The chemical composition and antioxidant properties of the essential oil and EtOH extract of immortelle (Helichrysum italicum (Roth) G.Don subsp. italicum, Asteraceae) collected in Montenegro were evaluated. The essential oil was characterized by GC/MS analysis, and the content of total phenolics and flavonoids in the EtOH extract was determined using the FolinCiocalteu reagent. The free-radical-scavenging capacity (RSC) of both the essential oil and the EtOH extract was assessed with the 2,2-diphenyl-1-pycrylhydrazyl (DPPH) method. Moreover, the inhibition of hydroxyl radical ((.) OH) generation by the EtOH extract of immortelle was evaluated for the first time here. Neryl acetate (28.2%) and γ-curcumene (18.8%) were the main compounds in the essential oil, followed by neryl propionate (9.1%) and ar-curcumene (8.3%). The chemical composition of the oils of the examined and additional 16 selected Helichrysum italicum taxa described in literature were compared using principal component (PCA) and cluster (CA) analyses.

OBJECTIVE: This study is designed to extract and examine chemical composition, antimicrobial and antioxidant activity of the hydro-distillated essential oil of Murraya koenigii leaves from the south region of Tamilnadu, India. Matherials and Methods: Gas Chromatography (GC) and Gas Chromatography-Mass Spectrometry (GC-MS) analysis of the essential oil result was indicates the 33 different compounds representing 97.56 % of the total oil.

The chemical composition of the essential oils isolated from the aerial parts of Anthemis pignattiorum Guarino, Raimondo & Domina and A. ismelia Lojac. and the aerial parts and flowers of Anthemis cupaniana Tod. ex Nyman, three endemic Sicilian species belonging to the section Hiorthia, was determined by GC-FID and GC/MS analyses. (Z)-Muurola-4(14),5-diene (27.3%) was recognized as the main constituent of the A. pignattiorum essential oil, together with isospathulenol (10.6%), sabinene (7.7%), and artemisyl acetate (6.8%), while in the oil obtained from the aerial parts of A. ismelia, geranyl propionate (8.8%), bornyl acetate (7.9%), β-thujone (7.8%), neryl propionate (6.5%), and τ-muurolol (6.5%) prevailed. α-Pinene was the main compound of both the aerial part and flower oils of A. cupaniana (18.4 and 13.2%, resp.). Also noteworthy are the considerable amounts of artemisyl acetate (12.7%) and β-thujone (11.8%) found in the oil from the aerial parts and those of tricosane (9.
