Objective: To study the chemical composition of ramie root. Methods: Various chromatographic techniques were used for the separation, and the structures were identified based on the spectral data and chemical methods of the compounds. RESULTS: Eight compounds were isolated and identified as emodin (1), emodin-8-O-β-D-glucopyranoside (2), physcion (3), resveratrol (4), catechin (5), epicatechin (6), KNO3 (7) and β-sitosterol (8). Conclusion: Compounds 3 ~ 7 were isolated from ramie root for the first time.
