Solanum xanthocarpum is a spiny diffuse herb and used in medicine in various forms, such as decoction, electuary, ghrita, etc. Its roots are one of the constituents of well known Ayurvedic preparation “Dasmula Ashva”. Phytochemical investigation of the ethyl acetate extract of the roots of Solanum xanthocarpum growing in Ramnagar region led to the isolation of caffeic acid and oleanolic acid using different chromatographic methods (i.e. paper, thin layer, and column chromatography). The structure of these compounds was determined by extensive IR, UV, and NMR spectroscopy.
