Spirocaracolitone triterpenoids from the bark of Ruptiliocarpon caracolito.
Six new triterpenoids named spirocarcolitones (G-L), which belong to a novel class of CD-spiro triterpenoids, were isolated from the dichloromethane-soluble fraction of the bark of Ruptiliocarpon caracolito. The structures of these natural products were established using mainly 1D and 2D NMR spectroscopy. One known CD-spiro triterpenoid and canophyllol were also isolated from the same source.
