VOLATILE COSTITUETS, ATIBACTERIAL AD ATIOXIDAT ACTIVITIES OF ESSETIAL OIL FROMARDOSTACHYS JATAMASI DC. ROOTS

Summary Essential oil ofardostachys jatamansi DC. roots was extracted by hydro distillation and analyzed by GC&MS. Out of 26 compo nents, 8 were identified from their fragmentation pattern. Identified Components were ledene oxide(II) (13.021%), patchouli alcohol(9.582%), (&)&spathulen ol(2.672%), globulol(1.876%), 4&(3,3&dimethyl&but&1&ynyl)&4&hy droxy&2,6,6&trimeth ylcyclohex&2&enone(1.849%), magastigma&4,6(E), 8(Z)&triene(1.015%), aristolene( 0.997%) and β & vatirenene(0.932%). These components were identified first time from essential oil of �. jatamansi DC. roots The antibacterial activity of the essential oil of �. jatamansi was determined by paper disc diffusion method against both Gram positive and Gram negative bacteria ( Bacillus subtilis ATCC6633 , Staphylococcus aureus, Klebsiella pneumoniae , Salmonella typhimurium , Pseudomonas aeruginosa, Pseudomonas fluorescens, and Enterobacter aerogenes ). Among Gram positive bacteria �. jatamansi essential oil exhibited maximum antibacterial activity against B. subtilis followed by S. aureus .
