Object To study the chemical constituents from the root of Patrinia scabra Bge. Methods The constituents were separated and purified by silica gel column chromatography. Their structures were elucidated by physicochemical properties and spectral data (IR, MS, 1HNMR, 13CNMR, 2DNMR). Results Five compounds were isolated from the root of P. scabra. They were identified as curvularin (Ⅰ), kaempferol (Ⅱ), 5, 7-dihydroxyflavone (Ⅲ), β-sitosterol (Ⅳ), β-sitosterol-3-O-β-D-glucopyranoside (Ⅴ). Conclusion All the compounds are obtained from this plant for the first time. Among them, compound Ⅰ has cytotoxic effect.
