3.1 Overview The experiment was divided into three parts. In the first part was the preparation of empty CNPs. The second part was the preparation of CNPs loaded with single drug which was AA and TQ meanwhile the third part was the preparation of CNPs loaded with dual drug (AA and TQ). The last part was the analytical testing conducted to investigate the properties performance such as smaller or larger in trend as well as to characterize the entrapment efficiency of drugs. The chemicals and technique

swab stick was dipped into the test tube containing the organisms and it was used to seed the organism on the solidified Muella Hinton agar. The prepared disc was transferred on the the inoculated culture plates. The placed disc included 100mg/ml (DMSO) and gentamycin 2mg/ml.The plates were incubated for 24hours at 37oC‚ after which the zone of inhibition was measured and recorded. The test was carried out in duplicate. | 10. Analysis of data (results). What are the statistical tools used? |

Introduction Chemists often find a method to determine the level of “greenness” of a chemical reaction‚ or its “atom economy”. A higher atom economy is preferable because a greater amount of the reactants will be present in the product as opposed to the byproduct.1 A Suzuki reaction is classified as an organic‚ coupling reaction that includes boronic acid and a halide that are catalyzed by a palladium complex under basic conditions. Other palladium- catalyzed coupling mechanisms include the Heck

INTRODUCTION Cassia fistula Linn. (Leguminosae) is a very common plant and is widely known for its medicinal properties. In the Indian literature‚ this plant has been described to be useful against skin diseases‚ liver troubles‚ tuberculous glands and its use in the treatment of rheumatism‚ hematemesis‚ pruritus‚ leucoderma‚ and diabetes.[1‚2] Besides‚ it has been found to exhibit anti-inflammatory and hypoglycemic activity and widely used as a mild laxative suitable for children and pregnant women

M5 (4.54 g‚ 17.2 mmol) and sodium 6-oxidonaphalene-2-sulfonate (0.84 g‚ 3.13 mmol) were dissolved in 30 ml of DMSO. The mixture was stirred at room temperature overnight. The mixture was poured into ice cold acetone with continuous stirring. The mixture was filtered and washed with DCM and methanol to yield the title compound as pale yellow solid.

Experimental Synthesis of Bupropion – A round bottom flask (RBF) containing m-chloropropiophenone (1.0 g‚ 5.9 mmol) dissolved in 5.0 mL dichloromethane (DCM) with 0.25 mL of 1.0 M Br2 in DCM was briefly warmed to initiate the bromination reaction. Afterwards‚ the RBF was placed in and ice-water bath and 1.0 M Br2 in DCM (6.0 mL‚ 6.25 mmol) was added dropwise while stirring. DCM was removed from the reaction by rotary evaporation.
