A new furanolabdane diterpene glycoside from Phlomis younghusbandii Mukerjee / 药学学报

In order to find the compound basis of Phlomis younghusbandii Mukerjee that related to pharmacodynamic action, various chromatographic techniques were used to separate and purify the constituents of this plant, and physicochemical and spectral data were used to identify the structures of obtained compounds. A new furanolabdane diterpene glycoside, named as phlomisoside F, was isolated and identified, which was 15,16-epoxy-8(9),13(16), 14-labdatrien-7-ketone-19-oic acid-beta-D-glucopyranosyl ester.
