This study reports the isolation and antioxidant activity of non-polar terpenes extracted from the leaves of Bougainvillea glabra choicy. To characterize the phytochemical constituents of Bougainvillea glabra leaves using the GC-MS method. The 95% ethanol extract was filtered, distilled, and concentrated to obtain the solid greenish residue. The residue was further fractioned by n-hexane, chloroform, ethyl acetate, acetone, ethanol, and methanol. The GC-MS analysis of Chloroform extract of Bougainvillea glabra leaves revealed the presence of thirteen compounds that could contribute to the medicinal quality of the plant. The first compound identified with less retention time (9.50 min) was 1-(1-methyl-decyl)-decahydro-napthalene. The isolation of organic compounds was done using column and thin layer chromatographic techniques. Compound characterization using various spectroscopic techniques identified the final isolated compound as 1-(1-methyl-decyl)-decahydronapthalene. Antioxidant activity was evaluated by the DPPH method. The method of isolation is simple, cost-effective, and...

The aim of the present work is to formulate and characterize Econazole nitrate (EN) loaded transfersomal gel for antifungal activity. EN is a broad-spectrum imidazole antifungal agent that belongs to BCS Class II. Due to poor solubility, EN is incompletely absorbed after oral administration and bioavailability vary among individuals. Topical treatment of fungal infections is usually preferred, but the barrier is to cross stratum corneum, so formulating the drug in Transfersomes (TFs) solved this problem. TFs are a highly adaptable, stress-responsive, complex aggregate, and self-regulating membrane. EN loaded transfersomes were prepared by a thin-film hydration method. The EN-loaded transfersomes were optimized by the three factors and two levels Box-Behnken design using Design-Expert software (version 12). Independent formulation variables such as concentrations of phospholipid and two edge activators were evaluated. The prepared TFs were evaluated with respect to particle size, % entrapment efficiency, and % drug release. The prepared EN loaded TFs particle size ranging from 0.28 to 0.71 µm, entrapment efficiency in between 31.5 to 75%, and drug release...

RP-HPLC method has been developed for separation and quantification of Metoprolol succinate, Telmisartan, and Clinidipine using Phenomenex Luna C18 column (150 mm × 4.6 mm, 5 µm) as a stationary phase with security guard cartridge C18 (4 × 3 mm) and acetonitrile: methanol: phosphate buffer pH 7.5 (45:30:25) as a mobile phase by isocratic elution at the flow rate of 1.0 ml/min. The detection was carried out at 229 nm. The drugs are eluted at retention times 2.0, 2.8, and 6.8min for telmisartan, metoprolol succinate, and clinidipine, respectively. The method is linear in the range of 10-80 μg / ml, 6.25-50 μg / ml, and 2.5-20 μg / ml with regression coefficients 0.997, 0.995, and 0.999 respectively for telmisartan, metoprolol succinate, and clinidipine. The method is precise within the acceptable limits (% RSD- 1.22). The proposed method showed linearity, accuracy, precision, specificity, robustness, LOD, LOQ, and system suitability results within the acceptance criteria of ICH. The method can be applied for the routine analysis of pharmaceutical...

Tinospora cordifolia is one of the best medicinal plants holds most prominent place in Ayurveda Rasayana herbs and it also known as “rejuvenate herbs” because of its medicinal properties. It has been found to exhibit anti-microbial properties, its anti-microbial feature found in root, stem, and leaf extracts on pathogenic micro-organisms. Green synthesis of AgNPs can potentially eliminate chemical agents’ problems that may have adverse effects, thus making nanoparticles more compatible with the eco-friendly approach. The present study focuses on the green synthesize of silver nanoparticle, which was conducted by Tinospora cordifolia leaf extract. Characterization of silver nanoparticle was performed by Scanning Electron Microscopy. Silver nanoparticles exhibit strong anti-microbial effect against gram-positive and gram-negative bacteria such as Escherichia coli, Pseudomonas syringae, Staphylococcus aureus and Enterococcus faecalis. Both methanolic and ethanolic extract showed good antimicrobial activity against all the bacteria whereas methanolic extract had wide range of anti-microbial activity than ethanolic...

Department of Botany, Avinashilingam Institute for Home Science and Higher Education for Women, Coimbatore, Tamil Nadu, conducted a pot culture experiment for analyzing the effect of bio-composted groundnut shell and vegetable waste on the growth impact of Pigeon pea (Cajanus cajan (L.) Mill sp. Organic wastes and by-products are renewable forms of resources generated all over the world. The present work explores the potential application of eco-friendly compost from groundnut shell and vegetable wastes. The study mainly deals with the physicochemical properties of raw and composted vegetables and groundnut shell Waste, pH and Electric conductivity, Lignin, Total Nitrogen (N), Total Phosphorous (P), Total Potassium (K), and C: N ratio. Composting was carried out with the help of Trichoderma asperelloides, Pleurotus florida, and Eudrilus eugeniae. The experiments consist of four treatments viz., C control, T1- compost 1 (Vermi-composted groundnut shell and vegetable waste (25g)) T2- compost 2 (Vermi-composted groundnut shell and vegetable waste (50g), T3-compost 3 (Vermi-composted groundnut shell and vegetable waste (75g). Chlorophyll, protein, and carbohydrate content were analyzed...
