Bioactive constituents from Chinese natural medicines. XXVIII. Chemical structures of acyclic alcohol glycosides from the roots of Rhodiola crenulata.

摘要

Five new glycosides, creosides I, II, III, IV, and V, were isolated from the methanolic extract of the roots of Rhodiola crenulata, together with 21 known compounds. The chemical structures of new constituents were elucidated on the basis of chemical and physicochemical evidence.
