  Structures of eremophilane-type sesquiterpene glucosides, alticolosides A–G, from the Far Eastern endemic Ligularia alticola Worosch

  摘要：

  Seven eremophilane-type sesquiterpene glucosides, alticolosides A-G, have been isolated from aerial parts of the endemic Far Eastern species Ligularia alticola Worosch. (Family Asteraceae) along with two known compounds, monoterpenoid glycoside (4S)-alpha-terpineol 8-O-beta-D-glucopyranoside and norditerpenoid glycoside 7(8)-dihydro-beta-ionone 3-O-beta-D-glucopyranoside. Alticoloside D was identified with the earlier known 8-O-(beta-D-glucopyranosyl)-2-oxo-eremophila-1(10),8,11-triene, but the stereostructure of the latter was revised on the basis of ROESY and CD data. All the glycosides are derivatives of new eremophilane-type aglycones, differing from known eremophilanes in details of planar and/or stereo structures except for the aglycone of alticoloside E.

  Medicinal Foodstuffs. XXXII. Novel Sesquiterpene Glycoside Sulfate, Fukinoside A, with Antiallergic Activity from Japanese Butterbur (Petasites japonicus)

  摘要：

  Novel sesquiterpene glycoside sulfate, fukinoside A, was isolated as the potassium salt from the aerial parts of Petasites japonicus. The absolute sterostructure of fukinoside A was elucidated on the basis of chemical and physicochemical evidence. In addition, fukinoside A was found to inhibit release of beta-hexosaminidase, as a marker of antigen-induced degranulation, in RBL-2H3 cells.
