CHAPTER ONE 1.0 INTRODUCTION 1.1 Antimycobacterial Studies An Antimycobaterial is a substance that kills or inhibits the growth and activities of disease causing Mycobacteria (e.g.‚ Mycobacterium tuberculosis‚ Mycobacterium Leprae‚ etc) that are responsible for fatal diseases such as Tuberculosis and leprosy. Antimicrobacterials can either kill microbes (microbiocidal) or prevent the growth of microbes (microbiostatic) (Hannan et al.‚ 2011). Mycobacterium is a genius in the family of the Mycobacteriaceae

1. Introduction Plumbago zeylanica L. belonging to the family Plumbaginaceae is an important plant of medicinal value. In the Arabian Peninsula‚ it is mainly distributed over Oman‚ Yemen and the Southwestern region of Saudi Arabia. The use of the roots of P. zeylanica for treating skin problems has been recorded by early Muslim physicians. P. zeylanica is greatly valued in Ayurveda for treatment of cough‚ asthma and gastrointestinal disorders. In Sushrutha Samhitha it has been described as antiseptic

The developing chamber is a critical technique of TLC for it becomes the principal reference to recording the Rf values of the solutions. 5ml of Ethyl Acetate Acid was poured inside a 250ml beaker. As stated in the introduction‚ CH3COOCH2CH3 was the developing solvent in our chamber for this solution. The beaker was then covered with a piece a foil and places under a hood. This was done so that the chamber

Abstract: Stevia rebaudiana is an herb with a very high medicinal value. It has more than 100 phytochemicals. It is used as sugar substitute. The extracts from leaves are used for the microbial assay and study the antimicrobial activity. The microbes used for the testing the activities are E.coli‚ Staphylococcus aureus‚ Bacillus subtilis‚ Salmonella typhi‚ Aspergillusniger‚ Candida parapsilosis‚ Trichophyton rubrum. With different concentrations of the extracts starting from 2.5µg/ml‚ 5.0µg/ml‚ 7

vacuum filtration‚ crystals will be held on a filtration paper while the liquid portion of reagents will drained into an Erlenmeyer flask. To purify our crystals even more‚ we will have to perform a procedure called re-crystallization‚ using ethyl acetate as our solvent instead of water in order to prevent decomposition of our products‚ and then once again we will use vacuum filtration to separate the crystals from the solvent. After we have finished with the experiment‚ we will be testing for

meantime‚ a dark green layer was seen attached to the top of the upper sea sand layer‚ which meant that there were pigments with higher polarity in the extract that did not dissolve substantially in hexane. Upon the addition of 10 mL of hexane: ethyl acetate (1:1)‚ a green solution was immediately formed above the sand level. As this solution entered the column‚ three colour bands were formed. The lowest was green‚ and the second lowest was yellow. However‚ these two bands were very close together

filtered using a Buchner or Hirsch funnel and was washed with three small portions of cold water. The crystals were allowed to air dry for several minutes while suction continued to eliminate excess water. The crude product was recrystallized from ethyl acetate. The dried crystals were weighed and a melting point was obtained.

Lab 3: Solubility of Organic Compounds Objectives: Understanding the relative solubility of organic compounds in various solvents. Exploration of the effect of polar groups on a nonpolar hydrocarbon skeleton. Introduction: The solubility of a solute (a dissolved substance) in a solvent (the dissolving medium) is the most important chemical principle underlying three major techniques you will study in the organic chemistry laboratory: crystallization‚ extraction‚ and chromatography.
