Seven new steroidal compounds were isolated from the fresh bulbs of Camassia cusickii S. WATS. Their structures were detemined by spectroscopic analysis and hydrolysis to be (25R)-5α-spirostan-3β, 6α-diol (chlorogenin) 6-O-β-D-xylopyranosyl-(1→3)-β-D-glucopyranoside (1), chlorogenin 6-O-β-D-xylopyranosyl-(1→2)-O-[β-D-glucopyranosyl-(1→3)]-β-D-glucopyranoside (2), chlorogenin 6-O-β-D-glucopyranosyl-(1→2)-O-[β-D-xylopyranosyl-(1→3)]-β-D-glucopyranoside (3), chlorogenin 6-O-β-D-fucopyranosyl-(1→2)-O-[β-D-glucopyranosyl-(1→3)]-β-D-glucopyranoside(4), 22-O-methyl-26-O-β-D-glucopyranosyl-(25R)-5α-furostan-3β, 6α, 22ξ-triol 6-O-β-D-glucopyranosyl-(1→3)-β-D-glucopyranoside (5), 22-O-methyl-26-O-β-D-glucopyranosyl-(25R)-5α-furostan-3β, 6α, 22ξ-tiol 6-O-β-D-glucopyranosyl-(1→2)-O-[β-D-glucopyranosyl-(1→3)]-β-D-glucopyranoside (6) and 3β, 7β, 16β-trihydroxycholest-5en-23-one 3,16-bis-O-β-D-glucopyranoside (camassioside)(7).
