| Abstract: | OBJECTIVE: To study the chemical Constituents in the root of Rheum glabricaule. METHODS: Compounds were isolated by various column chromatographies with sillica gel. Their structures were identified by spectral analysis (MS, 1HNMR, 13 CNMR) and chemical evidences. RESULTS: Seven compounds were isolated from this plant, including n-hexacosnic acid (I), palmitic acid (II), daucosterol (III), chrysophanol-8-Me ether (IV), citreorosein (V), chrysophanol 8-O-beta-D-glucopyranoside (VI) and 2,5-dimethyl-7-methoxychromone (VII). CONCLUSION: All above compounds are obtained from this plant for the first time. |
