    Abstract

    Essential oils e+tracted from floer (etals of (almarosa -Cymbopogon martini, evening

    (rimrose -Primula rosea, lavender -Lavandula angustifolia and tuberose -Polianthustuberosa ere tested for their antibacterial activities against gram/(ositive and gram/

    negative bacteria. 0ifferent concentrations of each essential oil ranging from 12/1223

    ere tested. !oth gram/(ositive and gram/negative bacteria ere found susce(tible to thestudied floer essential oils. 4ith increase in concentration of essential oil, increase in

    5one of inhibition as observed thus dose/de(endent res(onse as clear for each

    essential oil. Essential oil e+tracted from Cymbopogon martinishoed the highestactivity against both gram (ositive and gram negative bacteria among the tested essential

    oils.

    "olatile com(ounds from (lants, es(ecially essential oils have antimicrobial, fungicidal

    and insecticidal activities61,78. The essential oils are strong antimicrobial agents ith

    broad s(ectrum activity ith (ossible (otential for the control of (athogens in (lants as of(ost/harvest s(oilage of many cro(s and also to human (athogenic diseases698. They may

    (rove to be more economical and environmentally safe, as an antimicrobial agent.

    The volatile essential oils released from leaves, floers and fruits into the atmos(here

    and from roots into the soil defend herbivores and (athogens6:8. Essential oil from floer

    (etals of Palmarosa is used for gargles in throat infection, and s$in care678. Evening(rimrose is ell $non for s$in care and beauty treatments in Ayurvedic medicines6;8.

    Tuberose is an ornamental (lant, hich is idely used in aeromathera(y because of its

    flavour and fragrance68.

    Plant essential oils constitute about 13 of (lant secondary metabolites and are mainly

    re(resented by ter(enoids, (henyl(ro(anoids or ben5enoids, fatty acid derivatives andamino acid derivatives6:8. Earlier or$ers have isolated some (otent constituents li$e
