Abstract:
Objective To investigate the chemical constituents from the roots of Angelica dahurica. Methods The chemical constituents were isolated and purified by AB-8 macroporous adsorption resin and Sephadex LH-20 column as well as semi-preparative reversed phase HPLC. The chemical structures were identified by spectral data. Results Ten compounds were isolated and identified as xanthoarnol-3'-O-β-D-glucopyranoside (1), angedahuricoside A (2), angedahuricoside B (3), isofraxidin-7-O-β-D-glucopyranoside (4), fraxidin-8-O-β-D-glucopyranoside (5), (-)-marmesinin (6), (2'S,3'R)-3'-hydroxymarmesinin (7), hyuganoside V (8), daucosterol (9), and sucrose (10). Conclusion Compounds 1–3 are new ones and 4–6 and 8 are obtained from title plant for the first time.
