Phytochemical investigation of the ethanol extract obtained from the aerial parts of the Euphorbia altotibetic PAULS. grown in China resulted in the isolation of three new cholestane-type and three new ergostane-type steroids (cholest-5-en-2β, 4β-diol; cholest-5-en-1β, 4β-diol; cholest-5-en-1α, 3β, 4 α -triol; (22E)-ergosta-7,9,22-trien- 3β-ol β-D-glucoside; 5α-methoxy-(22E)-ergosta-7,9,22-trien-3β-ol β-D-glucoside; 6β- methoxy-(22E)-ergosta-7,9,22-trien-3β-ol β-D-glucoside), along with seven known compounds. Their structures were established by extensive one- and two-dimensional NMR spectroscopy, as well as other spectrum and chemical analysis. The isolated new steroids exhibited potent anti-tumor activity against the HeLa cell and Hep-G2 cell with the 50% inhibiting concentration values ranging from 1.9 to 9.2 μg/mL.
