An ultrasonic-assisted extraction (UAE) protocol using deep eutectic solvent (DES) was employed to extract phenolic compounds from foxtail millet bran (FMB). DES composed with betaine and glycerol in a 1:2 M ratio selected basing on the total content (TPC) yield, optimal technology investigated response surface methodology (RSM) Box-Behnken design (BBD). The optimized process obtained as follow...

Published methods to isolate DNA from insects are not always effective in xylophagous insects because they have high concentrations of phenolics and other secondary plant compounds in their digestive tracts. A simple, reliable and labor-effective cetyltrimethylammonium bromide-polyvinylpyrrolidone (CTAB-PVP) method for isolation of high quality DNA from xylophagous insects is described. This me...

Background and objective: Medicinal oils are one of the most common and special dosage forms in oral and topical therapies of Persian medicine (PM). The oil of Saussurea costus (bitter qust) root is prominent topical oil with different applications in PM. In this study, the oil of bitter qust was prepared according to ancient Persian medical texts. Methods:</st...

Background and objectives: The aim of this study was the phytochemical screening and determining the total antioxidant activity of prosopis. farcta a plant native to South Khorasan. It has been mentioned as a cure for diarrhea, measles, diabetes and some other diseases in home remedies. Neuroprotective and relaxing effects, increasing HDL, decreasing LDL and accelerati...

Antioxidant activity of different berry phenolics, including anthocyanins, ellagitannins, and proanthocyanins, toward both protein and lipid oxidation in different food model systems (liposomes and emulsions) was studied in this thesis. In addition, the partition of berry anthocyanins into different phases in the oil-in-water emulsion, and the effect of different milk proteins (lactalbumin, bov...

Chemoprevention has recently gained a new dimension due to the possibility of studying the mechanisms of action of chemopreventive agents at the molecular level. Many compounds have been proved to inhibit early stages of carcinogenesis in experimental models. These compounds include both recognized drugs (such as tamoxifen and nonsteroidal anti-inflammatory drugs) and natural constituents of ed...

Drymaria diandra is used in Nepalese traditional medicine to treat various ailments. The hexane, dichloromethane, ethyl acetate, methanol and 50% aqueous extracts of D. were prepared screened for the presence different classes phytochemicals. Methanol showed phenolics, flavonoids carbohydrates so their total contents estimated. highest amount phenolics found extract (190.58±2.21 mg GAE/g 69.25±...

Background & Aim: Osmotic stress in plants lead to increase free radicals and plants use different mechanisms to scavenge these radicals. So, researchers apply stresses especially drought stress to increase secondary metabolites such as phenolics, and antioxidants. One of the valuable medicinal plants is yarrow (Achillea tenuifolia) which is a perennial plant with different medicinal a...

BACKGROUND Hyperglycemia is a complicated condition accompanied with high incidence of infection and dyslipidemia. This study aimed to explore the phyto-constituents of Crataegus azarolus var. eu- azarolus Maire leaves, and to evaluate the therapeutic potentials particularly antimicrobial, antihyperglycemic and antihyperlipidemic of the extract and the isolated compound (3β-O-acetyl ursolic aci...

It would be desirable to establish and standardize methods that can measure the total antioxidant capacity level directly from vegetable extracts containing phenolics. Antioxidant capacity assays may be broadly classified as electron transfer (ET)- and hydrogen atom transfer (HAT)-based assays. The majority of HAT assays are kinetics-based, and involve a competitive reaction scheme in which ant...
