Objective: To assess the anti-oxidant activity of different seaweed extract. Methods: Different seaweeds as Sargassum wightii, Turbinaria ornata, Gracilaria corticata and Gelidiella acerosa were collected from Mandapam, Ramanathapuram District, Tamil Nadu, India and assessed for their suitability as anti-oxidant compounds. Seaweeds were cleaned from epiphytes, washed, dried in shade and powdered. Algae extractions were performed using different solvents such as methanol, ethanol and hexane. Anti-oxidant potential of marine algal polyphenol from methanol, Ethanol and Hexane extract(s) of seaweed were determined using different method as DPPH radical scavenging assay, Ferric reducing anti-oxidant property (FRAP), Ferrous Ion Chelating Activity (FICA), Reducing power, Total Anti-oxidant Capacity (TAC). The total phenolic content from different seaweeds considered for its anti-oxidant activity. Results: The DPPH radical scavenging activity in methanol extract of brown seaweed Turbinaria ornata (83.8%) is most noteworthy. In Gracilaria corticata it was 79.07 % in ethanol extract. In Sargassum wightii brown seaweed, high activity in methanol and ethanol extracts (75.51% and 70.16%) respectively were observed. The DPPH activity in ethanol extract of...

A simple, reliable, accurate and precise method was developed for the simultaneous estimation of Fexofenadine and Montelukast in pharmaceutical dosage form. The chromatogram was run through Standard HSS C18 (2.1 × 100 mm, 1.8 µm). Mobile phase employed was 0.1% OPA Buffer and Acetonitrile taken in the ratio of 65:35 was pumped through column at a flow rate of 0.2 ml/min. The temperature was maintained at 30 °C. The optimized wavelength selected was 269 nm. The retention time of Montelukast and Fexofenadine was found to be 0.921 and 1.101 min. The Percent RSD of the Montelukast and Fexofenadine were and found to be 0.7% and 0.4% respectively. The Percent recovery was obtained as 99.22% and 99.67% for Montelukast and Fexofenadine respectively. The LOD and LOQ values obtained from regression equations of Montelukast and Fexofenadine were 0.06, 0.18 and 0.80, 2.44 respectively. Regression equation of Montelukast was y = 6333.8x + 755.96 and y = 4038.3x + 8964.8 of Fexofenadine. The decrease in the retention and run times in this...

The objective behind this study is to investigate the affinity between a carboxylic model drug telmisartan and kaolin. Telmisartan was comilled in solid state with kaolin in different weight ratios and characterized by Fourier transform infrared spectroscopy, Differential scanning calorimetry, X-ray powder diffractometry, scanning electron microscopy to examine the extent of transformation from crystalline to amorphous state. XRD and SEM studies revealed complete amorphization of telmisartan on comilling with kaolin for 1 h at 1:2 ratio. FTIR study showed that on milling with kaolin, the free acid carbonyl peak of telmisartan at 1692.14 cm-1 was disappeared, and a new carboxylate peak at 1578.72 cm-1 appeared. This disappearance of acid carbonyl peak and appearance of new carboxylate peak indicating an acid-base reaction between the carboxylic acid of telmisartan and kaolin. DSC study stated that in the milled samples, the melting endotherm of telmisartan was gradually shifted to lower temperature, and the intensity, as well as sharpness of the endotherm, was decreased. In-vitro study showed greater dissolution of telmisartan from telmisartan-kaolin...

Areca catechu L. (Arecaceae) is a species of palm mainly grown in Asian countries for seed crop. Areca nut leaves are commonly used in traditional systems of medicine against various ailments. There is a need for identifying native natural plant sources to acquire their recognized medicinal properties, which may widen them to use as new therapeutics for various diseases. Phytochemical investigation of the leaves of Areca catechu L. yielded a alkaloid- Arecoline, from the chloroform extract; a flavonoid- Apigenin, from the methanol extract and a steroid- Stigmasterol, from petroleum ether extract. In-vitro methods were used to evaluate the pharmacological activity of the leaves of Areca catechu L. Anti-inflammatory activity of the leaves of Areca catechu was estimated by using standard methods like protein denaturation method using bovine serum albumin fraction and egg albumin and by HRBC membrane stabilization method. The result suggests that the leaves possess good antioxidant as well as anti-inflammatory...

Purpose of the study: To assess Structural and functional abnormalities associated with High fructose diet-induced Metabolic syndrome in wistar albino rats. Materials and Methods: Metabolic syndrome is induced in adult male Wistar albino rats by feeding a combination of High Fructose Diet (55%) and Fructose enriched water (15%) for 75 days and kept as group 2 or HFrD Group. Normal male Wistar albino rats were kept as Normal control. During the entire course of study, weekly weight gain was monitored once a week in both groups. Biochemical investigations such as lipid profile, liver function test, and renal function test was carried out using standard methods. Routine histological studies were done to analyze the microstructural changes. The obtained data were statistically analyzed by students‘t’ tests and the values were considered statistically significant at p<0.05. Results: Chronic administration of a High fructose diet (HFrD) resulted in obesity, abnormal hepatic and renal functions in wistar rats. The gross and microstructural changes were minimal in the pancreas and heart, whereas significant damages were...
