Studies on the Constituents of Palmae Plants. III. : The Constituents of Chamaerops humilis L. and Trachycarpus wagnerianus BECC.[Reference: WebLink]

METHODS AND RESULTS:
We isolated and identified methyl proto-dioscin and pseudoproto-dioscin from the stems, Pb, Tg, methyl proto-Pb and Pseudoproto Pb from the underground parts, and glucoluteolin, scolymoside, methyl proto-Pb and Pseudoproto Pb from the leaves of T. wagnerianus BECC.
CONCLUSIONS:
This is the first report of the isolation of tricin 7-O-β-rutinoside, Tg and pseudodiosgenin oligosides from Palmae plants, and also the first discovery of pseudosteroidal saponin from natural sources.
