Abstract: Magnesium Aluminate (MgAl2O4) and Magnesium Zincate (MgZnO4) nanoparticles were synthesized by solution combustion method, which were used as photocatalyst for the degradation of water containing direct green 6 (DG6). These synthesized nanoparticles were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), UV-absorption spectroscopy and FT-IR spectra studies. It was calculated that the corresponding band gap was found to be 2.9eV and 3.07eV respectively and also average crystalline size was found to be 13nm and 28nm. Photocatalytic degradation was determined against DG6 by varying parameters such as, catalyst concentration, pH, and dye concentration. From these experimental results we know that, the maximum degradation was found to be 97.99% for MgAl2O4 nanoparticle and 94.64% for MgZnO4 nanoparticle. Hence the efficiency of photodegradation of DG6 dye by using MgAl2O4 and MgZnO4 nanoparticles was ascertained.

Keywords: Direct Green 6, MgAl2O4, MgZnO4, degradation.

Abstract: The effect of graded doses (50, 100 and 150mg/kg body weight) of crude ethanol extract of the dry seeds of Piper guineense Schumach and Thonn was investigated on the ovary, liver, hormonal and some biochemical parameters of female rats weighing between 150-190g. Twenty rats were randomly divided into four groups of five rats each per group, group A (control) were orally dosed once daily with 1ml of distilled water (vehicle) while the test groups i.e. B, C and D were orally dosed with 50, 100 and 150mg/kg body weight of the crude extract in 1ml of the vehicle. After twenty one (21) days of the extract dosing samples were collected for analysis.The results are expressed as the mean of five replicates ± standard deviation, means were analyzed using one way analysis of variance (ANOVA) followed by Posthoc Turkey............

Abstract: Recently bio-based polymers have received great importance due to their eco-friendly properties towards environment. As a substitute of conventional reinforcing synthetic polymer, bio-based polymers were from renewable resources like cardanol, i.e., the meta-substituted phenolic compound the chief product of CNSL. A number of IPNs have been synthesized by condensing di-azotised-4-amino benzoic acid and 3-amino benzoic acid cardanol dye with polyurethane of soybean oil. The IPNs produced have been characterized by FTIR, TGA, DSC (Differential scanning calorimetry). Elemental analysis and WAXRD studies. Thermal stability of IPNs has been studied by both TGA and DSC which provides heat capacity and kinetic parameters (order of reaction and activation energy) by Freeman Anderson method of the sample.

Keywords: Cardanol based dye, thermal stability, crystallinity, activation energy, interpenetrating polymer network.

Abstract: Poor aqueous solubility of some chemical entities presents a major challenge to modern drug delivery. Self emulsifying drug delivery systems (SEDDS) have gained exposure for their ability to increase solubility and bioavailability of poorly soluble drugs. SEDDS are mixtures of oil, surfactant and co-surfactant which are emulsified in aqueous media under conditions of mild agitation and digestive motility that are encountered in the gastrointestinal (GI) tract. The aim of this study was to develop a novel formulation of SEDDs using simvastatin which is a poorly water soluble drug. The study was conducted by preparing SEDDS with moringa oleifera and beniseed oils, tween 80 (surfactant) and polyethylene glycol (co-surfactant). After screening of various vehicles (oil, surfactant.......

The yam and cocoyam flour were found to be a good sources of minerals; calcium 198.72 ± 0.021 and 135.40 ± 0.020 mg/100g respectively, magnesium 140.23± 0.052 and 69.20 ± 0.055 mg/100g respectively. All the flour sample are good sources of potassium of 453.36 ± 1.001, 272.10 ± 0.921, 219.00 ± 1.100 and 445.200 ± 2.150mg/100g respectively. Among the selected functional properties determined, all the flour samples have high dispersibility, Yam flour (92.6 ± 0.01), Cassava flour (78.35 ± 0.06), Cocoyam flour (45.7 ± 0.03) and Plantain flour (50.15 ± 0.01). Plantain flour has the highest bulk density of 0.77 ± 0.02 g/mg and highest solubility of 17.92 % with the lowest swelling power (g/g) 5.42 ± 0.03. The water absorption index of cassava flour of 74.15 5 %is very high compare with others that were less than 2 %.

Abstract: Dark pepper (Piper nigrum L.) has for quite some time been viewed as a spice added to numerous nourishments and it is additionally considered as a medicinal plant. The predominant compound got from ethanolic concentrate of P. nigrum, the piperine, was crystallized. Piperine, a noteworthy alkaloid in dark pepper is a standout amongst the most encouraging bioenhancers till date. Piperic acid was synthesized by alkaline hydrolysis of the cleaned piperine. A progression of piperine analogs were incorporated by the buildup of piperic acid with various substituted aniline (3a-3e). The synthesized compounds (4a– 4e) were assessed for their anticancer activity against human growth cell lines (HEPG............

Abstract: In traditional medicine most of the diseases have been treated by administration of plant or plant product. Neem (Azadirachta indica ) is the most useful traditional medicinal plant in India. Each part of the neem tree has some medicinal property. During the last five decades, apart from the chemistry of the neem compounds, considerable progress has been achieved regarding the biological activity and medicinal applications of neem. It is now considered as a valuable source of unique natural products for development of medicines against various diseases and also for the development of industrial products. This review gives a bird's eye view mainly on the biological activities of the neem seed and some of their compounds isolated from the neem seed oil, pharmacological actions of the neem extracts, clinical studies and plausible medicinal applications of neem seed along with their safety evaluation.

Abstract: The adverse effect of river Ramgnga on growth parameters of selected rabi crops viz Mustard (var-Pioneer 45546, Soyabean (var-JS 9566), Groundnut (var RG-559) and Linseed (var - Jawarhar - 23). found to be increased. The physico-chemical parameters such as pH, total hardness, BOD, COD, DO etc. of the river Ramganga found to be increased the man causes of water pollution in the river are the disposal of human sewage, animal wastes, increasing pollution and disposal of brass industries effluent. In this manuscript chemical content and the effect of river Ramganga on growth contributory attributes like NAR, LAR, RGR and CGR in same rabi & kharif crops were studied in pot culture experiments, a mark decline in various growth parameter was observed. However Linseed performed was well as compared to other crops.
