Saffron, the stigma of Crocus sativus Linné (Iridaceae family), has been known to inhibit aggregation of β-amyloid, a nerve tissue protein. α-Synuclein (αS) is a 140-amino acid protein found abundantly in various regions of the brain. Its abnormal aggregation and accumulation in nerve tissue are
Extracts from saffron, the dried stigmata from Crocus sativus L. are recognized as valuable tools for pharmaceutical development in neuroprotection and antidepressive therapy. One major lead compound is crocin-1 (1), which gets metabolized to the C20-dicarboxylic acid trans-crocetin (2) being
In the present study, the effects of an ethanol and aqueous extract of saffron Crocus sativus and its constituents safranal and crocin on the stress-induced reduction in food intake, weight gain and anorexic time in mice were investigated. Male albino mice (20-25 g) were irregularly exposed to a
The limited arsenal of synthetic antifungal agents and the emergence of resistant Candida strains have prompted the researchers towards the investigation of naturally occurring compounds or their semisynthetic derivatives in order to propose new innovative hit compounds or new antifungal
Saffron is the dried stigmas of Crocus sativus and is the most expensive spice in the world. Its red color is due to crocins, which are apocarotenoid glycosides that accumulate in the vacuole to a level up to 10% of the stigma dry weight. Previously, we characterized the first dedicated enzyme in
Crocins are important apocarotenoids in the extract of saffron (Crocus sativus L.) and fruits of gardenia (Gardenia jasminoides E.). Crocins have shown versatile biological activities and thus they have been considered to be promising therapeutics for neurodegenerative and heart A simple, sensitive and specific high-performance liquid chromatography-UV (HPLC-UV) method has been developed for the first time to simultaneously quantify the five major biologically active ingredients of saffron, namely crocin 1, crocin 2, crocin 3, crocin 4 and crocetin. Calibration curves were
Four new compounds, crocusatins F (1), G (2), H (3), and I (4a), together with 21 known compounds, were isolated from an aqueous extract of the stigmas of Crocus sativus (saffron). The structures of 1-4 were established by spectral methods. The tyrosinase inhibitory activities of all 25 compounds
Saffron is an expensive spice. Its primary effective constituents are crocin I and II, and the contents of these compounds directly affect the quality and commercial value of saffron. In this study, near-infrared spectroscopy was combined with chemometric techniques for the determination of crocin I
Crocins are the primary coloring ingredients of saffron. The low-glycosylated members of this compound family, such as crocin-1(crocetin mono-glucosyl ester) and crocin-2' (crocetin di-glucosyl ester), are rarely distributed in nature and attracting interest in their therapeutic uses. In our
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
Depression is the leading cause of mental health-related disease globally, and it affects an estimated 300 million people worldwide. However, its physiological causes are not fully understood. Since available antidepressants fail to achieve complete disease remission, treating diversification of
A microwave-assisted extraction method was optimised for the recovery of bioactive compounds from Crocus sativus L. stigmas with the use of water/ethanol mixture. HPLC-DAD was employed to evaluate the extraction parameters, in particular, solvent type and volume, and the duration of the procedure.
Background: As the main ingredient of Crocus sativus L. (Iridaceae) extract, crocin- I (CR) has been reported to show various pharmacological activities. The aim of this study was to investigate the hypoglycemic and renal protection properties of CR in db/db
Glucocorticoids (GCs) are widely used as anti-inflammatory and immunosuppressive drugs. However, chronic treatment with GCs in clinical settings has a series of side effects, such as metabolic disorders, gut microbiota dysbiosis and neurological impairment. Therefore, searching for a functional
