Three varieties of Hibiscus sabdariffa were analyzed for their phytochemical content and inhibitory potential on carbohydrate-digesting enzymes as a basis for selecting a variety for wine production. The dark red variety was chosen as it was highest in phenolic content and an aqueous extract partially inhibited α-glucosidase (maltase), with delphinidin 3-O-sambubioside, cyanidin 3-O-sambubiosid...

Malaria is a neglected tropical disease that still demands serious efforts to tackle successfully, including the need for new antimalarial lead compounds combat drug-resistant Plasmodium. Intensive phytochemical and pharmacological investigation into Indonesian medicinal plants Swietenia mahagoni Pluchea indica successfully revealed 5 constituents. Antimalarial bioassays indicated 34,5-tri- O-c...

In vitro antioxidant activities and neuronal cell protective effects of ethanol extract from roasted coffee beans were investigated. Colombia arabica coffee (Coffea arabica) green beans were roasted to give medium (230°C, 10 min), city (230°C, 12 min) and french (230°C, 15 min) coffee beans. Total phenolics in raw green beans, medium, city and french-roasted beans were 8.81±0.05, 9.77±0.03, 9.9...

The aim of this study was to assess the phenolic composition and nutraceutical potential of tinctures from fruits in two stages of maturity (F3, younger; F25, older), green husks (GH), and leaves (L) of Juglans regia L. In all extracts gallic, protocatechuic, 3-caffeoylquinic, 3-ρ-coumaroylquinic, 4-caffeoylquinic, 4-ρ-coumaroylquinic, and ρ -coumaric acids and quercetin-3-O-deoxyhexoside were ...

To clarify the suppression of postprandial blood glucose rise via alpha-glucosidase (AGH) inhibitory action by natural compounds, propolis was examined in this study. A single oral administration of propolis extract (50% methanol fraction on XAD-2 column chromatography) in Sprague-Dawley rats demonstrated a potent antihyperglycemic effect with the significant AUC(0-120 min) reduction of 38% at ...

High-pressure sodium (HPS) lighting is increasingly replaced by LED in lettuce greenhouse cultivation. In contrast to HPS lighting, LEDs do not heat radiation. Therefore, the leaf temperature significantly lower under LEDs. This raises question of whether has a positive impact on reduction water consumption during production. this paper, we investigated and found that produced was (−15%) than w...

Of all plant constituents, coffee has one of the highest concentrations of chlorogenic acids. When roasting coffee, some of these are transformed into chlorogenic acid lactones (CGL). We have studied the formation of CGL during the roasting of coffee beans in Coffea arabica cv. Bourbon; C. arabicacv. Longberry; and C. canephora cv. Robusta. Individual CGL levels were determined by comparison of...

In this research, a number of chemical compounds were estimated and identified in the crude extract both E. helioscopia peplus species, as it was noted that there about twenty alkaloid them, It was, also, three present species. had highest concentration alkaloids: Scopalamine, Colchicino theobromine. Presence following alkaloids observed Species helioscopia, namely; Metamfepramone, Phencyclidin...

Amid trends in non-dairy probiotic foods and functional coffees, it is timely to develop a high-count probiotic, fermented coffee beverage. Here, we aimed enhance the viabilities of different lactobacilli strains brews by co-culturing with yeast, Saccharomyces boulardii CNCM-I745. The growth, survival, metabolic activities Lactiplantibacillus plantarum 299v, Lactobacillus acidophilus NCFM, Limo...
