Studies on the Constituents of Palmae Plants. VI. Steroid Saponins and Flavonoids of Leaves of Phoenix canariensis hort. ex CHABAUD, P. humilis ROYLE var. hanceana BECC., P. dactylifera L., and Licuala spinosa WURMB.

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.
