- 論文の詳細を見る
Constituents of Leucothoe Keiskei, poriolide (1) and isoporiolide (2) have a novel structure of the macrocyclic biphenyl-type flavonoid glycosides. Results of the spectroscopic analysis and the chemical degradation of these compounds are discussed. The structure of isoporiolide, an isomer of poriolide, was derived from a comparison of the degradation products of poriolide, isoporiolide and their derivatives. On hydrolysis with barium hydroxide, both hexamethylethers (5 and 17) of poriolide and isoporiolide gave the identical propiophenone glycoside (12a), but the isoporiolide hexamethylether yielded an isomer (18a) of the carboxylic acid (13a) obtained from the poriolide hexamethylether.
