The proportion of geometrical hydroperoxide isomers generated by aerobic oxidation of methyl linoleate (18:2 Me) in either aqueous emulsion consisting of Tris-HCl buffer (pH 7.4) or in a homogeneous dichloromethane solution was determined to understand the mechanism of lipid oxidation in different
We showed previously that exposure of mice to atmospheric nitrogen dioxide (NO2) leads to the formation of an ether-extractable nitrosating agent (NSA) in the skin, which produced N-nitrosomorpholine (NMOR) from morpholine in vitro but not in vivo (under our conditions). We now report that NO2
Vector control strategies play significant role in reducing the transmission of malaria, dengue and other vector-borne diseases. The control of vector population using synthetic insecticides has resulted in development of insecticide resistance and negative effects on humans and Ginger (Zingiber officinale Roscoe) shows an antioxidant activity, and we have been engaging to determine the structures of more than 50 antioxidants isolated from the rhizomes of ginger. The isolated antioxidants are divided into two groups; gingerol related compounds and diarylheptanoids. In this
Light petroleum, dichloromethane and methanolic extracts of Linum usitatissimum were investigated using GC/MS. The main components of three sequential extracts were methyl linolenate (11.9-33.9%) and methyl linoleate (3.4-9.1%). Components possessing antimicrobial activity against acne causing
