UV irradiation is one of the main causes of what is known as photoaging characterized by loss of skin elasticity and the appearance of wrinkles. In this study, the anti-wrinkle activity of grape seed extract (GSE) and Pomegranate seed extract (PSE) was studied through evaluation of their in-vitro antioxidant, anti-tyrosinase and in-vivo anti-wrinkle activity in UVB-irradiated mice through topical application of PSE and GSE at 50 mg/kg/twice a week for 15 weeks. The total phenolic content of PSE and GSE was 2.1375 and 5.9625 mg GAE/g extract, respectively. PSE and GSE also showed DPPH scavenging activity with IC50 of 37.9 and 29.9 µg/mL, respectively. PSE and GSE showed anti-tyrosinase activity with IC50 of 115 and 107.75 μg /mL, respectively, while that of Kojic acid is 17.45 μg /mL. In UVB-irradiated mice, the increased expression of metaloproteinase (MMP-2) was significantly inhibited by PSE and GSE where their activities exceeded that of the standard turmeric extract (TME). The topical application of PSE, GSE, and TME of the UVB radiated groups prevented...

Vascular dementia (VaD), a diverse group of brain disorders with cognitive decline is attributable to cerebrovascular pathologies. Recent studies have shown that mitochondrial dysfunctions and oxidative stress are involved in cognitive decline. The aim of the present study was designed to evaluate the effects of Curcumin loaded solid lipid nanoparticles (Cur-SLNP) in vascular dementia (VaD) against homocystiene (HCY) induced toxicity by behavioral and biochemical assessment in different regions of the brain. The sign of VaD, i.e., learning and memory levels, were evaluated with a different behavioral assessment like plus-maze test. Neurobehavioral analyses revealed that the Cur-SLNP administration successfully ameliorated cognitive decline observed in HCY rats. Compared to HCY administration, Cur-SLNP 10 mg/kg and 25 mg/kg administration showed ameliorative effect in behavioral and biochemical assessment induced by HCY. We found that lipid peroxidation levels decreased significantly in striatum (p<0.01), cortex (p<0.001), and hippocampus (p<0.001) after oral administration of Cur-SLNP with HCY animals. Hence, the present findings suggest that the neuroprotective role of Cur-SLNP against HCY induced toxicity could be a...

Aegle marmelos L. (Bael), is a commonly occurring herb which has biomedical potency to treat many types of diseases such as diarrhea, hepatoprotective, epilepsy, stomachalgia, digestion related problems etc. The different parts of Aegle marmelos (L.) were collected, dried and coarsely powdered. The present study deals with the physio-chemical constants standardization parameters such as pH, solubility including water and methanolic extraction, total ash, acid insoluble ash, water soluble ash, extractive values, dry and wet particle size, foaming index, swelling index, foreign matters, loss of drying (LOD) and acidity were observed. Fluorescence analysis was performed for study of behavioral characters of the pulp without seed, pericarp, leaf and seed powder treated with chemical reagents. Extractive values of powder with solvents such as water and methanol were determined. Macroscopical characters help in identifying the fruit, pulp, pericarp, leaf and seed. Anatomical observations showed the presence of palisade cell, trichomes, mesophyll cell, collenchymas, xylem, phloem, pith, upper epidermal cells and lower epidermal cells with stomata. Preliminary qualitative phytochemical screening reported the presence...

In the present study two subclasses of coumarin derivatives were selected 14 coumarin sulphonamides and 14 coumarin schiff bases i.e., totally 28 compounds from our earlier research work. A comparative study for two subclasses of coumarins by using various CADD (online and offline) softwares. Computational calculations and predictions of important molecular properties suggest that among the two sub classes of coumarin derivatives, coumarin Schiff bases could be further improved to provide biologically active...

The recent work is based on the extraction and purification of natural gum from the bark of plant Terminalia elliptica (local name – Saaj) and the use of this gum to prepare pulsatile Drug Delivery System of Atenolol for the chronotherapy of cardiovascular diseases. Three formulations CF1, CF2, CF3 of core tablets were prepared by direct compression technique by varying concentrations of crospovidone and evaluated. Formulation CF3 showed the highest 98.71% of drug release after 30 min was selected for press coating. Press coated tablets of Formulation F1 to F5 were prepared by direct compression technique using varying combinations of Saaj gum and Ethylcellulose in the ratio of 1:0, 3:1, 1:1, 1:3 and 0:1 respectively by taking CF3 as core in all. The extracted gum, powder blends, core tablets, and press coated tablets all were evaluated for their physicochemical properties. From the dissolution study of formulation F1 To F5 it was found that F2 having 3:1 combination of Saaj gum and EC shows a significant lag time of around...
