Comparative Evaluation of Gastroprotective Potential of Dypsis lutescens (H. Wendl.) and Caryota Urens(L.) on Experimentally Induced Gastric Ulcer in Rats

Abstract

The present study was carried out to find out the gastroprotective effects of the leaves extracts of Dypsis lutescens (H.Wendl.) and Caryota Urens (L.) in aspirin-induced gastric ulcer in rats. The ethanolic and aqueous extracts were prepared from the leaves of Dypsis lutescens and Caryota Urens and were used for this study. All procured animals were divided into seven groups. Each group contain n = 6, all groups except the normal control treated with aspirin 150 mg/kg oral. Group, I served as the normal control group which received normal saline, group II served as negative control and group III as standard group receiving 20 mg/kg omeprazole and 4th to 7th groups treated with leaves extracts of Dypsis lutescens and Caryota urens respectively. Treatment was given to group II to group VII rats in every 24 h for seven days. After 24 h fasting, on the 8th-day stomach contents were aspirated under anaesthetic condition to check free and total acidity. Stomachs were opened in all sacrificed animals along the greater curvature to estimate ulcer index, percentage protection and histopathology studies.
 The results of the present study revealed that the severity of aspirin-induced ulceration was significantly (P < 0.05) decreased in Dypsis lutescens extracts treated groups in comparison with the control and Caryota urens treated groups. It was observed that the free and total acidity significantly decreased in the aqueous extract of Dypsis lutescens treated group when compared with the negative control and Caryota urens treated groups.
