ergostanol glycosides (2 and 3), and a new furostanol glycoside (4), along with nine known steroidal derivatives (5–12) were isolated from the seeds of Withania somnifera. The structures of the new compounds were determined using spectroscopic analysis and hydrolysis. The cytotoxic activities of the isolated compounds were evaluated against Ca9-22 human gingival carcinoma cells, HSC-2 human mouth carcinoma
