TRITERPENE GLYCOSIDES OF Climacoptera transoxana. III. THE STRUCTURES OF COPTEROSIDES E AND F

Article abstract of DOI:10.1007/BF00576083

New triterpene glycosides have been isolated from the epigeal part of Climacoptera transoxana (Iljin) Botsch. - copterosides E and F.According to chemical transformations and physicochemical characteristics, copteroside E has the structure of oleanolic acid 28-O-β-D-glucopyranoside 3-O-<2)>-4)>-β-D-glucuronopyranoside> and copteroside F that of hederagenin 28-O-β-D-glucopyranoside 3-O-<2)>-4)>-β-D-glucopyranoside>.
