[Studies on the chemical constituents of the roots of Anemone altaica].

OBJECTIVE: To investigate the chemical constituents of the roots of Anemone altaica Fisch. ex C. A. May. METHODS: The constituents of n-BuOH-soluble portion were isolated and purified by means of chromatography. Compounds were identified by their physical characteristics and spectral features. RESULTS: Six compounds were isolated and identified as cimigenol-3-O-beta-D-xylopyranoside (1), cimigenol-3-O-beta-D-xylopyranol (1 -->3)-beta-D-xylopyranoside (2), isolariciresinol-9-O-beta-D-glucopyranoside (3), adenosine (4), uridine (5) and methyl-beta-D-glucopyranoside (6). CONCLUSION: All compounds are isolated from this genus for the first time.
