Abstract

Two new steroidal saponins, 8 and 10, along with 7 known steroidal sapogenins and saponins (17) and a furostanol saponin (9) were isolated from Agave sisalana Perrine ex Engelm. The structures of these two new compounds were identified and characterized by 1D and 2D NMR spectroscopy and mass spectrometry. In addition, acid hydrolysis and GC‐FID were used to confirm the sugar moieties of 8 and 10. The cytotoxic effects of 110 on MCF-7, NCI-H460, and SF-268 cancer cells were evaluated, and among them, compound 10 proved to be the most cytotoxic with IC50 values of 1.2, 3.8, and 1.5 µM, respectively.
