Sterols from four species of liliaceae

Fractionation of the sterol mixture from Tristagma uniflorum, Nothoscordum gramineum var. philippianum, Nothoscordum inodorum, and Nothoscordum montevidense were achieved by means of preparative TLC. Analysis of the fractions by GC and GC-MS allowed the identification of Δ0, Δ5, and Δ7 sterols. The...

Sumario:Fractionation of the sterol mixture from Tristagma uniflorum, Nothoscordum gramineum var. philippianum, Nothoscordum inodorum, and Nothoscordum montevidense were achieved by means of preparative TLC. Analysis of the fractions by GC and GC-MS allowed the identification of Δ0, Δ5, and Δ7 sterols. The unusually high proportion of cholestan-3β-ol seems to be biogenetically related to the C27 steroidal sapogenins contained in those plants. © 1987.
