DC.Its structure was elucidated on the basis of spectral analysis.展开更多
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 s...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.展开更多
