Triterpenes of Centaurea ptosimopappoides
Phytochemistry, 1997 The roots of Centaurea ptosimopappoides afforded two new triterpenes; a new hopane derivative, 17β,21β-epoxy-16α-ethoxyhopan-3β-ol and a new baccharane type triterpene, 3β-acetoxy-17,24-dioxobaccharane. The known compounds, 17β,21β-epoxyhopan-3β-ol, 3β-acetoxyhop-17(21)-ene and 3β-acetoxy-erythrodiol were also isolated.
