Abstract

Three new spirostanol glycosides, trilliumosides K-M (1-3), one new sesquiterpenoid glycoside, tritschsesuquiside A (4), along with three known analogues (5-7) were obtained from the rhizomes of Trillium tschonoskii. The structures of new glycosides were elucidated by spectroscopic analyses (HRMS and NMR) and chemical methods. Glycosides 5-7 displayed cytotoxicities against five human cancer cell lines with IC50 values ranging from 10.5 ± 1.0 to 1.0 ± 0.2 μM, with 7 being the most cytotoxic compound with IC50 values of 1.0 ± 0.2, 2.2 ± 1.2, and 3.4 ± 0.4 μM against Huh7, CCRF-CEM, and HeLa cell lines, respectively. The flow cytometric results revealed that both 5 and 6 could induce apoptosis of HCT116 and Huh7 cells.
