In this study, a novel polysaccharide fraction from Ocimum album seed was extracted and then purified by Cellulose DEAE-52 Sephadex G-200 anion exchange chromatography. The structural, physicochemical antioxidant properties of the main (OAP-1A) were evaluated. contained 94.3% carbohydrate, 3.56% moisture 2.14% ash result gel permeation chromatography (GPC) showed average molecular weight 593 kD...

Four new steroidal glycosides such as 3-O-6-deoxy-3-O-methyl-β-D-allopyranosyl-(1 → 4)-β-D-oleandropyranosyl-(1 → 4)-β-D-cymaropyranosyl-(1 → 4)-β-D-cymaropyranoside-12-β-tigloyl-14-β-hydroxy-17-β-pregnane (1), 3-O-6-deoxy-3-O-methyl-β-D-allopyranosyl-(1 → 4)-β-D-oleandropyranosyl-(1 → 4)-β-D-cymaropyranosyl-(1 → 4)-β-D-cymaropyranoside-12-β-(2'-amino)-benzoyl-14-β-hydroxy-17-β-pregnane (2), 3-...

introduction the compounds known as β-adrenergic agonists (β-aa) are organic molecules that have the ability to bind to β-adrenergic receptors (β-ar) and start biochemical reactions that will result in increase of accretion of skeletal muscle and reduction in accretion of fat. the anabolic responses to β-aa are temporary, with a peak time occurring during the first 14 days, after which there is...

four known flavonoids: quercetin 3-o-β-d-rutinoside (q3rut), myricetin 3-o-β-d-galactopyranoside (m3gal), quercetin 3-o-β-d-galactopyranoside (q3gal) and quercetin 3-o-β-d-glucopyranoside (q3glc), for the first time were isolated from aerial parts of euphorbia microsciadia. the chemical structure of them was elucidated on the basis of 1 and 2 d-nmr spectra and different spectroscopic techniques...

β-glucosidase is involved in the degradation of cellulose in soil and has the potential for monitoring biological soil quality. the objective of this study was to determine the effects of barley residue placement, burning, nitrogen fertilizer and tillage management on β-glucosidase enzyme after a period of 90 days. a field experiment was carried out based on a completely randomized design with ...

objective(s): the aim of this work was to investigate the effect of the natural and the chemically modified form of cyclodextrins namely; β-cyclodextrin (β-cd) and hydroxypropyl-β-cyclodextrin (hp-β-cd) respectively on the solubility and dissolution rate of aripiprazole; an antipsychotic medication showing poor aqueous solubility.   materials and methods: phase solubility of aripiprazole with t...

In this study, some biochemical responses of Beta-Cyfluthrin (β-CF), which is a commercial insecticide in Dreissena polymorpha, were investigated. The 96 hour LC50 value β-CF on D. polymorpha was calculated as 509.62 µg L-1. exposed to subletal concentrations (1/16, 1/8 and 1/4 value: 32, 64 128 L-1) for 24 hours. Malondialdehyde (MDA) reduced glutathione (GSH) levels Acetylcholinesterase (AChE...
