Scopoletin and β-sitosterol glucoside from roots of Ipomoea digitata

Abstract

Plants are ancient source of medicine due to presence of bioactive molecules of various compounds in its different parts. Two compounds were isolated from ethanol extract of the roots of Ipomoea digitata. The compounds are Scopoletin (7-hydroxy-6-methoxycoumarin) and I²-sitosterol glucoside. The structures were elucidated by spectroscopic analysis (1H NMR & 13C NMR). Though the compounds are known natural products, scopoletin is the first report of its occurrence from the plant Ipomoea digitata. The compound scopoletin is very much important for its medicinal value.
