Crabbogenin, 1β-hydroxycrabbogenin, strictagenin and pompeygenin, four new steroidal sapogenins from cordyline stricta leaves

From the leaves of Cordyline stricia Endl. four new steroidal sapogenins crabbogenin {5α-spirost-25(27)-en-3α-ol}, 1β-hydroxycrabbogenin, strictagenin {(20S, 22S, 25S)-5α-furostan-22, 25-epoxy-1β, 3α, 26-triol} and pompeygenin {(25S)-5α-spirostane-1β, 3α-25-triol} have been isolated and their structures determined by chemical and spectroscopic methods
