abstract

background: saffron is the dried stigmata of the flowers of saffron (crocus sativus l., iridaceae). saffron is well known for the treatment of gastric disorders in traditional medicine.   objectives: in the search for new potential antiulcer agents, the effects of the ethanol extract of saffron and its active constituents crocin and safranal as compared with omeprazole against gastric ulcer induced by indomethacin in non-diabetic and streptozocin diabetic rats were studied.   methods: the effects of pretreatment with saffron extract ( 25, 100 or 250 mg/kg, p.o.) , crocin ( 2.5, 5 or 10 mg/kg, p.o.) and safranal ( 0.25, 2, 5 ml/kg, p.o.) and omeprazole (30 mg/kg, p.o.) 30 min before administration of indomethacin (40 mg/kg, p.o. in non-diabetic rats and 15 mg/kg, p.o. in diabetic rats) on gastric lesions, increase of lipid peroxidation and decrease of glutathione levels induced by indomethacin in non-diabetic and diabetic rats were evaluated.   results: saffron extract, crocin, safranal and omeprazol prevented the gastric lesions, increase of lipid peroxidation and decrease of glutathione levels induced by indomethacin in non-diabetic and diabetic rats as compared with the control group (p < 0.01). the effects of saffron extract, crocin and safranal on the gastric ulcer index, lipid peroxidation and glutathione levels were comparable to omeprazole. conclusions: saffron, crocin and safranal may prevent the gastric mucosa damage due to their antioxidant properties by increasing the gluthatione levels and diminishing the lipid peroxidation in the rat gastric mucosa.

Anti-hyperglycemic Effects of Saffron and its Active Constituents, Crocin and Safranal, in Alloxan-Induced Diabetic Rats

Background: Saffron is the dried stigmata of the flowers of saffron (Crocus sativus L., Iridaceae). Saffron and its major active constituents, crocin (crocetin glycoside), crocetin and safranal, have a variety of pharmacological effects including high antioxidant properties and crocetin has insulin sensitizing effect possibly due to its antioxidant activity. Oral crocin is not absorbed and is h...

Effects of crocin and safranal, saffron constituents, on the formalin-induced orofacial pain in rats

Objective: Crocin and safranal are the main components of saffron, and have many biological functions such as anti-inflammatory and antioxidant activities. In the present study, we investigated the effects of crocin, safranal, morphine, diclofenac and naloxone in combined and separately on formalin-induced orofacial pain in rats. Materials and Methods: Subcutaneous injection of a diluted formal...
