Objective To explore the chemical constituents of traditional She medicine Rubi Radix et Rhizoma (the roots and rhizomes of Rubus chingii in family Rosaceae). Methods The compounds were isolated and purified by various column chromatography and the structures were identified by physicochemical constant determination and spectral analysis. Results Nine compounds were isolated and identified as β-sitosterol (1), daucosterol (2), euscaphic acid (3), 11α-euscaphic acid (4), tormentic acid (5), ellagic acid (6), gallic acid (7), ursolic acid (8), and oleanolic acid (9) from 95% ethanol extract of Rubi Radix et Rhizoma. Conclusion All the nine compounds are isolated from Rubi Radix et Rhizoma for the first time and the compound 4 is first isolated from R. chingii.
