Anti-ulcer activity of the three different extracts of Ferula lehmannii Boiss leaf in rats.

Ferula lehmannii Boiss (FLB) is a perennial plant that belongs to the family Apiaceae, which is a traditional remedy used to treat gastric ulcers in Xinjiang. The main purpose of the research is to investigate the possible antiulcer effect of three different extracts, water decoction (WD), fresh liquid (FL), and chloroform extract (CE), using a model of acetic acid-induced gastric ulcer. 56 rats were divided into seven groups (n=8) and treated ranitidine and extracts of FLB. After 12 days of treatment, the ulcer index and biochemical parameters were evaluated. In all tested groups, the results indicated that the chloroform extract and water decoction highly significantly decreased the mucosal damage index as compared to the model group, restoration of glutathione per oxidase (GSH-PX) levels and super oxide dismutase (SOD) activity, and reduction of malondialdehyde (MDA) levels. The ulcer inhibition rate of water decoction group, fresh liquid and chloroform extract group reached 25.30%, 4.96% and 30.87%, respectively. The macroscopic observations were supported by histological findings. 44, 31, 32 compounds were identified through GC-MS analysis of different extracts. In conclusion, FLB exhibits potential anti-ulcer activity attributed to its high content terpenoid, phytosterin and fatty acid, the underlying antiulcer mechanism might be relevant to the reduction in inflammation and oxidative stress.
