Content and composition of essential oils in some Asteraceae species

Abstract

The content and composition of the essential oils of five Asteraceae species from Estonia were studied. The oil yields ranged from traces up to 0.2%. By using GC-FID and GC-MS methods a total of 115 compounds were identified and significant qualitative and quantitative differences were observed among the studied species. The main constituents of the essential oils of the studied Asteraceae species were as follows: Chamomilla recutita: bisabolol oxide A (39.4%), bisabolone oxide A (13.9%), (Z)-en-yne-dicycloether (11.5%), bisabolol oxide B (9.9%), α-bisabolol (5.6%), and chamazulene (4.7%); Chamomilla suaveolens: (Z)-en-yne-dicycloether (37.2%), geranyl isovalerate (22.9%), (E)-β-farnesene (15.6%); Anthemis tinctoria: α-eudesmol (10.2%), γ-cadinol (8.7%), γ-cadinene (4.0%); Matricaria perforata: (Z,Z)-matricaria ester (77.9%), (E)-β-farnesene (3.5%), matricaria ester isomer (3.5%), and matricaria lactone (3.0%); and Leucanthemum vulgare: (E)-β-farnesene (7.3%), hexadecahydrocyclobuta[1,2:3,4]dicyclooctene (5.3%), decanoic acid (4.9%), and γ-eudesmol (4.5%). The number of compounds found in all plant oils studied was 14.

Comparison of Compositions and Antimicrobial Activities of Essential Oils from Chemically Stimulated Agarwood, Wild Agarwood and Healthy Aquilaria sinensis (Lour.) Gilg Trees

“…AMDIS software was used to calculate Kovats retention indices. Further identification was made by comparing their mass spectra with these stored in NIST 08 and with mass spectra from the literature [ 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 ]. The relative concentrations of the components were obtained by peak areas normalization without applying correction factors.…”

“…Chamomilla recutita L. Rauschert, German chamomile), belonging to the Asteraceae family, is one of the well-known medicinal plant species which has been widely used for centuries. The herb is currently consumed around the world as herbal tea, with more than 1 million cups daily [1,2]. M. chamomilla is used in the treatment of many ailments and disorders; internally to facilitate digestion and as antispasmodic, externally to treat minor wounds.…”

Peruvian Botanical Biopesticides for Sustainable Development and Protection of the Environment

“…Plant-derived compounds that are rich sources of bioactive chemicals provide promising alternatives to the current use of chemical pesticides for insect control (Khalaf et al, 2009). The Asteraceae family constitutes an important source of secondary metabolites, such as monoterpenes, sesquiterpenes, sesquiterpene lactones, diterpenes, triterpenes, flavonoids, coumarins, polyacetylenes, and benzofurans (Raal et al, 2011;Alvarenga, Ferreira, Emerenciano & Cabrol-Bass, 2001;Ferreira, Brant, Alvarenga, & Emerenciano, 2005).…”
