A new furostanol saponin, sisalasaponin C (1), and a new spirostanol saponin, sisalasaponin D (2), were isolated from the fresh leaves of Agave sisalana, along with three other known steroidal saponins and two stilbenes. Their structures were identified as (3b,5a,6a,22a,25R)-3,26-bis[(b-d-glucopyran

## Abstract The detailed NMR studies and full assignments of the ^1^H and ^13^C spectral data for two new furostanol saponins isolated from __Agave sisalana__ leaves are described. Their structures were established using a combination of 1D and 2D NMR techniques including ^1^H, ^13^C, ^1^Hο£Ώ^1^H COS
