Research ArticleOpen accessEvery word in the titleWays of Increasing Seed Germination of Sweet Clover and Methods of Reducing the Amount of Coumarin in the Leaf-Stem MassMarden Ersainovich Baidalin, Igilik Imangalievich Zhumagulov, Ermek Ualikhanovich Sagalbekov, Ualikhan Molgazhdarovich SagalbekovThe article presents the results of laboratory and field experiments on studying the influence of ways of presowing seed treatment and methods of reducing the amount of coumarin on yield and forage quality of sweet clover in the conditions of Northern Kazakhstan. The aim of the research is to study and to prove the effective way of presowing treatment of … …OnLine Journal of Biological Sciences, Vol. 17, Issue 2 · 17 Jun 2017 · 7,241 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSynthesis and Biological Evaluation of 6-Hydroxy-4-Methyl-5,7-(Bis-p-ChlorophenylAzo) CoumarinDalal M. Ibrahim, Juliana Jumal, Farah Wahida Harun6-hydroxy-4-methyl-5,7-(bis-p-chlorophenylazo)coumarinhas been synthesized and characterizedby CHN elemental analysis, FTIR, 1H-NMR-spectroscopy andmass-spectral data. Cytotoxic screening by MTT assay was carried out on the compoundagainst breast cancer cells. The overall results from preliminary screeningprogram revealed that the cell proliferation was highly inhibited by 6-hydroxy-4-methyl-5,7-(bis-p-chlorophenylazo)coumarin with the value of 2.81%, at concentration of 30 µg mL-1 comparedwith the untreated control cells and also … …American Journal of Applied Sciences, Vol. 13, Issue 1 · 21 Dec 2015 · 7,670 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleANTICONVULSANT AND NEUROTOXICITY EVALUATION OF SOME NEWLY SYNTHESIZED THIAZOLYL COUMARIN DERIVATIVESM. Faiz Arshad, Nadeem Siddiqui, Ahmed Elkerdasy et al.The present series of compounds were synthesized with the aim to develop newer anticonvulsant agents that are comparatively more efficacious and safer than the currently used anticonvulsant agents. Various thiazolyl coumarins were synthesized by the reaction of 3-(bromoacetyl)-2H-chromen-2-one with different substituted aryl thiourea. The structures of the synthesized compounds were confirmed by spectral data and elemental analyses. Compounds were tested … …American Journal of Pharmacology and Toxicology, Vol. 9, Issue 2 · 26 Mar 2014 · 7,676 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAntimicrobial Properties of Newly Synthesized Derivatives of CoumarineS. Govori, S. Spahiu, V. Kalaj et al.Problem statement: Coumarins are well known for their biological activity. On the basis of that we have synthesized some new derivatives of coumarine and investigated their antimicrobial properties. Approach: 4-Heteroaryl-coumarin-3-carbaldehydes 4(a-d) are synthesized by condensation of 4-chloro-coumarin-3-carbaldehydes 2 and corresponding heterorylamines 3(a-d) under reflux reaction conditions. Antimicrobial properties of new coumarins 4(a-d) are investigated and results are submitted for their … …American Journal of Biochemistry and Biotechnology, Vol. 6, Issue 4 · 31 Dec 2010 · 9,673 accessesView PDFCite
Research ArticleOpen accessIn the abstractEfficiency of Carica papaya L. Seeds in Anticoccidial Control for Cockerel of Lohmann Brown StrainKomlan Mawouli Wampah, Kosi Mawuéna Novidzro, Namponi Dianam, Abalo Essosimna KuloTo combat avian coccidiosis, chemical products are widely used in poultry farming. However, chemotherapy has inconveniences due to the bioresistance of Coccidia and the presence of undesirable residues in consumer products. The aim of this study is to investigate the toxicity of papaya seeds as a bio-insecticide against Coccidia in Lohmann brown chickens in order to improve their zootechnical parameters. … …American Journal of Animal and Veterinary Sciences, Vol. 19, Issue 1 · 27 Jan 2024 · 6,659 accessesView PDFCite
Research ArticleOpen accessIn the abstractAutomatic Identification of Molecules in a Thin-Film Extract Combined with LaserTheodore Guié Toa Bi, Sié Ouattara, Alain ClementThis paper presents the automation of the thin-layer chromatography technique whose separation and identification of molecules present in a mixture are currently done manually and laboriously. We have therefore found an interest in automating this technique. In this part, the method implemented comprises 2 steps. First we proceeded to the segmentation of the spots obtained on the chromatographic plate. We … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 4 · 14 Nov 2018 · 7,089 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparative Studies on Proximate Composition and Phytochemical Screening of Mango, Key lime, African star apple and African pear Seeds as Possible Coagulant Aids for Water TreatmentAnimetu Seghosime, Johannes Akpabla Mawuli Awudza, Richard Buamah, Sampson Oduro KwartengMany fruits including mango (Mangifera indica), key lime (Citrus aurantiifolia), African star apple (Chrysophyllum albidum) and African or bush pear (Dacryodes edulis) are nutritionally valuable as human food, however after consumption of the fruits, their seeds are discarded as wastes since they are of no commercial value and this results in disposal problems. Hence assessment of the constituents of such … …American Journal of Environmental Sciences, Vol. 13, Issue 4 · 12 Aug 2017 · 9,950 accessesView PDFCite
