Antimicrobial Activity and Composition of Rindera lanata (LAM.) Bunge var. canescens (ADC) Kosn. Essential oil Obtained by Hydrodistillation and Microwave Assisted Distillation
Özet
The composition of essential oils of Rindera lanata (LAM). Bunge var. canescens (A.D.C) Kosn. obtained by hydro-distillation (HD) and microwave assisted distillation (MW) by GC, GC/MS. Thirty three and thirty nine compounds were identified in the oils representing 81.20% and 78.57% of the oils obtained by HD and MW respectively. Aldehydes were shown to be the main group of constituents of the MW 40.11% and 15.23%, respectively. However, the major group in the HD was found to be 25.35% alcohols and 23.78% hydrocarbons. 6-Methyl heptan-2-ol (15.97%) was the main compound of the HD. Furthermore, in the MW assisted essential oil, the major compound present was decane (10.50%). Terpenoid class compounds were found in essential oils and oxygenated monoterpenes were determined as major group (13.34% and 7.19%). Antimicrobial activity of the isolated essential oils of the plant was also investigated and they showed moderate antimicrobial activity against the tested microorganisms.
