Omega-3 fatty acids (FAs) have been shown to prevent cardiovascular disease. The most commonly used omega-3 fatty acids like eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are highly vulnerable to oxidation and therefore, have short shelf life. Recent advances in nanoliposomes provided a biocompatible system for stabilizing omega-3 FAs. Several methods could be implemented to prepar...
Background: Antioxidants are molecules which able to control free radicals and prevent the oxidants of other molecules considering undesirable effects of synthetic anti oxidant. In recent years using of natural anti oxidant gets the great importance. The secondary metabolisms of plants are rich sources of phenol and flavonoids considered as the most important natural antioxidant. Objective: In...
Phytochemicals from tropical fruits and their by-products have shown the potential to use as antimicrobial natural. This study aimed optimize recovery of phenolic compounds (total polyphenols flavonoids) cashew apple using ultrasound-assisted extraction promote functional attributes its coproducts evaluate antioxidant potential. An experimental design applying a response surface methodology was...
The aim of the work is development express, selective, reproducible methods for determination riboflavin by HPLC in a multivitamin preparation, dragee “Revit”. Materials and methods. Degasser, binary pump, autosampler, thermostated column compartment, diode array detector. Chromatographic Zorbax SB-C18, 30 mm × 4.6 mm, 1.8 µm. Samples were prepared using analytical electronic scales Kern ABT 10...
Studies have shown the importance of oxygenated compounds in beverage and food products. Citrus rootstocks seem to have a profound influence on oxygenated compounds in plants. The goal of the present study was to investigate the effect of rootstocks on the oxygenated compounds in Citrus clementina. Flower oil components were extracted using an ultrasonic bath and eluted with n-pentane: diethyl...

Background & Aim: Medicinal plants are most valuable and useful sources as productive factors of drugs. Production and extraction of secondary metabolites have a huge economical importance in recent years. Carvone is a compound in Bunium persicum fruit and shoot and, it is one of the wide range varieties of valuable and useful secondary metabolites. Due to limited crop production, usin...
