A new flavonoid glucoside with a known one was isolated from the leaves of cassia angustifolia. Based on the spectral analysis, including MS, ^1H NMR, ^13C NMR, DEPT, ^1H-1HCOSY, HMQC, HMBC and NOSEY, their chemical structures were determined as kaempferol-3-O-[（6＇＇＇-O-trans-sinnapoyt）-β-D-glucopyranosyl （1 → 6）]-β-D-glucopyranoside 1 and apigenin-6,8-di-C-glycoside 2.

关键词： cassia angustifolia Flavonol glucoside Kaempferol-3-O-[ (6'''-O-trans-sinnapoyl)-β-D-glucopyranosyl-(1→6)]-β-D-glucopyranoside

Two new glycosides were isolated and characterized by spectral analysis from the seeds of cassia obtusifolia and the leaves of cassia angustifolia. The structure was elucidated as 1-hydroxyl-2-acetyl-3,8-dimethoxynaphthalene-6-O-β-D-apiofuranosyl- （1→2）-β-D-glucopyranoside and 2-acetyl-3-methyl-8-methoxyl-1,4-naphthoquinone-6-O-β-D-glucopyranoside.
