Invitro antimicrobial activity of hydrodistilled extract of Nardostachys Jatamansi rhizome

Abstract

The present study was designed to examine in vitro antimicrobial activities of the essential oil of Nardostachys Jatamansi. The major constituents of the essential oil were determined as Jatamansone (21.4%) and Isovaleric acid (13.4%). The antimicrobial activity of the oil was also tested against gram-positive and -negative bacteria and fungus using a disc-diffusion method and the minimal inhibitory concentration (MIC) values. The essential oil was tested Staphylococcus aureus, Bacillus subtilis, Corynebacterium diphteriae, Salmonella thyphi, Klebsiella pneunomonia, Proteus vulgaris, Escherichia coli and Pseudomonas aeruginosa and Candida albicans. The oil showed remarkable antimicrobial activity against all mic.
