This study was designed in order to correlate the flavonoid and lipoidal matters content of Spinach roots and flowers to their hypolipidemic potential. The total flavonoid content was measured via complexation with aluminum chloride while determination of fatty acids methyl esters and unsaponifiable matters contents in both organs was performed using GC/MS. In an in vitro study, the crude etha...

The total synthesis of two natural phenolglycosides of the family Salicaceae, namely: populoside and 2-(β-d-glucopyranosyloxy)-5-hydroxy benzyl (3-methoxy-4-hydroxy) cinnamoate and nine not found yet in plants acyl derivatives of phenoglycosides: 2-(β-d-glucopyranosyloxy)-benzylcinnamoate, 2-(β-d-glucopyranosyloxy)-benzyl (4-hydroxy) benzoate, 2-(β-d-glucopyranosyloxy)-benzyl (3-methoxy-4-hydro...

Objective(s): This study was designed to investigate various gastrointestinal effects of Manilkara zapota (Sapodilla), exploring its anti-diarrheal, anti-secretary, anti-spasmodic, anti-ulcer and anti-motility potential.Materials and Methods: Antidiarrheal and anti-secretary activities were investigated using castor oil induced diarrhea ...

The interactions between plants and pollinators are complex. Flower volatiles as special olfactory cues could influence the foraging choices of pollinators. Here, we conducted bioassays to evaluate role flower on attraction honey bees (native Apis cerana exotic mellifera) pears Pyrus bretschneideri communis). Chemical electrophysiological approaches were used determine antennal responses from p...

reaction of substituted-aniline (8) with ethyl (l-methyl-5-nitroimidazole-2- carbonyl) acetate (9) gave 4-hydroxy-2-(l-methyl-5-nitro-2-imidazolyl)- substituted-quinolines (lo), which were converted to compound 11 with phosphorus oxychloride. substituted-2-(l-methyl-5-nitro-2-imidazo1yl)-4.- methyl-(or phenyl-) quinolines (14) were prepared through the reaction of 2- acetyl-5-nitro-1-methyl-imi...

Plants are excellent sources of secondary metabolites that have been used for the treatment human diseases. The plant Momordica cymbalaria contains different types phytochemicals like phenols, steroids, flavonoids, alkaloids and tannins. present investigation was carried out to determine bioactive compounds in parts by Gas chromatography- Mass spectroscopy (GC-MS) technique. Chromatograms vivo ...

The effect of glutamate receptor agonists on the intracellular free calcium concentration ([Ca2+]i), measured with Indo-1, was studied in populations of cultured chick embryonic retina cells. The agonists of the ionotropic glutamate receptors, N-methyl-D-aspartate (NMDA), kainate, and alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) increased the [Ca2+]i through a composite effec...

Seven pyrrolizidine alkaloids (PAs) have been isolated from Lithospermum canescens and their structures determined by spectroscopical methods. Besides the known lycopsamine, O7-acetyl-lycopsamine and O7-acetylintermedine four new PAs were found. Their structures are O7-(3-hydroxy-3-methyl-butanoyl)-O9-(+)-trachelanthoyl-heliotridine (= O7-(3-hydroxy-3-methyl-butanoyl)-rinderine = canescine), O7...

3-Hydroxy-β-ionone, a flavor and fragrance compound with fruity violet-like characteristics, is widely applied in foodstuff beverages, currently produced using synthetic chemistry. In this study, novel lutein cleavage enzyme (EhLCD) was purified characterized from Enterobacter hormaechei YT-3 to convert 3-hydroxy-β-ionone. Enzyme EhLCD homogeneity by ammonium sulfate precipitation, Q-Sepharose,...

Case presentation: Male patient, 6 months old, admitted due to seizure associated with severe refractory hypoglycemia. Patient had been experiencing unusual sleepiness for 8 days, and vomiting after feedings. Brain CT showed prominence of the bilateral frontotemporal extra-axial space Sylvian fissures, EEG revealed a slow diffuse moderate disturbance background activity MRI extensive areas diff...
