Two new steroidal saponins (1 and 2), along with four known ones (3???6) were obtained from the roots and rhizomes of Maianthemum henryi, their structures were determined to be spirost-5, 25(27)-diene-l?, 3?-diol 1-O-?-L-rhamnopyranosyl-(1 ? 2)-4-O-acetyl-?-D-fucopyranoside (1), (23S, 24S)-spirost-5, 25(27)-diene-l?, 3?, 23, 24-tetrol 1-O-?-L-rhamnopyranosyl-(1 ? 2)-4-O-acetyl-?-D-fucopyranoside (2), spirost-5, 25(27)-diene-l?, 3?-diol 1-O-?-L-rhamnopyranosyl-(1 ? 2)-?-D-fucopyranoside (3), spirost-5, 25(27)-diene-l?, 3?-diol 1-O-?-L-rhamnopyranosyl-(1 ? 2)-?-D-xylopyranoside (4), Henryioside A (5)?Henryioside B (6), by physicochemical properties and spectroscopic methods. In addition, their cytotoxic activity against human HepG2 tumor cells was evaluated by MTT method and all of the compounds exhibited cytotoxicity with the cells.
