Chemical composition of the essential oil hydrodistilled from aerial parts of Sonchus arvensis subsp. uliginosus is reported for the first time. GC and GC-MS analyses of the oil enabled the identification of 114 components that represented 97.4% of the total oil. Main identified constituents were heneicosane (28.4%), ( Z)-3-hexen-1-ol (19.0%), ( E)-2-hexen-1-ol (11.6%), 1-eicosanol (7.5%) and tricosane (5.3%). Fatty acid derived compounds (“green leaf” volatiles, alkanes, n-alkenes, n-aldehydes and n-alcohols) were by far predominant (89.4%). A much lower percentage of shikimate metabolites (5.0%), carotenoid-derived compounds (1.7%) and terpenoids (0.9%) has also been detected in the oil. Compositions of the essential oils of S. arvensis subsp. uliginosus and other 18 randomly chosen species, characterized by a wide range of essential oil yields, belonging to different plant genera, were compared using multivariate statistical analysis. The results strongly suggest that the main volatiles of essential oil poor species (yields less then 0.1%) are fatty acid- and carotenoid derived compounds, while essential oil rich taxa (essential oil yields much higher then 0.1%) are generally characterized by the specific production of mono- and sesquiterpenoids, and/or phenylpropanoids.

The chemical composition of the essential oil obtained from the aerial parts of Cleome serrata by hydrodistillation was analyzed by employing GC-FID, GC-MS and RI. Fourteen compounds comprising 90.4% of the total oil composition were characterized. The main components identified were ( Z)-phytol (53.0%) and di(2-ethylhexyl)-phthalate (DEHP) (14.7%). The oil was evaluated for its in vitro antimicrobial activities against nine pathogenic microorganisms using the filter paper disc diffusion method. Moderate antimicrobial activity was observed against five of the pathogens assayed. In addition, the essential oil was tested against the sweet potato weevil, Cylas formicarius elegantulus.

The essential oil from the aerial parts of Tanacetum nubigenum Wallich ex DC collected from the Milam glacier moraine showed the presence of 73 compounds, of which 69, representing 87.9% of the total oil, have been identified, with bornyl acetate (39.7%), borneol (10.6%), ( E)-β-farnesene (6.6%) and 1,8-cineole (5.8%) as major constituents, while the oil from the plant material from the Pindari glacier area contained a total of 81 compounds, of which 77 have been identified. This oil was characterized by the presence of (3 R, 6 R)-linalool oxide acetate (69.4%), β-eudesmol (3.2%), selin-11-en-4α-ol (3.2%) and (3.2% and 1.2%, respectively) for compounds ( E) and ( Z)-2-(2,4-hexadiynylidene)-1,6-dioxospiro [4,4] non-3-ene, respectively. The major constituents of the essential oils from the aerial parts were separated and characterized by GC, GC/MS and 1D- and 2D-NMR spectroscopy. The chemical differences between the two essential oils place them as distinct chemical races or chemotypes.

Variations in the essential oil composition of aerial parts of pineapple weed (Chamomilla suaveolens (Pursh) Rydb.) growing wild in Estonia, were determined using GC/FID and GC/MS. Forty-four components were identified, representing over 90% of the total oil. Nine compounds have not been mentioned in the literature before. The principal biologically active compounds in C. suaveolens oils were (Z)-en-yne-dicycloether (17.0 – 40.7%), (E)-β-farnesene (19.5– 32.2%), geranyl isovaleriate (8.4 –18.4%), palmitic acid (0.3 – 9.4%) and myrcene (1.1 – 7.9%). The investigation seems to approve the benefit of using aerial parts of pineapple weed as the substitute for flowers.
