New Hydrogels Enriched with Antioxidants from Saffron Crocus Can Find Applications in Wound Treatment and/or Beautification.

Numai utilizatorii înregistrați pot traduce articole

Saffron extracts have a long history of application as skin protectant, possibly due to their ability to scavenge free radicals. In this work, the performance of a hydrogel enriched with antioxidant compounds isolated from saffron crocus (Crocus sativus L.) petals was tested. These hydrogels could

Comparative Analysis of Native Crocus Taxa as a Great Source of Flavonoids with High Antioxidant Activity.

Numai utilizatorii înregistrați pot traduce articole

Native Crocus taxa are abundant in regions with moderate and dry climate; however, their potential in the food industry has thus far been neglected. The objective of this study was to compare the quantitative and qualitative flavonoid content and antioxidant and cytotoxic activity in organs of

Antioxidant activity of bulbs and aerial parts of Crocus caspius, impact of extraction methods.

Numai utilizatorii înregistrați pot traduce articole

Crocus genus (Iridaceae) is comprises approximately 80 species. In this study in vitro antioxidant activities of extracts from C. caspius bulbs and aerial parts were investigated. Ultrasonically assisted extraction (US), percolation method (PE) and polyphenolic fraction (PP) were used. Antioxidant

Antioxidant, anticholinesterase and tyrosinase inhibition activities, and fatty acids of Crocus mathewii - A forgotten endemic angiosperm of Turkey.

Numai utilizatorii înregistrați pot traduce articole

Context We report the first ever chemical/biochemical study on Crocus mathewii Kerndorff (Iridaceae) - a Turkish endemic angiosperm. This plant has never been explored for its phytochemistry and bioactivities. Objective This study explores C. mathewii corm and aerial parts for the chemical and

Background

Diabetes is regarded as an epidemiological threat for the twenty-first century. Phytochemicals with known pharmaceutical properties have gained interest in the field of alleviating secondary complications of diseases. Such a substance is crocin, a basic constituent of

Effect of extrusion on the physicochemical and antioxidant properties of value added snacks from whole wheat (Triticum aestivum L.) flour.

Numai utilizatorii înregistrați pot traduce articole

Nutritional quality of snacks prepared from cereals can be improved by the addition of crude lycopene (CL), tomato powder (TP) and saffron extracts (SE) which are known for their high photochemical content. The study was undertaken to prepare extruded snacks from whole wheat flour enriched with CL,

A modified, economic, sensitive method for measuring total antioxidant capacities of human plasma and natural compounds using Indian saffron (Crocus sativus).

Numai utilizatorii înregistrați pot traduce articole

BACKGROUND Free radicals are involved in various human diseases that can possibly be prevented by antioxidants. There are many but rather expensive methods to determine total antioxidant capacity of human plasma (for endogenous antioxidant levels) or plant extracts/natural compounds (for antioxidant

Saffron supplements modulate serum pro-oxidant-antioxidant balance in patients with metabolic syndrome: A randomized, placebo-controlled clinical trial.

Numai utilizatorii înregistrați pot traduce articole

OBJECTIVE We have investigated the effect of a saffron supplement, given at a dose of 100 mg/kg, on prooxidant-antioxidant balance (PAB) in individuals with metabolic syndrome. METHODS A randomized, placebo-controlled trial design was used in 75 subjects with metabolic syndrome who were randomly

Antioxidant properties of crocin from Gardenia jasminoides Ellis and study of the reactions of crocin with linoleic acid and crocin with oxygen.

Numai utilizatorii înregistrați pot traduce articole

Crocin-a water soluble carotenoid-is found in the fruits of gardenia (Gardenia jasminoides Ellis) and in the stigmas of saffron (Crocus sativus Linne). For crocin purification, gardenia fruits are extracted with 50% acetone, followed by ether washing, ion exchange, and separation by preparative

Inhibition of iron induced lipid peroxidation and antioxidant activity of Indian spices and Acacia in vitro.

Numai utilizatorii înregistrați pot traduce articole

The spices used in the Indian foods such as Star anise (Illicium verum), Bay leaves (Cinnamomum zeylanicum) and Cobra's saffron (Mesua ferrea), and Acacia (Acacia catechu), which have medicinal value, were used as test samples, to find their effect on in vitro lipid peroxidation (LPO). Rat liver

Enhancement of neuroprotection, antioxidant capacity, and water-solubility of crocins by transglucosylation using dextransucrase under high hydrostatic pressure

Numai utilizatorii înregistrați pot traduce articole

Crocin, one of the major carotenoid pigments of Crocus sativus (saffron), is responsible for antioxidant activity, neuroprotection, and the inhibition of tumor cell proliferation. In order to improve the functionality of crocin, α-glucosyl-(1→6)-trans-crocins (C-Gs) were synthesized using sucrose

Antioxidant effect of crocin on bovine sperm quality and in vitro fertilization.

Numai utilizatorii înregistrați pot traduce articole

Reactive oxygen species (ROS) production above critical levels affects the genetic and functional integrity of spermatozoa by causing oxidative stress. Spermatozoa are susceptible to oxidative stress in terms of motility and fertilization capacity. Crocin (crocetin di-gentiobiose ester), a main

Numai utilizatorii înregistrați pot traduce articole

Crude extracts from Inula aucherana, Fumaria officinalis, Crocus sativus, Vicum album, Tribulus terestris, Polygonatum multiflorum, Alkanna tinctoria and Taraxacum officinale were screened for their in vitro antioxidant and antimicrobial properties. Total phenolic content of extracts from these

Orally administered pressure-blanched white saffron ( Curcuma mangga Val.) improves antioxidative properties and lipid profiles in vivo

Numai utilizatorii înregistrați pot traduce articole

This research focused on studying the effects of orally administered pressure-blanched white saffron on the antioxidative properties and lipid profiles of wistar rats. White saffron was blanched in autoclave for 2.5, 5, 7.5, and 10 min at 100, 105, 110, 115, and 120 °C, which are equivalent to
