Aim of this study is to confirm and investigate the diuretic effect of crocine which is the pharmacologically active component of Crocus sativus L. (saffron) and to study the possible mechanism of action in relation to urinary nitrite. Twenty four rats were divided into 3 groups; control, hydrochlorothiazide and crocine treated groups. Assay of the diuretic activity of crocine was performed by ...

This study was designed to investigate the therapeutic effects of saffron (Crocus sativus L.) and its main constituent crocin on neuropathic pain behavioral responses induced by chronic constriction injury (CCI) in rats. Adult male Wistar rats (200 to 250 g) were randomly assigned into 5 groups: Sham + saline, CCI + saline, CCI+ saffron (30 mg/kg), CCI + crocin (15 mg/kg) and CCI + crocin (30 m...

Crocin, the main pigment of Crocus sativus L., has been shown to have antiproliferative effects on cancer cells, but the involved mechanisms are only poor understood. This study focused on probable effect of crocin on the immortality of hepatic cancer cells. Cytotoxicity of crocin (IC50 3 mg/ml) in hepatocarcinoma HepG2 cells was determined after 48 h by neutral red uptake assay and MTT test. I...

OBJECTIVE The present study was designed to investigate the putative antidepressant effects of crocin and crocetin, two major active ingredients of Crocus sativus L. (saffron) using mice in two different regimens of acute and sub-acute administration. MATERIAL AND METHODS In acute treatment, antidepressant-like activities of crocin and crocetin (10, 20 and 40 mg/kg, i.p.) were evaluated using...

OBJECTIVES Recently, a great deal of interest has been developed to isolate and investigate novel bioactive components from natural resources with health beneficial effects. Saffron is the dried stigma of Crocus sativus L. and has been used for centuries in traditional medicine mainly for its healing properties, as well as for the treatment of various pathological conditions. Objectives of the ...

In this study, the effect of crocin, a substance found in Crocus sativus L. stigmata on nervous system development and regeneration was investigated. Crocin is a glycosyl ester of the polyene dicarboxylic acid crocetin and is one of the few families of carotenoids found in nature, which are freely soluble in water. In the first experiment, the effect of crocin (30 microM, 60 microM and 120 micr...

Article type: Original article Objective(s): Alzheimer's disease (AD) is the most common age‐related neurodegenerative disorder. One of the hallmarks of AD is an abnormal accumulation of fibril forms of tau protein which is known as a microtubule associated protein. In this regard, inhibition of tau aggregation has been documented to be a potent therapeutic approach in AD and tauopathies. Unfor...

Introduction: The cholinergic system plays an important role in learning and memory. Administration of either extracts of Crocus Sativus (Saffron) or its constituent, crocin, reduced ethanol-induced memory impairment. Based on the above findings, we investigated the effect of crocin in antagonizing spatial learning and memory impairment induced by scopolamine, a cholinergic receptor antagonist,...

Saffron, the dried red-orange stigmas of Crocus sativus L, has been known as a flavoring agent, food coloring and traditional herbal medicine. Pharmacological effects of saffron are mainly attributed to crocin, crocetin, picrocrocin and safranal. These components especially crocin, have significant effects including antidepressant and anticonvulsant, analgesic, anti-cancer and other therapeutic...

background: obesity is pandemic worldwide and a strong risk factor for cardio-metabolic disorders. the few approved anti-obesity drugs have poor efficacy and safety profile. thus, there is an urgent need for new anti-obesity agents. according to the traditional medicine and a clinical trial, saffron may have anorexigenic and anti-obesity effects which need further investigation. objectives: eva...
