Protective effect of Corchorus capsularis L. leaves on ethanol-induced acute gastric mucosal lesion in rats.

ABSTRACT: In Taiwan, Corchorus capsularis L. has long been cultivated and the leaves are consumed as edible vegetable. This study is to investigate the protection effect of extract of C. capsularis leaves (ECC) on ethanol-induced acute gastric mucosal lesion (AGML) in rats. The results of phytochemical determination in ECC for total polyphenol, flavonoid and polysaccharide were 59.88 ± 0.61 mg/g, 86.39 ± 18.0 mg/g and 320.89 ± 6.99 mg/g, respectively. ECC showed significant activity of 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging with IC₅₀ of 0.25 mg/ml. In vivo studies, Sprague-Dawley (SD) rats were randomly divided into five groups: sham, vehicle (control) and low-, medium-, and high-dose ECC (LECC, MECC, HECC; 200, 400, and 1,000 mg/kg/day, respectively). ECC was able to decrease significantly the ulcer index (UI) caused by 80% ethanol in a dose dependent manner. There was no significant effect on growth trend and food intake rate after the administration of ECC in the experimental period. The serum lipid parameters in ECC groups revealed significant increase in glutathione peroxidase (GPx), superoxide dilmutase (SOD) and catalase (CAT), and a decrease in malondialdehyde (MDA). Significant amelioration on pathological lesion score was found in ECC groups compared with the control group (P<0.05). The overall results indicate that ECC has protective effects on ethanol-induced AGML in rats, which could be associated with its antioxidant activity.

Project description:Zuojin Pill (ZJP), a traditional Chinese medicine formula, consists of Coptis chinensis Franch. and Evodia rutaecarpa (Juss.) Benth. in a ratio of 6:1 (w/w) and was first recorded in "Danxi's experiential therapy" for treating gastrointestinal disorders in the 15th century. However, the poor solubility of alkaloids from ZJP restricted the protective effect in treating gastritis and gastric ulcer. The aim of the study was to investigate the protective mechanism of mucoadhesive microspheres loaded with alkaloids from C. chinensis Franch. and E. rutaecarpa (Juss.) Benth. on ethanol-induced acute gastric mucosal injury in rats. Surface morphology, particle size, drug loading, encapsulation efficiency, in vitro drug release, mucoadhesiveness, and fluorescent imaging of the microspheres in gastrointestinal tract were studied. The results showed that the mucoadhesive microspheres loaded with alkaloids could sustain the release of drugs beyond 12 hours and had gastric mucoadhesive property with 82.63% retention rate in vitro. The fluorescence tracer indicated high retention of mucoadhesive microspheres within 12 hours in vivo. The mucoadhesive microspheres loaded with alkaloids could reduce the gastric injury by decreasing the mucosal lesion index, increasing the percentage of inhibition and increasing the amount of mucus in the gastric mucosa in an ethanol-induced gastric mucosal injury rat model. Moreover, the mucoadhesive microspheres loaded with alkaloids reduce the inflammatory response by decreasing the levels of tumor necrosis factor-? (TNF-?), interleukin 1? (IL-1?), downregulating the mRNA expression of inducible nitric oxide synthase, TNF-?, and IL-1? in gastric mucosa. All the results indicate that mucoadhesive microspheres loaded with alkaloids could not only increase the residence time of alkaloids in rat stomach, but also exert gastroprotective effects through reducing the inflammatory response on ethanol-induced gastric mucosal damage. Thus, these microspheres could be developed as a potential controlled release drug for treatment of gastric ulcer.
