New Sucrose Derivatives from the Bark of Securidaca longipedunculata

Journal of Natural Products, 1993
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),

A new sterol glycoside from Securidaca inappendiculata

Journal of Asian Natural Products Research, 2005
From the roots of Securidaca inappendiculata, one new sterol glycoside securisteroside (1) has been isolated, along with two known sterols, spinasterol (2) and 3-O-beta-D-glucopyranosyl-spinasterol (3). The new sterol was characterized by chemical and spectrometric methods, including EIMS, FABMS and one- and two-dimensional NMR experiments.
