A dimeric triterpene-glycoside from Rubus coreanus

A dimer of glucosyl esters of A-ring oxygenated 19α-hydroxyursolic acids was isolated from leaves of Rubus coreanus together with the monomers of the related glucosyl esters. The structure of this compound, named coreanoside F1, was elucidated by chemical and spectroscopic methods. The significance...

Zusammenfassung:	A dimer of glucosyl esters of A-ring oxygenated 19α-hydroxyursolic acids was isolated from leaves of Rubus coreanus together with the monomers of the related glucosyl esters. The structure of this compound, named coreanoside F1, was elucidated by chemical and spectroscopic methods. The significance of coreanoside F1 in the identification of the source plants of an oriental traditional medicine ‘Bog-bun-ja’ (= Fu-pen-zi) is discussed.
