By means of preparative HPTLC and column chromatography over silica gel and Sephadex LH-20, ten sesquiterpenes were isolated and purified from the whole plants of Solanum septemlobum Bunge. Based on the physico-chemical properties and spectral data, their structures were elucidated and identified as lyratol D(1), solajiangxin B(2), 1 ,2-dehydrocyperone(3), solanerianone A (4), dehydrocarissone(5), ligucyperonol(6), nardoeudesmol A(7), solajiangxin F(8), and lyratol B(9), solajiangxin D(10). For the first time, compounds 1-10 were isolated from Solanum septemlobum, and compounds 5-7 were obtained from the genus Solanum.
