[Abstract] Ten compounds were isolated from the aerial part of Solanum rostratum by means of various chromatographic techniques such as silica gel，Sephadex LH-20，ODS and preparative HPLC. Their structures were identified as dioscin(1)，hypoglaucin H(2)，hyperin(3)，isoquercitrin(4)， isorhamnetin-3-O-β-D-galactopyranoside(5)，kaempferol-3-O-β-D-glucoside(6)，smilaxchinoside A(7)，26-O-β-D-glucopyranosyl-3β，20α，26-triol-25(R)-Δ5，22-dienofurostan-3-O-α-L-rhamnopyranosyl(1→2)-[α-L-rhamnopyranosyl(1→4)]-β-D-glucopyranoside(8)，β-sitosterol(9)，and daucosterol(10)，on the basis of physicochemical properties and spectroscopic data analysis. Among them ，compounds 7 and 8 were isolated from the genus Solanum for the first time，and the remaining compounds were obtained from this plant for the first time.
