rotundus was evaluated for its hepatoprotective activity in rats by inducing liver damage with carbon tetrachloride. The ethyl acetate extract which was administered orally at a dose of 100 mg/kg exhibited significant protective effect by lowering serum levels of the liver enzymes such as alanine aminotransferase (ALT or SGPT)‚ aspartate aminotransferase (AST or SGOT)‚ alkaline phosphatase

boiling points of two different substances are very different. Fractional distillation is the separation of a mixture of multiple components into its various fractions according to the difference in their boiling temperatures. a.) Hexyl acetate and butyl acetate- Simple distillation should be used for these two compounds because their boiling points are very different. b.) Hexanol and cyclopentanol- Fractional distillation should be used because there is a small difference of boiling points between

mL iodine flask. To the oil in the iodine flask‚ add 10 mL of dichloromethane acting as a solvent and mix by swirling gently. Add 20 mL of iodine monochloride solution from a burette and mix. Then add about 5 mL of a 2.5% solution of mercuric acetate in glacial acetic acid‚ which will act to catalyse the reaction. Insert the stopper which has been previously moistened with a solution of potassium iodide. Keep in a dark place for 3 minutes to allow the unsaturated fatty acid residues of the

bottom and sides of the flask so a spatula will probably be needed to scrape them out. Washing the flask and crystals with ice- cold xylenes completes this process. The resulting dried product was recrystalized using hot ethyl acetate. A hot plate was used to boil ethyl acetate to be poured into a heating beaker with a mixture of EtoAc and adduct until the product dissolved. A sequential suction filtration completed this

Title: Determination of Iron in Natural water by Spectrophotometry. Aim: To determine the iron in natural water by spectrophotometry. Abstract: The iron in natural water was determined by utilizing spectrophotometric analysis. That was done by measuring the absorbance of five Fe(oPH)2+3 standards at 510 nm. From that information‚ a calibration curve was plotted and used to find the amount of Fe2+ that was in two unknown water samples based on the absorbance readings obtained with them at 510nm. The

Experiment 2: Starch Hydrolysis by Amylase Theoretical Background Polymers of carbohydrates are called polysaccharides‚ and make up some of the most important naturally occurring compounds [1]. They have thousands of monosaccharide units linked to each other by oxygen bridges. They include starch‚ glycogen‚ and cellulose‚ all three of which yield only glucose when completely hydrolyzed [2].
