2a: Infrared Spectroscopy and Analgesic Drug Identification Abstract: To be able to understand how organic soluble compounds could be isolated from non-organic components‚ a chromatographic separation process was used. The objective of the analgesic drug identification is to isolate the organic compounds/ active ingredients in an unknown drug. The identity of the drug was determined through melting point‚ percent recover‚ and Rf values. The comparable data for acetaminophen from the manufacturer

Objectives of the Study This study evaluates the genotoxicity‚ and teratogenicity/antiteratogenicity of the methanol leaf extracts of Tamarindus indica (TE). In particular‚ the study aims to: determine the genotoxicity of TE in terms of: mitotic index chromosomal aberrations micronuclei formation assess the developmental toxicity and teratogenicity potential of TE to zebrafish embryos; and verify the potential of TE to rescue zebrafish embryos from ethanol-induced teratogenicity.

CHAPTER I INTRODUCTION 1.1 HISTORY: Ethylene Glycol (1‚ 2 – ethanediol)‚ HOCH2CH2OH usually called glycol is the simplest Diol. Diethylene glycol and Triethylene glycol are Oligomers of Mono ethylene glycol. Ethylene glycol was first prepared by Wurtz in 1859; treatment of 1‚2 dibromoethane with silver acetate yielding ethylene glycol diacetate via saponification with potassium hydroxide and in

Background of the Study Tea is created by using the leaves of a plant known as Camellis sinensis. This plant is native to mainland China‚ South and Southeast Asia‚ but it is today cultivated across the world in tropical and subtropical regions. It is an evergreen shrub or small tree that is usually trimmed to below 2 m (6.6 ft) when cultivated for its leaves. It has a strong taproot. The flowers are yellow-white‚ 2.5-4cm (0.98-1.6 in) in diameter‚ with 7 to 8 petals. Tea-drinking can be traced back

methosulfate (186 μM)‚ 0.3 ml of nitro blue tetrazolium (300 μM) and 0.2 ml of NADH (750 μM) were mixed together. The reaction started by addition of 0.2 ml of NADH. After incubation at 30 ̊C for90s‚ the reaction stopped by the addition of 0.1ml of glacial acetic acid. 2.10.
