The main monomer of tomato cuticle, 10,16-dihydroxyhexadecanoic acid (or 10,16-dihydroxypalmitic acid; 10,16-DHPA), was isolated and used to efficiently synthesize two different monomers (16-hydroxy-10-oxo-hexadecanoic and 7-oxohexa-decanedioic acids) in addition to a dimer and linear and branched trimers. These compounds were fully characterized using NMR and MS techniques and could be used as...

Mosquitoes are the carriers of severe and well-known illnesses such as malaria, arboviral encephalitis, dengue, chikungunya and yellow fever, which cause significant morbidity and mortality in humans and domestic animals around the world. Entomopathogenic fungal metabolites act as a mosquito control agent and are potential alternatives to chemical control because they can be innovative and more...

Hofmann and Lucas (1) discovered a saturated cyclopropane compound in Lactobadlus arabinosus which they termed lactobacillic acid. Lactobacillic acid was found to be &s-11,12methylene octadecanoic acid (2). A survey by Hofmann et al. disclosed that lactobacillic acid is present in several lactic acid bacteria (3) but absent in a group C streptococcus (4). Lactobacillic acid was also found to be...

BACKGROUND Albizia adianthifolia is used traditionally in Cameroon to treat several ailments, including infectious and associated diseases. This work was therefore designed to investigate the antioxidant and antimicrobial activities of ethyl acetate extract, fractions and compounds isolated from the stem bark of this plant. METHODS The plant extract was prepared by maceration in ethyl acetate...

Human skin fatty acids are a potent aspect of our innate defenses, giving surface protection against potentially invasive organisms. They provide an important parameter in determining the ecology of the skin microflora, and alterations can lead to increased colonization by pathogens such as Staphylococcus aureus. Harnessing skin fatty acids may also give a new avenue of exploration in the gener...

The search for novel drugs from higher plants led to the analysis of a novel plant source Rhynchosia capitata for its phytoconstituents. GC/MS study confirm the presence of oleic acid, octadecanoic acid, phytol, hexadecanoic acid, E-11-hexadecenoic acid, Z,Z,Z-4,6,9-nonadecatriene, tetradecanoic acid, 5-azulenemethanol and1-butanol. A highly sensitive reverse phase high performance liquid chrom...

The hexane extract of the flowers of Rheum ribes L. which was collected from north-western Iran,was obtained by Soxhlet apparatus and the essential oil composition was obtained by hydro distillationand analyzed by using GC-GC/MS. The extract from the flowers was characterized by a high amountof unsaturated fatty acids (UFA) (66.0%) and some of long chain hydrocarbon compounds. The maincomponent...

The efficiency of treating citric acid effluent by green algae Chlorella was investigated. With the highest growth rate, Chlorella vulgaris C9-JN2010 that could efficiently remove nutrients in the citric acid effluent was selected for scale-up batch experiments under the optimal conditions, where its maximum biomass was 1.04 g l(-1) and removal efficiencies of nutrients (nitrogen, phosphorus, t...
