The identification and quantification of the volatile organic compounds profile of the plants is an important tool for food quality and authenticity assessment. In that context, herewith the study, we aimed at quantifying the volatile compounds of three plants Artemisia campestris L. subsp. glutinosa, Lavandula angustifolia Mill., and Zingiber officinale Rosch using Gas Chromatography-Mass Spectrometry (SPME/GC-MS). Thirty-three volatile compounds were revealed with SPME/GC-MS. Of the identified compounds, α-curcumene (34.41%) and eucalyptol (20.91%), were predominant compounds in Zingiber officinale Rosch. For Artemisia campestris subsp. glutinosa, camphor (31.78%), and α-thujone (16.82%) were noted as the most abundant volatile compounds. Besides eucalyptol (15.10%), and linalool (11.98%) were recorded as major volatile compounds in the Lavandula angustifolia Mill.
Secondary metabolites, especially essential oils are of the widely used phyto-chemicals for various purposes. In this regard, numerous studies have been reported on profile of these reputed metabolites in medicinal and aromatic plant (MAPs) species. Of the substantial family of the MAPs, Lamiaceae is of the reputed group with a notable number of plant species. Regarding the species of this group, sage (Salvia officinalis) and rosemary (Rosmarinus officinalis) are of the well-known and widely-studied species. Herewith the current study, we profiled the essential oil composition in leaves of both species. Accordingly, the analysis revealed that camphene (29.40%), 1,8-cineole (37.26%), camphor (13.48%), borneol (3.69%), trans-caryophyllene (5.42%), and α-thujone (5.78%) were of the predominant compounds identified for S. officinalis, whilst camphene (22.45%), 1, 8-cineole (35.36%), linalool (3.67%), camphor (10.80%), cyclohexane,(1-methylethylidene) (3.09%), α-fenchyl alcohol (3.03), 2-cyclohexen-1-one, 2-methyl-5-(1methylethenyl) (2.12%), and endo-bornyl acetate (4.50%) were of the principal components in leaves of R. officinalis.The next studies on the relevant species might be focused on the biological activity of the essential oils.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
