A series of five new polyhydroxylated steroidal saponins, named recurvosides A - E, were isolated from the stems of Nolina recurvata (Agavaceae). Their structures were determined through detailed interpretation of various spectra, including two-dimensional (2D) NMR, and by acid-catalized hydrolysis....
