Chemical investigation on the rhizome of Souliea vaginata resulted in isolation two new cycloartane triterpene glycosides and a alkaloid, soulieosides D E, soulieotine (1⎯3), their structures were elucidated basis extensive NMR spectral experiments chemical methods as (20S * ,22R ,23S ,24R )-16β:23;22:25-diepoxy-3β,24-dihydroxy-23-methoxy-9,19cyclolanostane-3-O-β-D-(4-acetyl)xylopyranoside (1), )-16β:23;22:25-diepoxy-3β,23,24-trihydroxy-9,19-cyclolanostane-3-O-β-D-(3-acet yl)xylopyranoside (2), E-3-
