Abstract:

The rhizomes of Hedychium coronarium species were subjected to extraction of essential oil as secondary metabolites by the hydrodistillation method. A total of eleven components were revealed in the essential oil by GC/ GC-FID and GCHRMS analysis. Eucalyptol was the major component of oil along with α-terpinol and βpinene. Out of four tested bacteria (two gram +ve and two gram –ve), the oil showed excellent antibacterial activity versus E. coli while the preeminent antifungal potency was found against C. albicans. The excellent antimalarial efficacy of oil was observed against Plasmodium falciparum. To the best, the presence of –(a) 1,4- cineole, (b) Bicyclo[2,2,1] heptan-3-one,6,6-dimethyl-2methylene,(c)7,11Dimethyldodeca-2,6,10-trien-1-ol(E,E) and (d)1-terpinol in Hedychium coronarium are reported first time for Konkan region in this study.
