Aspergillus oryzae was used to enhance the mobilization of antioxidants of soybean matrix along with garlic as a co-substrate by modulating polyphenolic substances during solid-state fermentation. Mobilized polyphenols were used as a green tool for synthesis and stabilization of gold nanoparticles (AuNPs). The radiation-induced AuNPs synthesis is a simple, clean and inexpensive process which in...

Silicone surfactants are becoming increasingly important in the pharmaceutical and cosmetic industry, because of their versatility, low cost, and technological advantages. The present study was designed to measure the critical micellar concentration of three non-ionic silicone surfactants, one water-soluble and two lipid-soluble. We measured surface tension with a technique based on drop geomet...

Conventional matrix characterization by visible spectrophotometry technique required sample destruction and limited to drug content assay. This study investigated the capacity of visible spectrophotometry technique to characterize both drug content and molecular characteristics of solid nifedipine-hydroxypropylmethylcellulose films stored at 25 and 50 % relative humidities in their intact form....

This study aimed to analyze the chemical profile and evaluate biological activities of aqueous extract H. Scoparia, an endemic plant found in Southeastern Algeria. The was subjected phytochemical screening, RP-HPLC, FT-IR analysis. anti-inflammatory activity examined using protein denaturation method, photoprotective evaluated UV-Visible spectrophotometry. antioxidant assessed ABTS, DPPH, FRAP ...

Abstract Synthesis of silver nanoparticles was successfully synthesized by a chemical reduction method using nitrate (AgNO 3 ) as precursor and sodium borohydride (NaBH 4 reducing agent. The optical properties were studied based on their surface plasmon resonance (SPR) phenomenon UV-Visible spectrophotometry. absorbance spectra colloidal show the peak at wavelength range 380 nm to 450 nm. Collo...

Domestic water is abstracted from its sources in raw form with a high content of dissolved and suspended material. Polydiallyldimethylammonium chloride (polyDADMAC) is a cationic polyelectrolyte used in the initial water clarification process. However, its residues in treated water pose a health risk as they react with chlorine to produce a carcinogenic compound. There is a need to determine th...

Accepted: May 25, 2011; Published: August 30, 2011 Abstract The adsorption and transformation of K2Cr2O7 at natural hermit crab shell powder was studied by UV-visible spectrophotometry. K2Cr2O7 is adsorbed at natural hermit crab shell powder, and follows the Freundlich adsorption model with the adsorption constant of KF=888.8 and adsorption free energy change of 16.83 kJ.mol . The adsorbed K2Cr...

Thiocolchicoside is a centrally acting muscle relaxant and used in combination with many NSAIDs for the treatment of various musculoskeletal disorders. As it is less sedative than other centrally acting muscle relaxants hence frequently prescribed for low back pain (LBP), orthopedic, traumatic and rheumatologic disorders. It is available in market in single component and as multicomponent formu...
