Research ArticleOpen accessIn the abstractOvicide and Larvicide Activities of the Essential Oils Extracted from Polyalthia longifolia and Clausena anisata on Sitotroga cerealellaGuy Alain Alitonou, Jean Pierre Noudogbessi, Philippe Sessou et al.This work has objectives to study the chemical composition of volatile extracts obtained from leaves of Polyalthia longifolia and Clausena anisata and to evaluate their ovicide and larvicide effects by fumigation against Sitotroga cerealella, as alternative to the pesticides of synthesis. The analyses of the extracts by GC-MS showed that the essential oil of P. longifolia contains 57 compounds representing … …OnLine Journal of Biological Sciences, Vol. 17, Issue 3 · 19 Jul 2017 · 7,779 accessesView PDFCite
Research ArticleOpen accessIn the abstractTotal Phenolic Composition and Antioxidant Activity of Silver Nanoparticles using Aqueous Extract of Chilca Leaves (Baccharis latifolia)Fernanda Pilaquinga, Camila Granja, Eliza Jara et al.The importance of studying polyphenols as natural antioxidants has encouraged the search for new methods of rapid, simple analysis. The synthesis of silver Nanoparticles (Ag NPs) using plant extracts has been presented as an alternative to determine the presence of polyphenolic compounds. In this study, aqueous extract of chilca (Baccharis latifolia), an endemic plant species from South America known for … …American Journal of Applied Sciences, Vol. 18, Issue 1 · 16 Apr 2021 · 8,349 accessesView PDFCite
Research ArticleOpen accessIn the abstractOne Can Slow Down the Aging through AntioxidantsRaffaella Aversa, Relly Victoria V. Petrescu, Antonio Apicella, Florian Ion T. PetrescuFree radicals are natural nanoparticles which are doing their part well defined in the human cell, but then they must be annihilated or eliminated to not destroy the cell or another part of our body. It has been shown that residual free radicals in the body are responsible for the aging. The role to annihilate them is ful-filled by the … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 8 Dec 2016 · 10,076 accessesView PDFCite
Review ArticleOpen accessIn the abstractThe Status of Pollutants in the Three Gorges Reservoir Area, China and its Ecological Health AssessmentChun-Jiao Lu, Dan Luo, Muhammad Junaid et al.The Three Gorges Reservoir Area (TGRA) stretches along the Yangtze River from Jiangjin District, Chongqing to Yichang, Hubei in China. Since TGRA is the main source of drinking water and fresh fishery in China for millions of people, both researchers and the government have concerns for environmental pollution and ecological security in the TGRA. This review highlighted the status and … …American Journal of Environmental Sciences, Vol. 12, Issue 5 · 28 Sep 2016 · 7,932 accessesView PDFCite
Research ArticleOpen accessIn the abstractEssential Oil Chemical Composition of Myrtle Growing in Northeastern Algeria and Estimation of its Antibacterial EffectivenessBarhouchi Badra, Aouadi Saoudi, Abdi AkilaThe aim of this study is to determine the antibacterial effectiveness of leaves essential oil extracted from myrtle growing in Algeria. A cluster analysis of soil and water was effectuated for performing chemical and granulometric analyses. The essential oil was isolated from leaves by hydro distillation and analyzed by Gas Chromatography-Mass Spectrometry (GC/MS). The leaves yield reached a peak at … …American Journal of Biochemistry and Biotechnology, Vol. 12, Issue 2 · 5 Apr 2016 · 8,360 accessesView PDFCite
HypothesisOpen accessIn the abstractNew Opportunities for Fullerenes and for GrapheneClive DelmonteThis is a conjecture which defines a new class of electrically conducting polymer that chemically confines metals, ions or clusters within an electric potential constraining them to react in ways novel to chemistry. The polymers are planar on a planar surface and adhere as a П-bonded electron sheet to planar, electron-delocalized surfaces as in Fullerenes, graphene (both sides) and graphite. … …Current Research in Nanotechnology, Vol. 6, Issue 2 · 1 Jan 2016 · 13,965 accessesView PDFCite
Research ArticleOpen accessIn the abstractChemotaxonomy of Indonesian Citrus maxima based on Leaf Essential OilsRatna Susandarini, Rugayah, Lauretius Hartanto Nugroho, Siti SubandiyahPummelo (Citrus maxima) is one of true citrus species originated from South East Asian regions. Pummelo is known as having high morphological diversity, but lacking of comprehensive publications documenting chemical diversity. The objectives of this study were to reveal essential oil diversity and its implication on the chemotaxonomy of the species. Leaves from forty individual plants were collected from seven … …OnLine Journal of Biological Sciences, Vol. 16, Issue 1 · 29 Dec 2015 · 8,103 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpecific Features of the Accumulation and Distribution of Heavy Metals in Soils of the Floodplain and Deltaic Landscapes of the Don RiverTatiana M. Minkina, Dina G. Nevidomskaya, Yuriy A. Fedorov et al.The purpose of this work was to study specific features of the accumulation and distribution of the total content and mobile forms of Heavy Metals (HM) in soils of the estuarine ecosystems of the floodplain and deltaic landscapes of the Don River. The results allowed us to detect regional specific features in the formation of HM compounds in floodplain soils … …American Journal of Applied Sciences, Vol. 12, Issue 11 · 19 Nov 2015 · 6,593 accessesView PDFCite
EditorialOpen accessIn the abstractRe-Paving the Road Built by Chemistry: A Challenge to Biochemistry and BiotechnologyAlberto A. IglesiasBiochemistry’s birth can be placed at the end of the nineteenth century, when Eduard Buchner made a clever interpretation of experimental observations on the generation of gas bubbles after addition (the original purpose was preservation) of sucrose to a yeast crude extract (Lagerkvist, 2005). Intelligently, Buchner concluded that the disaccharide had been fermented by broken cells’ suspension to produce CO2, … …American Journal of Biochemistry and Biotechnology, Vol. 11, Issue 1 · 26 Jan 2015 · 7,468 accessesView PDFCite
