A new seco-iridoid glycoside from the aerial part of Fraxinus raibocarpa

摘要

The new seco-iridoid glycoside raibocarpaoside was isolated from the aerial part of Fraxinus raibocarpa Rgl. (Oleaceae). The structure 1-O-β-D- glucopyranosyl-4,6-dicarboxymethyl-8-methyl-7,8-seco-cyclopent-8-en[c]-1, 9-dihydropyran was established based on spectralCharacteristics andChemical transformations.
