Biosynthesis of Silver Nanoparticles using Leaf and Stem Extracts of Eclipta alba and their Medical Applications
Abstract: AbstractBiosynthesis of silver nanoparticles using plants has emerged as a simple and feasible alternative to more complex physical and chemical synthetic procedures. Nanoparticles synthesis through greener routes can be used in a safer mode for various human applications. In this work, we describe a cost effective and environment friendly technique for biosynthesis of silver nanoparticles from 1mM AgNO3 solution using leaf and stem extracts of Eclipta alba as reducing as …

Optimization of Red Pigment Yield from Monscus purpureus Solid State Fermentation (Isolation and Characterization of Monscus purpureus and Optimization of its Red Pigment Production)
Abstract: Natural pigments production is one of the important approaches recently for being natural and having therapeutic properties. Monscus purpureus was isolated from imported red yeast rice, characterized and propagated on local rice as solid state culture. Morphological characteristics which include colonies, ascosporous and conidial stage were used to identify the fungi besides its red pigment production. Red pigment was produced using 10% of seed culture of Monescus purpureus, incubated at …

Oxalate and Mineral Composition of Amoche [Arisaema Schimperianum Schott.] Influenced as Different Processing
Abstract: Oxalate content of amoche [Arisaema Shcimperianum S.] as influenced by different processing were determined by High Performance Liquid Chromatography. The mineral contents were also determined by Spectrophotometre. The different processing treatments were combinations of three levels of fresh, boiliing, drying and three levels of soaking in ginger, lemon and ethanol and neither heating nor boiling [control]. Different processing significantly [p<0.05] influenced the oxalate and mineral contents. The oxalate contents observed …

A Study on Characterization of AA-AMPS-Pb Composite by Spectroscopic and Thermal Methods
Abstract: Spectroscopic and thermal properties of Acrylamide-acrylamide 2- methyl propane sulphonic acid (AA-AMPS) copolymer have been investigated by spectrophotometric, Fourier transform infrared (FTIR), differential scanning calorimetry (DSC) and scanning electron microscope (SEM) techniques. The UV absorption studies indicate the presence of lead nano particles and FTIR results suggest that complexation has been taken place between reactive groups of copolymer and lead ion. Due to the presence of lead nano particles thermal …

Potentials of Carrot (Daucus carota) and Cocoyam (Colocasia esculenta) Peels as Suitable Mycological Culture Media
Abstract: Potentials of carrot (Daucus carota) and cocoyam (Colocasia esculenta) peels as suitable mycological culture media was investigated in the present study. The method employed for proximate composition involved the spectrophotometric, oven drying and furnace drying method. Standard methods of isolation, characterization, growth rate and antifungal activities were employed. The result revealed that both carrot and cocoyam peels were rich in carbohydrates, protein, ash, moisture and crude fiber contents.The growth of …
