Saffron, the spice produced from the red stigmas of the flower of Crocus sativus L. is a frequent target of fraud and mislabeling practices that cannot be fully traced using the ISO 3632 trade standard specifications and test methods. A molecular approach is proposed herein as a promising branding strategy for the authentication of highly esteemed saffron brands such as the Greek Protected Designation of Origin (PDO) "Krokos Kozanis". Specific ISSR (inter-simple sequence repeat) markers were used to assess for the first time, the within species variability of several populations of C...

Quality of saffron, a valuable food additive, could considerably affect the consumers' health. In this work, a novel preprocessing strategy for image analysis of saffron thin layer chromatographic (TLC) patterns was introduced. This includes performing a series of image pre-processing techniques on TLC images such as compression, inversion, elimination of general baseline (using asymmetric least squares (AsLS)), removing spots shift and concavity (by correlation optimization warping (COW)), and finally conversion to RGB chromatograms...

Crocus sativus is the only plant species which produces apocarotenoids like crocin, picrocrocin and safranal in significant amounts. These compounds impart organoleptic properties to saffron (dried stigmas of Crocus flower) making it world's costliest spice. Crocus apocarotenoids have tremendous medicinal properties as well. Effect of endophytes on Crocus apocarotenoid production and the molecular mechanism involved has not been reported so far. Here we studied the effect of an oleaginous fungal endophyte, Mortierella alpina CS10E4 on Crocus growth, apocarotenoid metabolism and tolerance to corm rot disease...

Histological procedures aim at providing good-quality sections that can be used for a light microscopic evaluation of tissue. These are applicable to identify either spontaneous or diseases-induced changes. Routinely, tissues are fixed with neutral formalin 10%, embedded in paraffin, and manually sectioned with a microtome to obtain 4-5 μm thick paraffin sections. Dewaxed sections are then stained with HE&S (hematoxylin-eosin and saffron) or can be used for other purposes (special stains, immunohistochemistry, in situ hybridization, etc...

With the flourishing development of (CH3NH3)PbI3, three-dimensional (3D) organic-inorganic perovskites with unique structure-property flexibility have become a worldwide focus. However, they still face great challenges in effectively inducing ferroelectricity. Despite the typical 3D perovskite structure and the ability of dabco (1,4-diazabicyclo[2.2.2]octane) to trigger phase transition, unfortunately [H2dabco]RbCl3 adopts a nonpolar crystal structure without ferroelectricity. Within the larger RbI3 framework, we assemble N-methyl-1,4-diazoniabicyclo[2...

OBJECTIVES: Crocin is derived from dried stigmas of Crocus sativus L. (saffron). It has long been used to prevent and treat various diseases. Although crocin is suggested as one of the most effective cancer therapeutic constituents of saffron stigma, its exact molecular mechanisms are not fully understood. In this study, we reviewed anticancer effects of crocin and its underlying molecular mechanisms. KEY FINDINGS: While several mechanisms may account for the antitumour activity of crocin, alteration of expression/activity of the genes and also epigenetic changes may be considered as necessary phenomena...

Inhibition of lactate dehydrogenase (LDH) represents an innovative approach to tackle cancer because this peculiar glycolytic metabolism is characteristic of most invasive tumor cells. An investigation into the biological properties of saffron extracts led to the discover of their LDH-inhibition properties. In particular, the most important saffron components, crocetin, was found to inhibit LDH (IC50 = 54.9 ± 4.7 μM). This carotenoid was independently produced by chemical synthesis, and its LDH-inhibition properties manifested via its antiproliferative activity against two glycolytic cancer cell lines (A549 and HeLa, IC50 = 114...

Phospholipids are shown by solvent penetration experiments to form lamellar phases and spontaneously spawn vesicles in a wide range of deep eutectic solvents (DESs) composed of alkylammonium halide salts and glycerol or ethylene glycol, which are shown to be nanostructured by X-ray scattering. In contrast with molecular solvents, the chain melting temperature of each phospholipid, which determines the stability of the swellable bilayer phase, depends on the structure of the cation, anion, and molecular H-bond donor that constitute the DES...
