characterization

Ni (II) and Mn (II) metal complexes of Schiff base derived from ethylenediamine, succinic acid and formaldehyde. The newly synthesized Schiff base complexes were characterized by elemental analysis, Melting point, conductivity, IR and UV-VIS spectral methods. The complexes have been tested using for the catalytic oxidation of benzylacohol using ecofriendly molecular oxygen as catalyst. The results show that Nickel complex shows highest yield oxidation product as compared to Manganese at 35°C temperature, 90mg catalyst amount and 25 min. time.

Co(II), Fe (III) and Cu (II) metal complexes of Schiff base derived from ethylenediamine, succinic acid and formaldehyde. The newly synthesized Schiff base complexes were characterized by elemental analysis, Melting point, conductivity, IR and UV-VIS spectral methods. The complexes have been tested for their antimicrobial activity against bacteria and fungi. The anti- microbial activity was determined in Mueller Hinton media (M H Media).

Natural products from medicinal plants, either as pure compounds or as standardized extracts, provide unlimited opportunities for new drug leads. Due to an increasing demand for seeking therapeutic drugs from natural products there is a need to develop analytical methodologies for different purposes which include the extraction, isolation and characterization of active ingredients in botanicals and herbal preparations. Various analytical methods available for the isolation, characterization and quantification of active ingredients from plant extracts which include various spectrometric and chromatographic methods along with some hyphenated techniques are discussed. The present review helps to design a method for the isolation, characterization and quantitative determination of major constituents from plants.

Unique properties of Nanofibers have attracted for the designing of controlled drug delivery systems due to high surface area to volume ratio, porosity so only we can applied in advance application such as Biodegradable and controlled drug delivery systems. The benefits of the fibrous carriers are site specific delivery of drugs to the body. Nanofibers are an exciting new class of material produced using an innovative manufacturing process technology. These fibers are produced from a variety of polymers in geometrical shapes ranging from Nonwoven web, yarn, and bulk structures. The Synthetic polymer Nanofibers are made from Nylon, Acrylic, Polycarbonate, Polysulfones, and Fluro polymers among other polymers. The biological polymer nanofibers are made from materials such as Polycaprolactum, Chitosan, Polylactic acid, and Copolymer of Polylactic/glycolic acid among other biopolymers. At present, there are three techniques available for the synthesis of Nanofibers: Electro spinning, self-assembly, and phase separation, out of these Electro spinning is the most widely used technique. Mostly , the bioactive molecules like anti-cancer drugs, enzymes. Cytokines, and polysaccharides can be entrapped within the interior or physically immobilized on the surfaces of nanofiber for controlled drug delivery. The advanced approach for creating Nanofibers made of proteins developed, greatly improve drug delivery methods for the treatment of cancers, heart, and Alzheimer’s diseases, as well as aid in the regeneration of human tissue, bone and cartilage. This review paper reports on fabrication of nanofibers and its characteristics and high tech application in drug delivery, tissue engineering and filter medium.
