A new flavonoid glucoside with a known one was isolated from the leaves of Cassia *** on the spectral analysis,including MS,H-NMR,C-NMR, DEPT,H-HCOSY,HMQC,HMBC and NOSEY,their chemical structures were determined as kaempferol-3-O[（6′′′-O-trans-sinnapoyl）-β-D-glucopyranosyl（1→6）]-β-D-glucopyranoside 1 and apigenin-6,8-di-C-glycoside 2.
A new anthraquinone glycoside 1,along with a known anthraquinone glycoside aurantio-obtusin-6-O-β-D-glucopyranoside 2,were isolated from the seeds of Cassia *** the basis of spectral and chemical evidences,the struct...

A new anthraquinone glycoside 1,along with a known anthraquinone glycoside aurantio-obtusin-6-O-β-D-glucopyranoside 2,were isolated from the seeds of Cassia *** the basis of spectral and chemical evidences,the structure of 1 was established as 1-demethylaurantio-obtusin-2-O-β-***,the C NMR of 2 was assigned totally and correctly for the first time based on the 2D NMR.
