9,10-dihydropenanthrene derivate from Epimedium koreanum

A new 9,10-dihydrophenanthrene derivative named epimedoicarisoside A was isolated from the aerial parts of Epimedium koreanum along with ten known flavonoids. The structure of this compound was determined on the basis of spectral analysis (FAB-Mass spectrometry, 1H-1H COSY, 1H-13C COSY, DEPT, and 1H...

Description
Summary:A new 9,10-dihydrophenanthrene derivative named epimedoicarisoside A was isolated from the aerial parts of Epimedium koreanum along with ten known flavonoids. The structure of this compound was determined on the basis of spectral analysis (FAB-Mass spectrometry, 1H-1H COSY, 1H-13C COSY, DEPT, and 1H-13C long range COSY, etc.) as 2-hydroxy-3,4,6,7-tetramethoxy-9,10-dihydrophenanthrene 2-O-beta-D-glucopyranoside. The known compounds were identified as icariin, epimedoside C, icarisid 1, baohuoside 1, diphylloside A, baohuoside II, 2''-O-rhamnosylicarisid II, sagittatoside A. hyperoside and icaritin-3-O-rhamnopyranoside.
