The constituents of the leaves of Sabal causiarum BECC. have been investigated. Vitexin, methyl proto-deltonin, methyl proto-causiaroside I(=26-O-β-D-glucopyranosyl 22-O-methyl-25(R)-furost-5-en-3β, 26-diol 3-O-[α-L-rhamnopyranosyl(1→4)-β-D-glucopyranosyl(1→4)][α-L-rhamnopyranosyl(1→2)]-β-D-glucopyranoside) and causiaroside II(=3β, 16β-dihydroxypregn-5-en-20-one 3-O-[α-L-rhamnopyranosyl(1→4)-β-D-glucopyranosy(1→4)][α-L-rhamnopyranosyl(1→2)]-β-D-glucopyranosyl 16-O-[δ-(β-D-glucopyranosyloxy)-γ-methyl]-valerate) were isolated and identified. This is the first isolation and characterization of the latter two compounds from a natural source, and these results are interesting from the standpoint of the biogenesis of the steroidal glycosides of the Palmae plants.
