Evaluation of Anti-Ulcer activity of Tephrosia purpurea Linn Pers Leaf Extract in Wistar Rats

Abstract

India is known for its traditional medicinal system – Ayurveda, Siddha and Unani. There are several references in our ancient literature about the miraculous curing properties of the plant-based drugs. “Rig Veda and Atharva veda” seems to be the earliest record of use of plant in the medicine. A stomach ulcer involves an erosion in a person’s gastrointestinal tract. ‘Peptic’ is derived from Greek word “Peptikos” who’s meaning is related to digestion. Peptic ulcer occurs in the part of the gastrointestinal track which is exposed to gastric acid and pepsin (i.e) the stomach and duodenum. The extract of Tephrosia purpurea flowers against viruses and is very good antibacterial against Gram +ve and Gram -ve strain. The Plant extract was prepared and the phytochemical analysis was performed. The extract was administered with animals. The drug were administered orally once daily for 2 days and 45 min prior to pyloric ligation. The animals are sacrificed after four hours of pylorus ligation. The result indicates that, Flavonoids and Tannins have shown to be present in the TPAL treated groups. Since flavanoids antagonize aggressive factor which play a decisive role in the pathogenesis of gastric lesion and also enhance defence factor to protect the gastric mucosa from injury. Flavanoids diminish histamine secretion from mast cell by inhibition of histidine decarboxylase and stimulate PG biosynthesis. So the antiulcer activity of TPAL may be attributed to its flavonoid content. The study concluded that TPAL has an anti ulcer activity which may be due to protection and the strengthening of the mucosal defensive factor like mucus, bicarbonate, prostaglandin.

“…It was found that the extract decreased colonic malondialdehyde (MDA) and increased colonic glutathione (GSH), glutathione peroxidase (GPx), and catalase (CAT) activities (75) . The anti-inflammatory effect of leaf ethanolic extract was also confirmed by its ability to decrease carrageenan-induced edema in rat paws by about 47.16% (76) . One of the most interesting outcomes of the anti-inflammatory properties of A. squamosa is the anti-psoriatic effect of seed oil.…”
