The constituents of the fresh whole plants of Heloniopsis orientalis (THUNB.) C. TANAKA (Liliaceae) were investigated and five steroidal components were obtained. Their chemical structures were characterized as dioscin (1), pennogenin3-O-β-chacotrioside(T-c)(2), pregnadienolone 3-O-β-chacotrioside(P-d)(3), 26-O-β-D-glucopyranosyl17-dehydrokryptoenin 3-O-β-chacotrioside (4) and 12-O-β-D-galactopyranosyl helonigenin 3-O-β-D-allomethylopyranosyl-(1→5)-β-D-apiofuranoside (5).
