Abstract

Quisqualis indica L., Syn. Combretum indicum (L.) DeFilipps., known as Rangoon creeper or Chinese Honeysuckle, is an abundant source of phenols and flavonoids thathave crucial role in free radical scavenging. Therefore, here we investigated whether extract of Q. indica flower has any role against esophagitis through scavenging of free radical oxygen species. In this study, we elucidated the effect of ethanolic flower extract of Q. indica on experimental esophagitis in albino Wister rats. The fasted animals divided into six groups and received carboxymethyl cellulose (CMC) (0.25%, 3 mL/kg, Sham control) or toxic control or pantoprazole (30 mg/kg) or flower extract of different doses (100, 200 and 300 mg/kg) were subjected to pylorus and fore stomach ligation. All the animals were sacrificed after 8 h and evaluated for various parameters such as total acidity, free acidity, gastric pH, volume of gastric juices and esophagitis index. Esophageal tissues were subjected to estimation of various oxidative stress parameters like malonaldehyde (MDA), glutathione (GSH), catalase (CAT), superoxide dismutase (SOD) and protein carbonyl (PC). In a separate experiment, in vitro antioxidant assays such as DPPH and H2O2 assays, total phenolic and flavonoid contents were also conducted. The results revealed that treatments with pantoprazole and flower extracts significantly inhibited the gastric secretion, total acidity and esophagitis index. Various oxidative stress parameters also restored to normal level in the treated groups. This action could be due to the presence of higher phenolic and flavonoid contents. All these findings collectively suggest that the flower extract of Q. indica possibly possess anti-esophagitis potential.
