Anthocyanin colors and factors which stabilize and enhance these labile pigments were studied in this thesis. Berry anthocyanin colors were successfully improved by phenolic acid and natural plant extract addition. The results obtained contribute to the understanding of the chemical behavior of anthocyanins. The color quality of black currant wine was improved by the addition of crowberry juice...
Analysis of anthocyanins responsible for the purple flesh color is important for breeding programs and development of value-added products. This study aimed to optimize the conditions for anthocyanin extraction from purple-fleshed sweet potatoes (PFSP) using pressurized-liquid extraction (PLE) method and quantify anthocyanins in various genotypes. Freeze-dried powders of PFSP genotypes were ext...
recent investigations have shown that plants have antioxidant properties and could decrease oxidative stress in different human diseases. the present work was identified the chemical composition compounds and evaluated the various antoxidative activities of ferula-assa-foetida leaves hydroalcoholic extract (flhe) and ferula-assa-foetida leaves essential oil (fleo) . radical scavenging activity ...
abstract sensitive and precise voltammetric methods for the determination of trace amounts of furaldehydes, mainly as furfural (f) and 5-hydroxymethyl-2-furaldehyde (hmf), in waste waters and other matrices is described. determination of total furaldehyde at < ?g g-1 levels in alkaline buffered aqueous media was individually investigated. by the use of ordinary swv and adsorptive square wave ...
this study was conducted to evaluate the hypoglycemic, hypocholesterolemic and antioxidant properties of mentha spicata (labiateae) leaves aqueous extract (msla) in alloxan-induced diabetic rats. in this study, hyperglycemia was induced in male rats by intraperitoneal injection of alloxan monohydrate (150 mg/kg). the aqueous extract of m. spicata was orally administered at a dose of 300 mg/kg b...
Background and Objectives: Phellinu s Quel is a large and widely distributed genus of the family Hymenochaetaceae under the class of Basidiomycetes with more than 359 species. The Phellinu s species have anticancer, antioxidant and antibacterial effects . Hitherto, 12 Phellinus species have been reported from the north of Iran. Due to their great medicinal effects and lack of investigation on...
In order to study three vegetative rootstocks M9, M7 and MM106 on some growth and biochemical Characteristics of Apple cvs. "Golden delicious" and "Red Delicious", an experiment in factorial design based on randomized complete blocks with four replications in orchard of Mashhad agricultural research center was performed in 2021. Some characteristics: including trunk diameter, current shoot grow...
in this study, the concentrations of 25, 375 and 500 ml l -1 of cola+ 2000 mg l -1 of peppermint essence and concentrations of 30, 45 and 60 ml l -1 of apple extract +2000 mg l -1 rosemary essence on alstroemeria cut flowers (cv. balance) were investigated to verify the use of natural ingredients in flowers preservative solutions. this experiment was conducted in the laboratory of gorgan univer...
Introduction: Development of new medicines with fewer adverse effects and more efficacies is needed for the treatment of psychiatric disorders. The present study aimed to investigate the putative antidepressant and anxiolytic effects of methanolic extract of Salvia spinosa L. (SS) in mice. Materials and Methods: Elevated plus-maze (EPM) and open field tests (OFT) were conducted to evaluate anti...
