New Sucrose Derivatives from the Bark of Securidaca longipedunculata

Two new bitter principles were isolated from the bark of Securidaca longipedunculata (Polygalaceae) and identified as beta-D-(3,4-disinapoyl)fructofuranosyl-alpha-D-(6-sinapoyl)g lucopyranoside and beta-D-(3-sinapoyl)fructofuranosyl-alpha-D-(6-sinapoyl)gluco pyranoside. The structures were elucidate...

Zusammenfassung:	Two new bitter principles were isolated from the bark of Securidaca longipedunculata (Polygalaceae) and identified as beta-D-(3,4-disinapoyl)fructofuranosyl-alpha-D-(6-sinapoyl)g lucopyranoside and beta-D-(3-sinapoyl)fructofuranosyl-alpha-D-(6-sinapoyl)gluco pyranoside. The structures were elucidated by a combination of 1H nmr (1D, 2D COSY, 2D HOHAHA), 13C-nmr, and fabms spectra.
