Chemical examination of the fresh rhizomes of Tupistra wattii HOOK. f. led to the isolation of three new steroidal saponins, wattoside G (1), H (2), and I (3), together with one known steroidal saponin, (25S)-1β, 3β, 4β-trihydroxyspirotan-5β-yl-0-β-D-glucopyranoside (4). The structures of 1-3 were established to be (25R)-1β, 2β, 3β, 5β-tetrahydroxyspirostan-4β-yl-0-β-D-xylopyranoside (1), (24S, 25S)-24-[(β-D-glucopyranosyl)oxy]-1β, 2β, 3β, 4β, 5β, 7β-hexahydroxyspirostan-6-one (2), and (24S, 25S)-1β, 3β-dihydroxy-5β-spirostan-24-yl-0-β-D-glucopyranosyl-(1→6)-β-D-glucopyranoside (3) on the basis of detailed analyses of physical, chemical, and spectral data. The isolated compounds were evaluated for cytotoxic activity against the cancer cell line K562 in vitro.
