Protective effect of Echinops galalensis against CCl4-induced injury on the human hepatoma cell line (Huh7)

► Phytochemical investigation of the flowering aerial parts of Echinops galalensis. ► A new triterpene, 3β-acetoxy-taraxast-12, 20(30)-diene-11α,21α-diol, was isolated. ► Isolated compounds were tested for their protective effect on human hepatoma cells. ► The protective effect was suggested to be mediated by antioxidant activity.
