Objective: Bosenbergia longiflora (wall.) Kuntze is a rhizomatous plant of family Zingiberaceae which has been traditionally used for curing many diseases like inflammatory bowel disease, ulcerative colitis, aphthous ulcer,antiinflamatory, healing of wound etc. The present work is aimed at phytochemical profiling, especially terpenoids, of rhizome essential oil of Bosenbergia longiflora (wall.) Kuntze using gas chromatography and mass spectrometry (GC-MS) analysis.Methods: The essential oil from mature fresh rhizome was extracted by hydro distillation method by using Clevenger's apparatus. GC-MS analysis of essential oil was carried out to identify major volatile constituents.Results: The present work revealed that the oil was highly rich in longipinocarvone, a sesquiterpenoid, as major compound (81.69%). The oil also contained trans-caryophyllene (1.54%), β-Cis caryophyllene (3.41%), patchoulene (2.97%), borneol (2.32%), limolene (1.5%) etc. GC- MS detected 13 compounds out of which 12 compounds could be identified.Conclusion: GC-MS analysis of Bosenbergia longiflora revealed an abundance of longipinocarvone which may responsible for many activities it possesses. The percentage of longipinocarvone being higher in this plant, it could be explored for various pharmaceutical uses.Â
