The present study describes a simple, accurate, precise and cost effective UV-Visible spectrophotometric method for the estimation of Riboflavin raw material. The Riboflavin is water soluble vitamin, so the solvent used throughout the experiment was 0.1N NaOH, the absorption maxima of drug was found at 445 nm. Beer’s law was obeyed in the range of 5ppm-30ppm. the developed method was successfully validated with respect to linearity, accuracy and precision. The method was validated and shown linearity in mentioned concentration. The correlation coefficient for Riboflavin was 0.999. The percentage relative standard deviation of inter-day precision range 0.66-1.04% and intra-day precision 1.05-1.39% both should be less than 2%. Hence proposed method was precise, accurate and cost effective, simple and rapid. This validated method can be applicable for quantitative determination of the titled drug with respect to assay from or for their solid dosage...

Heterocyclic compounds are of very much interest in our daily life. Heterocyclic compounds have one or more hetero atoms in their structure. They may be cyclic or non cyclic in nature. Heterocyclic compunds have a wide range of application. They are predominantly used as pharmaceuticals, as agrochemicals and as veterinary products. They also find applications as sanitizers, developers, antioxidants, as corrosion inhibitors, as copolymers, dye stuff. They are used as vehicles in the synthesis of other organic compunds. Some of the natural products e.g. antibiotics such as penicillin’s, cephalosporin; alkaloids such as vinblastine, morphine, reserpine etc. have heterocyclic...

Plant polyphenols have been studied largely because of the possibility that they might underlie the protective effects afforded by fruit and vegetable intake against cancer and other chronic diseases. The objective of the present study is to estimate the total polyphenolic content in aqueous and methanolic extract prepared from the bark of Acacia nilotica plant species. Acacia nilotica (L.) Willd. ex Del commonly known as babul, kikar or Indian gum Arabic tree, has been recognized worldwide as a multipurpose tree. Mostly it occurs as an isolated tree and rarely found in patches to a limited extent in forests and has been widely planted on farms throughout the plains of the Indian subcontinent. The bark, root, gum, leaves and flowers have found use for skin diseases, diarrhoea, dysentery, cough, diabetes, eczema, wound healing, burning sensation and as an astringent, demulcent, anti-asthmatic. For present work the bark of well identified A. nilotica (L) plant for the extraction of phytochemicals was done from the village Khargawali (Hoshangabad district). 20-20 grams of the...

The ophthalmic in-situ gels now days proved an palpable sustained drug delivery in various eye diseases. The formulation of in-situ gels for eye which carries the advantages like easy for administration, reduces frequency of dose and improves patient compliance. The formation of in-situ gels depends on phase transition system or sol-gel transition system. The formulation approaches like temperature intonation, pH change and presence of ions from which the drug gets released in a sustained and controlled manner are utilised for in-situ gels. Various polymers that are used for the formulation of in-situ gels include chitosan, Pluronic F-127, poly-caprolactone, gellan gum, alginic acid, xyloglucan, pectin...

It is important to predict the serum thyroid hormones level in females during infertility to prevent its occurrence later on. In this study, we studied serum thyroid hormones and menstrual irregularities during infertility. A case control study was performed in 75 infertile patients with menstrual irregularities and 50 healthy matched women. Three biochemical parameters were measured in serum, hormones triiodothyronine (T3), tetra-iodothyronine (T4) and serum thyroid stimulating hormone (TSH) by TOSOH-AIA-360, immunoassay method. Out of 75 infertile women sixteen percent (16%) had menstrual irregularities with hypothyroidism. The mean serum thyroid level in 75 infertile women were 0.88±0.34 ng/ml, 7.69±2.87 μIu/dl and 5.43±6.88 μIu/ml, respectively. Serum T3, T4 and TSH level were statistically highly significant in infertile women. Serum thyroid stimulating hormone level was found at higher side in infertile women. High incidence of hypothyroidism was found in infertile women and it shows a positive correlation with menstrual...
