Steroid saponins and flavonoids of the leaves of Phoenix canariensis hort. ex CHABAUD, P. humilis ROYLE var. hanceana BECC., P. dactylifera L., and Licuala spinosa WURMB. have been investigated. Tricin 7-O-β-D-glucopyranoside (1), isorhamnetin 3-O-β-D-glucopyranoside (2), isoquercitrin (3), isorhamnetin 3-O-β-rutinoside (4), rutin (5), and methyl (25S)-proto-Pb (6) from P. canariensis, 1, 6, glucoluteolin (7), tricin 7-O-α-L-rhamnopyranosyl(1→2)-β-D-glucopyranoside (8), and methyl (25S)-proto-loureiroside (9) from P. humilis var. hanceana, 1, 2, 8, methyl proto-prosapogenin A of dioscin (10), methyl proto-reclinatoside (11) and methyl proto-Pb (12) from P. dactylifera, and vitexin (13) and methyl (25S)-proto-dioscin (14) from Licuala spinosa have been isolated and identified.
