Abstract

Medicinal plants are of great importance to the health of individuals and communities in general. The major constituent found to be Citronellol present in the essential oil. Taraxacum mitalii was collected from two different locations of Uttarakhand, essential oil was extracted from the leaf sample using hydro-distillation method, Gas chromatography coupled with mass spectrometer was used for chemical analysis of the extracted essential oil. Total of 64 constituents were identified from two essential oil of Taraxacum mitalii representing 97.5%, 88% of the total oil collected from Nainital, Ranikhet region. Monoterpene were Citronellol (21.93%), Geraniol (18.62%), β- Linalool (9.09%) and Iso- Menthone (5.89%) as a major component. Second constituents were sesquiterpene (24.21%) with 32 compounds. The major components of sesquiterpene were γ.- Eudesmol (5.59), Citronellyl formate (4.40), Geranyl tiglate (3.80%), Viridiflorene (2.03%) and β-Bourbonene (1.88%).
