Abstract | ETHNOPHARMACOLOGICAL RELEVANCE: Solanum melongena L. (eggplant) is used for treatment of rheumatism, beriberi, itching, toothache, bleeding, asthma, bronchitis, cholera, neuralgia and hemorrhoids in traditional medicine (Turkish, Chinese, and Indian). Hemorrhoids from these diseases, are common illness in all over the world, which are treated with various approaches including ethnobotanicals. AIM OF THE STUDY: This study aimed to evaluate the anti-hemorrhoidal activity of eggplant, an edible plant, which is commonly utilized around the world. MATERIALS & METHODS: In vivo anti-hemorrhoidal activity of the methanolic extract prepared from eggplant was evaluated by experimental hemorrhoid model, subsequently histological and biochemical analysis. Hemorrhoid, which was induced by applying croton oil to the anal area of the rats. Furthermore, the extract was screened for anti-inflammatory activity which is based on the inhibition of acetic acid-induced increase in capillary permeability. The healing potential was comparatively assessed with a reference Pilex® tablet and cream. Phytochemical analysis performed by HPLC. The amount of the major phenolic compound ( chlorogenic acid) in extract was found by using HPLC method. RESULTS: Histological and biochemical analysis demonstrated that eggplant extract is highly effective against hemorrhoid in comparison to the controls and the commercial preparation. In addition, the methanolic extract demonstrated significant inhibitory effect on acetic acid-induced increase in capillary permeability. The phytochemical studies identified major compound as chlorogenic acid (2.86%) by liquid chromatography. CONCLUSION: The eggplant calyxes, not edible, are easy to reach, by products/vast from the food sources. This is the first scientific evidence revealing that the eggplant extract has significant anti-hemorrhoidal and anti-inflammatory activity.
