| Abstract: | Nine compounds were isolated from Gynura segetum for the first time. Their structures were identified to be stigmasterol (1), isoarborinol (2), arborinol (3), zhebeiresinol (4), lumichrome (5), (2S, 3S, 4R, 8E)-2-(2R)-2-hydroxypalmitoylamino]-8-octadecene-1, 3, 4-triol (6), syringic acid (7), vanillic acid (8), trans-p-hydroxycinnamic acid (9) on the basis of mass and NMR spectra. Compound 5 has not been recorded before in plants, but it is widely distributed in different fungi and may provide a worthy systematic basis for the genus. |
