High-performance liquid chromatography with photodiode-array detection was used to separate picrocrocin (bitter-tasting component, glucoside of safranal), cis/trans-crocins (carotenoids, glucosyl esters of crocetin) and safranal (flavour, monoterpene aldehyde) of saffron. All components of pure red
This study was designed to examine the effect of aqueous extract of Crocus sativus stigmas (CSE) and crocin (trans-crocin 4) on methyl methanesulfonate (MMS)-induced DNA damage in multiple mice organs using the comet assay. Adult male NMRI mice in different groups were treated with either
Crocus sativus L. natural compounds have been extensively used in traditional medicine for thousands of years. Recent research evidence is now emerging in support of its therapeutic potential for different pathologies including neurodegenerative diseases. Herein, the C. sativus L.
Saffron, the dried stigmas of Crocus sativus L., is used as a condiment spice. The major bioactive compounds are crocins, picrocrocin and safranal, which are responsible for the sensory profile of saffron (color, flavor and aroma, respectively), and also health-promoting properties. In this paper,
To prepare a lyophilized saffron aqueous extract (SFE) and determine its chemical profile and serum and tissue pharmacokinetics after intravenous and oral administration to C57/Bl6J mice.Lyophilized SFE was prepared, characterized using semi-preparative Trans-crocin 4 (TC4) is an important carotenoid constituent of saffron showing potential activity against Alzheimer's Disease (AD) due to its antioxidant and antiamyloidogenic properties. Metabolomics is an emerging scientific field that enhances biomarker discovery and reveals underlying
Changes that may be expected in crocetin esters (crocins) upon digestion were examined in saffron aqueous extracts for the first time. Chemical characterization of total and individual crocins and other bioactive compounds was achieved by UV-vis spectrophotometry, RP-HPLC-DAD, and LC-ESI-MS.
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
Cancer is a very important national health problem in Mexico, while a significant increase in the total and childhood cancer mortality has been recorded during the last decades. Chemoprevention, defined as the use of natural or synthetic agents to prevent or to block the development of cancer in
Among the different species of Crocus, only C. sativus has been extensively studied for the composition and the biological properties of its styles, since these constitute the well-known spice saffron, which is widely used in the Mediterranean, Indian and Chinese diet. With high performance liquid
This study demonstrates a simple method for one-step isolation of the main secondary metabolites of a hydroalcoholic extract of Crocus sativus stigmas (saffron) using step-gradient centrifugal partition chromatography. The analysis was performed in dual and elution-extrusion mode, using five
Saffron's quality depends on the concentration of secondary metabolites, such as crocins, picrocrocin and safranal. The aim of this research was to evaluate the influence of drying conditions on the secondary metabolite contents of saffron produced in the area of Cascia, in central Italy. Different
Crocus sativus stigmas are one of the widely known spices (saffron) and consist of unusually polar carotenoids. Alzheimer's disease is characterized pathologically by deposition of amyloid beta-peptide (Abeta) fibrils. Oxidation is thought to promote Abeta fibril formation and deposition. To
