Abstract
A simple, sensitive, rapid, robust and reproducible method for the determination of Quetiapine fumarate in bulk and pharmaceutical formulation (Tablets) was developed using reverse phase high performance liquid chromatographic method (RP-HPLC). The RP-HPLC analysis was performed isocratically on XTERRA C18 (4.6X150mm), analytical column using a mobile phase consisting of ortho phosphorus buffer and acetonitirle in the Ratio of 60:40v/v, with a flow rate of 0.6ml/min. The analyte was monitored with UV detector at 290nm. The developed method Quetiapine fumarate elutes at a run time of 10 min. The proposed method is having linearity in the concentration range from 40 to 80 μg/mL of Quetiapine fumarate. The present method was validated with respect to system suitability, linearity, precision, limit of detection (LOD) and limit of quantification (LOQ), accuracy (recovery), ruggedness, and robustness. The proposed method can be readily utilized for bulk drug and pharmaceutical formulations.

Abstract
Oxidation is a natural process that occurs anytime a substance combines with oxygen like the browning of sliced apples or rusting of metals. When it occurs constantly, putting our health at risk. Antioxidants are substances that may protect cells from the damage caused by unstable molecules known as free radicals. Free radical damage may lead to cancer. Antioxidants interact with and stabilize free radicals & may prevent some of the damage free radicals otherwise might cause cancer. Antioxidants are abundant in fruits and vegetables, as well as in other foods including nuts, grains ands some meats, poultry and fish. The battle to conquer cancer is an international effort for the treatment of cancer. Currently we have about 30 chemotherapeutic agents and out of these nearly one third are natural products.The aim of this review is to know that how might antioxidants prevent cancer. So prospective study of antioxidants, & its mechanism and potential  use in cancer therapy is presented.

Abstract
This paper describe a simple, precise and economical spectrophotometric method for the quantitative determination of spironolactone (SPL) in tablet dosage form. Method is based on the estimation of SPL in 50 % v/v methanol in distilled water at 238 nm. Beer’s law was obeyed in the concentration range of 2-24 µg/ml. The accuracy of the method was assessed by recovery studies and was found to be 100.55±1.27 for SPL. Results of the analysis were validated statistically so that it can be used for routine analysis of SPL in tablet dosage form.
