Abstract

Two new furostanol saponins 12 and a new spirostanol saponin 3 were isolated together with two known furostanol saponins 45 from the roots and rhizomes of Tupistra chinensis. Their structures were characterized as 1β,2β,3β,4β,5β,26-hexahydroxyfurost-20(22), 25(27)-dien-5,26-O-β-d-glucopyranoside (1), 1β,2β,3β,4β,5β,6β,7α,23ξ,26-nona-hydroxyfurost- 20(22),25(27)-dien-26-O-β-d-glucopyranoside (2), (20S,22R)-spirost-25 (27)-en-1β,3β,5β- trihydroxy-1-O-β-d-xyloside (3), tupisteroide B (4) and 5β-furost-Δ25(27)-en-1β,2β,3β,4β,5β,7α, 22ξ,26-octahydroxy-6-one-26-O-β-d-glucopyranoside (5), respectively, by extensive use of spectroscopic techniques and chemical evidence. Additionally, the in vitro cytotoxic activity of 14 was evaluated on human A549 and H1299 tumor cell lines, and compound 3 exhibited cytotoxicity against A549 cells (IC50 86.63 ± 2.33 μmol·L−1) and H1299 cells (IC50 88.21 ± 1.34 μmol·L−1).
