Leaves Essential Oil and its Antimicrobial Activity Nosiba Hassan Elsheikh Idris A Ph.D. in Oil Chemistry (August , 2013) National Oil Seed Processing Research Institute (NOPRI) University of Gezira ABSTRACT Lantana camara (L), of the family Verbenaceae, is listed as one of the important medicinal plants of the world. The plant is an evergreen aromatic plant, found in tropical and subtropical areas around the world. In Sudan it is commonly grown as an ornamental plant and displays several flower colors combing different shades of red- yellow- purple- violet- white- orange and yellow and orange. The essential oil of Lantana camara showed a wide spectrum of antibacterial, antimicrobial, and antifungal activities. The aims of this study were to evaluate chemical composition of locally grown Lantana plants, to evaluate their content of leaf essential oil and to assay biological activities of crude and purified constituents of the essential oil against a selected bacterium and a fungus. The plants, collected from the Gezira area around Wad-Medani, were extracted by using hydro- distillation method and cold extraction technique. The crude essential oil extracts of lantana Camara Var. aculeata were tested for growth inhibition of Agrobactrium tumefaciens and Aspergillus niger using the disc diffusion method and well fungal- growth disc diffusion method. Chemical fractionations and component identification were performed using TLC, PTLC, GC/MS, MS, UV, and FTIR. The results indicated that the crude essential oils of lantana Camara Var. aculeate possessed considerable antibacterial activities, with lethal concentration (LC50) between 160- 200μl/ml and minimum inhibitory concentration (MIC) between 4 and 8 μl/ml. On the other hand, the essential oil showed significant antifungal activity resulting in 100% kill at doses of 280 and 300 μl/ml, and LC50 of 160μL/ml, and 8-12μL/ml for MIC. Of nine separated components, eluted from PTLC-plate, only two (C1 and C6) were found active against A. niger (causing antifungal inhibition of 14% and 55% respectively). The major constituents of the essential oil of Lantana camara dependent on GC/MS were limonene, C6-Ketone, the sesquiterpene -cayrophyllene, representing more than 30% of the oil. Compared with Iran(14%), China(12%), and Nigeria(13%). vi المكونات الكيميائية للزيت الطيار من أوراق الﻻنتانا وتضاده الميكروبي نسيبة حسن الشيخ إدريس دكتوراه الفلسفة في كيمياء الزيوت )أغسطس 2013م( المعهد القومي لبحوث تصنيع الحبوب الزيتية )نوبري( جامعة الجزيرة الخﻻصة نبات الﻻنتانا .Lantana camara L أحد النباتات الطبية والعطريةة الااةةة ةل العةالي ونةل تنت ةل للعائلة الفيربينية وتوجد ل ال ناطق ذات ال ناخ ال عتدل وغير ال عتدل حول العالي. ل السةواا تةع ك بنبةات للعينةة حةول ال نةةا ل وتت يةع بالواناةةا ال تلفةة التةةل ت تةون سلةة البنفسة – اﻷصةةفر – الةو ان – اﻷح ةةر – اﻷبةةي – البرتقةةالل – اﻷصةةفر والبرتقةةالل. أااةةر العيةة الطيةةا لﻻنتانةةا ةقةةد ساليةةة للت ةةاا الب تيةةرن وال ي روبل والفطرن. الادف ةن نذه الد اسةة نةو تقيةيي عاليةة العية العطةرن ال ةا وة وناتة دةد النطةاط اﻹحيائل و تي تصنيف النبات بنا ًء سل لةو اﻷ نةا ولة ل السةاب ﻹ باﻹدةا ة ل عر ةة النسةبة ال زويةة للعية الطيا ل أنواك اﻷ نا ة تلفة اﻷلوا . تي ج ع أو اب الﻻنتانةا ةةن حةول ةدينةة واةةدنل ةل وجيةة ال عيةر واسةةت لا العيةة ةناةةا بواسةةطة طريقةةة التقطيةةر ال ةةائل وباجسةةت ﻻب البةةا ا ﻹ تةةي ااتبةةا عاليةةة العيةة ال سةةت لا ةةةن Lantana camara var. aculeata دةةد ب تريةةا العقةةد ال ذ يةةة Agrobacterium tumefaciens و طر العفن اﻷسوا Aspergillus niger باسةت دا طريقةة اجنتطةا سةن طريةق نةرب ةةن الةةو ب وبطريقةةة اجنتطةةا سةةن طريةةق نةةرب نةةاةل ةةةن الفطةةر ةةل اﻷجةةا . أجريةة ت اليةةل بي يائيةةة ل عر ةةة ال ونات الرئيسية للعي الطيا لعدا تسع سينات ةن الﻻنتانا باست دا )بروةاتوجرا يا الغا /ةطيا ية ال تلةة وةطيا ية ال تلة ب ا ت ةعر ة نوية ال ربب الفعال باست دا ةطياف اﻷلةعة ت ة ال ةراء ال ةعوا ب ةول و ييةﻹ ةطيا ية اﻷلعة وب البنفس يةﻹ بروةاتوجرا يا الطبقة الرنيقةﻹ )بروةاتوجرا يا الغا /ةطيا ية ال تلة وةطيا ية ال تلة. ألا ت النتائ إل أ ي الﻻنتانةا الطيةا أبةدع عاليةة دةد الب تريةا و صةدت ني ةة جرسةة التربيةةع القاتلةةة LC50 وبانةة بةةين 160-200 ةةةاي روليتر /ةةةل ب ةةا صةةدت ني ةةة ال ةةد اﻷانةة للقتةةل MIC وبانةة بةةين 4-8 ةةةاي روليتر /ةةةةل. أةةةا الفطةةر قةةةد وصةةل نسةةبة القتةةةل إلةة 100% سنةةد ال رسةةةات 280 ةاي روليتر /ةةل و 300 ةةاي روليتر /ةةلﻹ أي ةاً صةدت ني ةة LC50 وبانة سنةد ال رسةة 160 ةةاي روليتر /ةل و MIC وبان بين 8-12 ةاي روليتر /ةل. تي صل تسعة ةرببات للعي الطيا Lantana camara var. aculeata ب روةات را يةا الطبقةة الرنيقةة ووجةد أ ا نةين قة (C6, C1) لا ةا عاليةة دةد طةر العفةن اﻷسوا بنسبة 14% و55% سلل التوالل وند وجد أ ال ونات الرئيسية للعي الطيا لﻻنتانا نةل الﻻي ةونين و ك6-بيتو و سس وتربين بيتا با يو يللين (β- caryophyllene) والذن تفوب نسبت 30% ةقا نة بالنسةبة ال وجوا ل إيرا 14% والصين 12% وني يريا %13. vi LIST OF CONTENT Page Declaration ……………………………………………………………….. iii Dedication …………...…………………………….……..……..………... iv Acknowledgements …..…………………………..…………..…………... v English Abstract …...…..………………………………….……..……...... vi Arabic Abstract ………...………………………………………….……... vi List of Contents............................................................................................ vii List of Tables ….......................................................................................... viii List of Figures….......................................................................................... ix List of Abbreviations……………………………………………………... x CHAPTER ONE:…………………………………………..……………. 1 1.
