulenol (7.9%), β-eudesmol (5.8%) and caryophyllene oxide (5.7%) were the main compounds for COB.

Sideritis caesarea H. Duman, Aytaç & Başer of the Lamiaceae is an Anatolian endemic species, and is mainly used as herbal tea and folk medicine. This present study aimed to determine and compare the chemical compositions of the volatile components of S. caesarea specimens collected from different localities in Kayseri province, Turkey: Sariz town (samples A and B), Pınarbaşı-Kaynar (sample C) and Pınarbaşı-Şirvan Mountain (sample D), respectively. Initially, the essential oils of the aerial parts were obtained by hydrodistillation and analysed both by gas chromatography-flame ionization detector (GC-FID), gas chromatography/mass spectrometer (GC/MS), simultaneously. Major volatile components of samples A and D were characterized as hexadecanoic acid (19.7 and 20.5%), caryophyllene oxide (6.7 and 20.2%), β-caryophyllene (6.5 and 12.6%), respectively. In sample B, hexadecanoic acid (14.6%), β-caryophyllene (11.5%) and caryophyllene oxide (8.3%) were detected as the major components. Whereas caryophyllene oxide (13.7%), hexadecanoic acid (8.5%) and spathulenol (6.1%) were the main components of the essential oil of sample C. Besides the chemical profiling, in vitro antimicrobial effects of samples were evaluated against a panel of six pathogenic microorganisms. Inhibition zones of the tested samples varied against bacteria with low to moderate activity, where no susceptibility against Candida albicans was observed.
