Beverage companies sometimes receive reports that cloudy fruit juices have developed a “metallic flavour” when they are exposed to light, which results in consumer complaints. These degradations have been shown to be caused by photooxidation, in which singlet oxygen played an essential role. In the present study, aqueous antioxidants, such as crocin, crocetin, and norbixin, have been investigat...

Endoplasmic reticulum (ER) stress is a homeostatic mechanism, which is used by cells to adapt to intercellular and intracellular changes. Moreover, ER stress is closely linked to inflammatory pathways. We hypothesized that ER stress is an integral component of neuroinflammation and contributes to the development of neurological diseases. In autopsied brain specimens from multiple sclerosis (MS)...

objective: crocin, the carotenoid isolated from saffron, has numerous medicinal properties which include anticancer and antioxidant activities. some antioxidants, such as carotenoids, can act as pro-oxidants at higher dosages and therefore induce tissue damage. in this situation antioxidant defense systems in the liver activate to prevent tissue damage. this study investigates the possible toxi...

Introduction: Diabetes is a metabolic disease, which is directly correlated with increased physical disabilities and muscle tissue damage. The present study aimed to investigate the anti-apoptotic effects of interval and continued training and crocin on diabetic rats. Methods: In this study, 49 adult rats aged eight weeks with diabetes inducaed by a high-fat di...

Objective(s) Crocin bleaching assay (CBA) is a new method for determination of antioxidant capacity. In CBA, addition of hydrogen to the conjugated double bonds of crocin results in reduction of crocin and increase in the absorbance at 440 nm, which is considered as a measure of antioxidant potential. Here CBA method was set up using di-gentiobiosyl crocin or a-crocin from Iranian saffron. The...

Iridoid glycosides (mainly geniposide) and crocetin derivatives (crocins) are the two major active constituents in Gardenia jasminoides Ellis. In the present study, geniposide, crocins, crocin-1 and crocetin were separated from gardenia chromatographically. Then, mice were orally administrated with geniposide (400 mg/kg b.w.), crocins (400 mg/kg b.w.), crocin-1 (400 mg/kg b.w.) and crocetin (14...

PURPOSE Chronic stress has been reported to induce oxidative damage of the brain. A few studies have shown that Crocus Sativus L., commonly known as saffron and its active constituent crocin may have a protective effect against oxidative stress. The present work was designed to study the protective effects of saffron extract and crocin on chronic - stress induced oxidative stress damage of the ...

BACKGROUND Saffron is the dried stigma of Crocus sativus L. flower which commonly used as a natural remedy to enhance health and even fights disease in the Middle-East and Southeast Asian countries. METHODS This study was aimed to investigate protective effect of saffron extract and crocin in fatty liver tissue of high-fat diet induced obese rats. A total of 36 healthy male Sprague Dawley r...

BACKGROUND Crocin and safranal are the active substances of saffron and have many biological properties. In the present study, we compared the effects of crocin, safranal and diclofenac on local inflammation and its induced pain in rats. METHODS Local inflammation was induced by intraplantar (ipl) injection of carrageenan (100 μl, 2%). Paw thickness was measured before and after carrageenan i...

Post-traumatic stress disorder (PTSD) occurs following life-threatening events. The activity of the hypothalamic-pituitary-adrenal (HPA) axis, which serves as the first line of defense against stress, is dysfunctional in this disorder. The current study aimed to investigate the role of Crocin in normalizing HPA function in an animal model of PTSD induced by electric foot shock. Rats were treate...
