INTRODUCTION Diseses re the mjor use of eth in the eveloping ountries n ounts to 50% of it. Antimiroil gents re essentilly importnt in reuing the glol uren of infetious iseses. However, s resistnt pthogens evelop n spre, the effetiveness of the ntiiotis is iminishe. This type of teril resistne to the ntimiroil gents poses very serious thret to puli helth, n for ll kins of ntiiotis, inluing the mjor lst-resort rugs, the frequenies of the resistne re inresing worlwie [1]. Bteril resistne to ntiiotis inreses mortlity likelihoo of hospitliztion n length of sty in the hospitl [2]. Reently, there hs een lot of ttention fouse on prouing meiines n prouts tht re nturl. Severl fruits n fruit extrts, s well s rrowroot te extrt n ffeine, hve een foun to exhiit ntimiroil tivity ginst Esherihi oli O157:H7 [3]. This suggests tht plnts whih mnifest reltively high levels of ntimiroil tion my e soures of ompouns tht n e use to inhiit the growth of fororne pthogens. The teril ells oul e kille y the rupture of ell wlls n memrnes n y the irregulr isruption of the intrellulr mtrix when trete with plnt extrts [4]. Plnt-se ntimiroils represent vst untppe soure. The use of the plnt extrt for meiinl tretment hs eome populr when people relize tht the effetive life spn of ntiioti is limite n over-presription n misuse of tritionl ntiiotis re using miroil resistne [5]. Tritionlly use meiinl plnts proue vriety of ompouns of known therpeuti properties [6]. All meiinl plnts proue importnt seonry metolites suh s terpenois, flvonois, polyphenols, hlorophylls, n etlins. Among these, phenoli ompouns re onsiere to e the hief plnt onstituent euse of its pity to exhiit ntioxint, nti-nerous, n ntiinflmmtory properties [7]. In reent yers, ntimiroil properties of the meiinl plnts re eing inresingly reporte from ifferent prts of the worl [8]. At present, nerly 30% or more of the moern phrmologil rugs re erive iretly or iniretly from plnts n their extrts ominte in homeopthi or yurvei meiines [9]. Consiering the vst potentility of plnts s soures for ntimiroil rugs, this stuy ime to etet the ntiteril tivities of some nturl plnt extrts n investigte the effet of some ommeril ntiiotis ginst multirug resistnt humn linil teril isoltes. Mus umint, ommonly known s nn plnt, is vstly eing onsume ross the worl. It is known for mny phrmologil tivities n reports show tht nn leves ontin lrge mount of phenoli ompouns espeilly polyphenol oxise whih is use in the tretment of Prkinson s isorer [10]. The pomegrnte (Puni grntum) n nient, mystil, n highly istintive fruit elong to Puniee fmily. Chemil onstituents of the lef extrt of P. grntum re lmost similr to those of the fruit or see, e.g., ellgi i, tnnins (punilin n punifolin), n flvones glyosies inluing luteol in n pigenin. In previous stuy, it is reporte tht the ntiieti n ntihyperlipiemi effets of ethnoli extrt of P. grntum in lloxn-inue ieti rts [11]. Ppy (Cri ppy L.) is memer of Criee Fmily. The ppy is espeilly suseptile to prsites, pests, n iseses. This fussy

It hs een use to tret igestive prolems n intestinl worms s well s wrts, sinusitis, ezem, utneous tuerules n hrness of the skin. Green fruits re use to tret high loo pressure, rounworm infetion, yspepsi, onstiption, menorrhe, skin isese, generl eility, n genitourinry isorers [12]. The tritionl use of C. ppy leves in the tretment of vrious ilments inluing urinry trt infetions informe the nee for this stuy, whih ws ime t evluting the ntiteril tivity of the leves ginst some gents of urinry trt infetion. Guv (Psiium gujv) in meiine, extrts of leves re use to tret gstroenteritis, vomiting, irrhe, ysentery, wouns, ulers, toothhe, oughs, sore throt, inflme gums, n numer of other onitions. Guv leves ontin essentil oil with the min omponents eing α-pinene, β-pinene, limonene, menthol, terpenyl ette, isopropyl lohol, longiylene, ryophyllene, β-isolene, ryophyllene oxie, β-opnene, frnesene, humulene, selinene, rinene, n urumene [13]. This stuy ws rrie for sreening the ntiteril tivity of four fruits plnts use for the linil tretment y lol ommunities ginst some pthogeni teril strins. METHODS Survey n olletion of plnt mterils The fresh n helthy leves of nn, pomegrnte, ppy n guv were ollete from ifferent prts of Ghururi, Puri, Grhwl, Uttrkhn, Ini. Leves smples were rought to the lortory n thoroughly wshe in istille wter. Eh plnt mteril ws lele, numere n informtion regring te of olletion, meiinl use of plnt leves n lotion from were ollete reore. Plnt mterils were ientifie n ontminte prtiles were remove. They were ir-rie n groun into fine power using mortr n pestle in the lortory [14]. Preprtion of leves extrts The leves extrt of totl four fruits plnt were ir rie, hoppe n gin she rie for 14 ys t room temperture n then groune lef power using griner for ese of the extrtion of tive ompouns. The powere plnt mteril (15 g) ws pke into soxhlet pprtus n extrte up to 4 hrs with ethyl ette (250 ml) t C for eftting [15]. The extrt ws filtere, n the solvent ws evporte uner reue pressure using rotry vuum evportor t 65 C. These purifie extrts were then store t 4 C until further use. Antimiroil ssy Bse on their linil n phrmologil importne, Billus sutilis, E. oli, Stphyloous ureus, n Pseuomons eruginos were hosen for evluting ntiteril tivity. These teril strins otine from Institute of Miroil Tehnology, Chnigrh, n fungl isoltes from Forest Reserh Institute, Dehrun. The teril stok ultures were inute t 37 C for 24 hrs on nutrient gr n fungl pthogen Peniillium oxlium n Alternri lternte on potto extrose gr (PDA) t 27 C for 24 hrs followe y storge t 4 C until further use. A totl of four plnt extrts were use in this stuy to sreen their ntimiroil tivity. Antiteril suseptiility testing ws one using the well-iffusion metho. The plnt extrts were teste on Mueller-Hinton Agr pltes to etet the presene of ntiteril tivity. All pltes were inoulte with the test terium, sterile otton sw ws ippe into the suspension, rotte severl times, n presse firmly on the insie wll of the tue ove the flui level removing exess inoulum. The surfe of the gr plte ws streke over the entire sterile gr surfe rotting the plte to ensure n even istriution of inoulums. After spreing the pltes with teri, 5 mm imeter wells were punhe into the meium using sterile orer. The pltes re llowe 3-5 minutes to ry the exess moisture. 50 μl liquots of eh test extrt were ispense into eh well-fter the inoultion of the pltes with teri. For eh teril strin, ontrols were mintine where pure solvents were use inste of the extrt. The pltes re sele with prfilm, lele, n ple in n inutor set to 37 C. After 24 hrs of inution, eh plte ws exmine for inhiition zones. A ruler ws use to mesure the inhiition zones in mm. Determintion of minimum inhiitory onentrtion (MIC) MIC ws etermine fter ntiteril tivity of the plnt lef rue extrts y the stnr metho with minor moifition. Muller- Hinton Broth ws me n sterilize using utolve. 1.0 ml of the prepre roth ws ispense into the test tues lele from 1 to 5 using sterile syringe n neele. A stok solution ontining 60 mg/ml of the extrt ws prepre. Then, 1.0 ml of the solution ws ispense into the tue 1. Susequently, from tue 1 solution ws serilly trnsferre until tue ml of the solution ws isre from it. Tue 6 ws use s ontrol for sterility of the meium n tue 7 for viility of the orgnisms. An overnight ulture of eh of the test isoltes ws prepre in sterile nutrient roth. 1 ml inoulum ws trnsferre into eh tue from tue 1 to tue 7 with exeption of 6, to whih nother sterile roth ws e. The finl onentrtion of the extrt in eh of the test tues numere fter ilution 60, 30, 15, 7.5, 3.75 mg/ml ws inute t 37 C for 24 hrs n exmine for growth. The test tue in whih growth file to our ws the MIC of the ulture. Antifungl tivity ssy PDA meium with 25% onentrtion of the solvent extrts of the test fruit plnts ws prepre. Aout 15 ml of the meium ws poure into eh Petri plte n llowe to soliify. 5 mm is of 7-y-ol ulture of the pthogeni fungi ws ple t the enter of the Petri pltes n inute t 27±2 C for 7 ys. After inution, the olony imeter ws mesure in millimeter. PDA meium without the solvent extrt serve s ontrol. The fungitoxiity of the extrts in terms of perentge inhiition of myelil growth ws lulte y using the formul % Inhiition = -t/ 100 Where = Averge inrese in myelil growth in ontrol, t = Averge inrese in myeli growth in tretment [16]. Phytohemil sreening of fruits leves rue extrts Phytohemil nlysis tests for the sreening n ientifition of iotive hemil onstituents of extrts of the fruits lef were performe with the stnr methos with moifitions [17]. Test for sponins Aout 1 ml liquots of the vrious plnt lef extrts were omine with 5 ml wter whih is t 60 C then shken for 2 minutes s sponins re known to proess frothing tivity, the volume of froth proue in this experiment ws oserve.
