| Abstract: | OBJECTIVE To study the chemical constituents in the root of Rheum glabricaule.METHODS Compounds were isolated by various column chromatographies with silica gel.Their structures were elucidated by spectral analysis(MS,1H-NMR,13C-NMR) and chemical evidence.RESULTS Five compounds were isolated from this plant,and identified as dibutyl phthalate(Ⅰ),emodin-8-O-β-D-glucopyranoside(Ⅱ),aloe-emodin-3-(hydroxymethyl)-O-β-D-glucopyranoside(Ⅲ),β-sitosterol-3-O-β-D-(6′-O-acyl)-glucopyranoside(Ⅳ) and kaempferol(Ⅴ),respectively.CONCLUSION All above compounds are obtained from this plant for the first time. |
