A new natural compound, named 6-O-(3",4"-dimethoxycinnamoyl) catalpol, was isolated from the defatted alcoholic extract of the flowering parts of Buddleja asiatica Lour. (family Scrophulariaceae). Other separated known compounds included steroids (beta-sitosterol, stigmasterol, stigmasterol-O-glucoside, beta-sitosterol-O-glucoside), iridoid glucosides (methyl catalpol, catalpol, aucubin), pheny...

Phenolic compounds were extracted from defatted flaxseeds using ethanol-dioxane (1:1, v/v). The crude extract obtained was purified using Amberlite XAD-16 column chromatography with water and methanol as mobile phases. RP-HPLC and SE-HPLC showed a lignan macromolecule (LM) as a dominant phenolic compound in the purified extract. After the alkaline hydrolysis of LM caffeic acid glucoside (CaAG) ...

Chromatographic separation of an aqueous MeOH extract of Wisteria sinensis leaves has yielded six known flavonoids, two triterpene aglycones and the new acylated flavone glycoside chrysoeriol-7-O-[2''-O-(5'''-O-caffeoyl)-β-Dapiofuranosyl]-β-D-glucopyranoside (1). All metabolites were isolated for the first time from the genus Wisteria. Their structures were established on the basis of their chr...

Background:Oncoba spinosa, an endangered medicinal plant whose secondary metabolites have not been extensively profiled, and which is hitherto yet to be examined for cytotoxicity, is being investigated in this study. Methods: Leaves of Oncoba spinosa (800 g) were extracted with 95% aqueous methanol. The crude extract was partitioned with n-hexane and the resultant defatted extract was extensive...

Defatted rice bran was treated with subcritical water between 120 and 240°C. The extraction temperature af fected the total carbohydrate and protein contents of the extracts. In the tested temperature range, the total carbohydrate and protein contents were the highest at 180°C and 210°C. The DPPH radical scavenging activity of the extracts increased with increasing extraction temperature up to ...

The present study aimed to investigate the direct in vitro effects of several distinct Citrullus colocynthis seed extracts on glucose-stimulated insulin release from pancreatic islets isolated from rats. Six extracts were tested, a crude aqueous, defatted aqueous, ethyl acetate, H2O-methanol and n-butanol extract and an extract containing a major component (fraction A) identified by gel chromat...

extract 0.3%, yeast extract 0.5% and CaCO30.4%, pH 7.0, incubated on a reciprocal shaker (300 rpm) at 27°C for 48hours. The culture broth was transferred into a 500 ml-Erlenmyer flask containing 100ml of the same seed medium, and incubated at 27°C for 48 hours on a rotary shaker (210rpm). Vegetative seed culture (2%, v/v) was transferred into a 30-liter jar fermentor containing 20 liters of a p...

This study investigates the useful of protein-rich extract from sesame seed as only source nourishment for development lactic acid bacteria. Unstructured mathematical and Gompertz model were proposed part screening process to characterize growth, production, pH drop, nutrient consumption by Lactobacillus plantarum in defatted order compare their appropriateness manufacture a fermented beverage....
