Steroid sponins and flavonoids of leaves of Phoenix rupicola T. ANDERSON, P. loureirii KUNTH, P. reclinata N. J. JACQUIN, and Arecastrum romanzoffianum BECCARI have been investigated. Tricin 7-O, β-D-glucopyranoside (I), vitexin (II), methyl proto-Pb (VII), methyl proto-taccaoside (26- O, β-D-glucopyranosyl (25R)-22-O-methyl-furost-5-en-3β,26-diol 3-O-[α-L-rhamnopyranosyl-(1→2)][α-L-rhamnopyranosyl-(1→3)]-β-D-glucopyranoside, VI), and methyl proto-rupicolaside (26-O, β-D-glucopyranosyl (25R)-22-O-methy-furost-5-en-3β,26-diol 3-O-[β-D-glucopyranosyl-(1→2)-α-L-rhamnopyranosyl-(1→4)-α-L-rhamnopyranosyl-(1→4)][α-L-rhamnopyranosyl-(1→2)]-β-D-glucopyranoside, VIII) from P. rupicola, II, glucoluteolin (III), orientin (IV), isoorientin (V), VII, VIII, and methyl proto-loureiroside (26-O-β-D-glucopyranosyl (25R)-22-O-methyl-furost-5-en-3β,26-diol 3-O-[β-D-glucopyranosyl-(1→5)-α-L-arabinofuranosyl-(1→4)][α-L-rhamnopyranosyl-(1→2)]-β-D-glucopyranoside, IX) from P.loureirii, VII, VIII and methyl proto-reclinatoside (26-O-β-D-glucopyranosyl (25R)-22-O-methyl-furost-5-en-3β,26-diol 3-O-[α-L-rhamnopyranosyl-(1→5)-α-L-arabinofuranosyl-(1→4)][α-L-rhamnopyranosyl(1→2)]-β-D-glucopyranoside, X) from P. reclinata, III and VII from A. romanzoffianum were isolated are identified. VI, VIII, IX and X were the first isolated and characterized from natural sources.
