Quercetin from n-butanol Soluble Fraction of Crude Ethanol Leaf Extract of Cadaba Farinosa Forssk
Abstract The plant Cadaba farinosa Forssk (Capparaceae) is distributed throughout the world in mostly tropical and sub-tropical regions. It is used in treatment of pains, dysentery, rheumatism, cough, fever, as antidote and neurological disorders. Phytochemical screening of the leaf revealed the presence of alkaloids, anthraquinones, carbohydrates, cardiac glycosides, flavonoids, glycosides, saponins and tannins. Silica gel […]
Optimization of Graham Glass Condensing Models for Extraction of Natural dye and Rate of Solvent Recovery Process
Abstract This study was undertaken with a view to investigate the effects of the number of bulbs on performance of A Graham outer jacket glass condensers. AutoCAD was used to design Graham condensers varying the number of bulbs from one to ten (1-10) on the outer jacket; while maintaining the following specifications, outer bulbs size […]
Inhibition of Oilfield Scales using Plant Materials: A Peep into Green Future
Abstract Oilfield scales have been effectively managed using scale inhibitors derived from inorganic and organic polyphosphates, carboxylic acid and carbohydrate based polymers, and ethylene diamine tetracetic acid (EDTA) based compounds. Many of these compounds are toxic and very expensive. Providentially, some of the active functionalities present in these compounds could be obtained from isolates or […]
New Studying for One-pot Multicomponent Reactions to Prepare Novel Furochromone Compounds with Antitumor Activity
Abstract The refluxing of furochromone carboxaldehyde (1) and dimethyl acetylene dicarboxylate with amine derivatives namely m-nitroanilline, p-methylanilline, o-aminophenol, o-anisidine and p-anisidine to give compounds (2a-e). While the reaction of mixture of furochromone carboxaldehyde (1) with dimethyl acetylendicarboxylate in the presence of cyclohexyl isocyanide to afford compound (3). The reaction mixture of furochromone carboxaldehyde (1), cyclohexyl […]
Synthesis of novel [4, 9-dimethoxy-5H-furo [3, 2-g] chromen-5-one] derivatives with antiproliferative potency towards breast and hepatic cancer cell lines
Abstract Chromen derivative (2) was obtained by the reaction of [cyclohexyl isocyanide, furochromone carbaldehyde (1), cyclohexane-1, 3-dione]. Also, reaction of compound (2) in the presence of semicarbazide hydrochloride to proceed the compound (3) which react with selenium dioxide to form compounds (4). In one-step, the condensation of cyclohexyl isocyanide, furochromone carbaldehyde (1) and pentane-2-dionein pipredine […]
GC-MS Analysis of Induced Metabolites in Cell Suspensions of Cotton (Gossypium hirsutum L.) under Methyl Jasmonate and Ethephon Treatment
Abstract The study aims to determine the phytochemical constituents present in the cell suspensions of cotton elicited by MeJA and ethephon. Elicitors were added alone or in combination. The freeze-dried cells were soaked with 10 mL of methanol 96% and purified through a mini-column of C18. After concentration of filtrate, the dry extract was dissolved […]
Biochemical Studies on Red Algae Gelidium sp. Grown in Egypt
Abstract The present work aims to study the potentialities of macroalgae Gelidium sp. collect from Mediterranean Sea as new source of bioactive substance. Thus, the chemical and biochemical components for these algae were isolated and characterized which includes antioxidant activity. The proximate chemical composition of Gelidium sp. were protein content (13.23 ± 1.06% DW), crude […]
Analysis of Postprandial Hyper-triglyceridemia in Type 2 Diabetes Mellitus (T2DM) Patients with Presence of Micro-albuminuria
Abstract It is postulated that in patients with Type 2 Diabetes Mellitus (T2DM) and presence of microalbuminuria (MA) shows higher postprandial triglyceride than those without MA. The present study therefore analyze the potential association and to elaborate the degree of dependence of T2DM with MA condition on onset of high postprandial (PP) triglyceridemia. A total […]
