Exploration of Wild Cymbopogon citratus (DC.) Stapf. for Fingerprint Compounds in Volatile Oil

摘要

The wild Cymbopogon citratus (DC.) Stapf. collected from Janabharathi campus, Bangalore University, Bengaluru was subjected to hydrodistillation method and essential oil extraction was carried out. The GC-MS analysis was performed and the chemical composition of the essential oil was determined. A total of 45 fingerprint compounds were found in the essential oil out of which geranial (53.07), Trans-p-mentha-2-8-dienol (3.12), Cis-p-mentha-2-8-dienol (2.24), Verbenol (2.92), Geranyl acetate (2.34), Geraniol (2.17), D-limonene (1.79) and linalool (1.30) were present in higher percentages. The essential oil biosynthesis of terpenoid compounds consisted of mono, di and sesquiterpenes. These terpenoid compounds play important role in plant development and serve as potential compounds showing varied bioactivities.
