(Tiliaceae)" - Chemical and Pharmaceutical Bulletin 45 (1997) 464-469
  

  Three new ionone glucosides named corchoionosides A, B, and C were isolated from the leaves of Corhorus olitorius, commonly called "moroheiya" in Japanese, together with seven known compounds, an ionone glucoside (6S, 9R)-roseoside, a monoterpene glucoside betulalbuside A, two flavonol glucosides astragalin and isoquercitrin, two coumarin glucosides scopolin and cichoriine, and chlorogenic acid. The absolute stereostructures of corchoionosides A, B, and C were determined by chemical and physicochemical evidence, which included the result of application of a modified Mosher's method, the CD helicity rule, and chemical correlation with (6S, 9R)-roseoside. Corchoionosides A and B and (6S, 9R)-roseoside were found to inhibit the histamine release from rat peritoneal exudate cells induced by antigen-antibody reaction.

  Repeated fractionation of an aqueous ethanol extract of the whole herb of Wahlenbergia marginata afforded six ionone-related and five phenylpropanoid-derived glycosides. The structures of the five new compounds were established by spectroscopic and chemical methods as 3,5,5-trimethyl-4- (2'-β-D-glucopyranosyloxy)ethyl-cyclohexa-2-en-1-one, demethyl syringin, wahlenosides A, B and C, respectively. All constituents were not active against the human pathogenic fungi Candida albican, Trichoderma viride and Aspergillus flavus.
