    Abstract: Niosomes are unilamellar or multilamellar vesicles capable of entrapping hydrophilic and hydrophobic solutes.  Niosomes are promising drug carriers as they possess greater stability. Niosomes is currently reported to increase drug stability, and increase the penetration of the adsorbed compound across the skin. Thus noisome could be incorporated in semisolid formulation. Quercetin niosomes were prepared by using Cholesterol, Span 80/ Span 85 as surfactants, chloroform, and diethyl ether using ether injection method. Formulation was then evaluated for particle size, drug content, entrapment efficiency, and in-vitro drug release studies. Niosomal Gel Prepared by Carbopol 934P and characterized as Drug Content, in-vitro Cumulative Drug Release and viscocity. Quercetin released from the Plain Gel to 68.64 in 8 hrs. The skin permeation increase of quercetin drug was recorded from vesicle Gel in comparison to plain gel and antioxidant activity performed by DPPH Method. The results showed that quercetin has considerable whitening and antioxidant capacities and Span80+85(1:2) Niosomes remarkably improved the solubility and photostability of quercetin. Furthermore, compared to quercetin solution, quercetin-niosomes had the advantages of sustained release and improved transdermal penetration. Niosomal Gel storage under refrigeration showed greater stability. The results suggested that Niosomes could better promote the transdermal delivery of quercetin, by their ability to control drug release.

    Abstract: Microspheres carrier system made from natural or synthetic polymers used in sustained release drug delivery system. The present study involves formulation and evaluation of floating microspheres of Curcumin for improving the drug bioavailability by prolongation gastric residence time. Curcumin, natural hypoglycemic agent is a lipophilic drug, absorbed poorly from the stomach, quickly eliminated and having short half-life so suitable to formulate floating drug delivery system for sustained release. Floating microspheres of curcumin were formulated by solvent evaporation technique using ethanol and dichloromethane (1:1) as organic solvent and incorporating various synthetic polymers as coating polymer, sustain release polymers and floating agent. The final formulation were evaluated various parameters such as compatibility studies, micrometric properties, In-vitro drug release and % buoyancy. FTIR studies showed that there were no interaction between drug and excipients. The surface morphology studies by SEM confirmed their spherical and smooth surface. The mean particles size were found to be 416-618µm, practical yield of microspheres was in the range of 60.21±0.052% - 80.87±0.043%, drug entrapment efficiency 47.4±0.065% - 77.9±0.036% and % buoyancy 62,24±0.161% - 88.63±0.413%. Result show that entraptmency increased as polymer (Eudragit RS100) conc. Increased. The drug release after 12 hrs. was 72.13% - 87.13% and it decrease as a polymer (HPMC, EC) concentration was decrease.

    Abstract: In today’s scenario, fungal and bacterial infections are one of the most challenging pestilential diseases for the health-care professional which is increasing with a very high rate in the growing population, especially among the immune compromised people.The present work involved the study to extract active principles of Moringa concanensis and perform antibacterial and antifungal activity for various extracts. The leaves were dried powdered unexpected using solvents petroleum ether, chloroform, ethanol and water. Chemical tests were performed to ascertain presence of various classes of phyto-constituents like alkaloids, glycosides, saponins, carbohydrates, proteins, amino acids tannins, flavonoids and phenolic substances. All four extracts showed the presence of various phytochemicals responsible for multiple pharmacological activities. The extracts were reconstituted using 1% aqueous solution of carboxy methyl cellulose and were tested for antibacterial and antifungal activity against six microorganisms, namely Bacillus subtilis, Enterobacter aerogenes, Bacillus cereus, Aspergillus Flavus, Aspergillus Niger and Helminthosporium, using well diffusion method. The results of the activity are promising with chloroform extract showing highest inhibitory activity against most of the organisms. All the extracts were able to demonstrate significant activity compared to control inhibition of microorganisms tested and hold key to discover lead molecules after further scientific investigation.
