Three different phytoene desaturase genes, from Rhodobacter capsulatus, Erwinia uredovora, and Synechococcus PCC 7942, have been functionally complemented with a gene construct from E. uredovora which encodes all enzymes responsible for formation of 15-cis phytoene in Escherichia coli. As indicated by the contrasting reaction products detected in the pigmented E. coli cells after co-transformat...

A simple and accurate reversed phase high-performance liquid chromatography coupled with diode array detector (HPLC-DAD) method for simultaneously determining and quantifying the antioxidants carotenes, xanthophylls, and retinol in human plasma is presented in this paper. Compounds were extracted with hexane, a C30 column, and a mobile phase of methanol, methyl tert-butyl ether, and water were ...

Citrullus colocynthis (L.) (C. colocynthis), commonly known as Handal in Yemen and other Arabic countries, is a plant with wide range of pharmacological properties. These properties are attributed to secondary metabolites, phytochemicals, present the plant. In this study, seed C. were extracted using dichloromethane, resulting oil extract was screened identify active phytoconstituents gas chrom...

The aim of the research is to develop new bakery products with increased functional value by adding ingredients from biomass Spirulina platensis. High quality wheat flour (P1), oatmeal (P2) and whole (P3) sticks were formulated addition 3% S2 preparation based on spirulina, thus increasing bioavailability active components in microalgae. It was established that results an increase total polyphe...
