ABSTRACT
Two new steroidal ketones (1, 2), together with 10 known steroids (3-12) and five known steroidal saponins (13-17), have been obtained from the pitch of Tetrapanax papyrierus. The structures of 1 and 2 were elucidated as 3ß-hydroxystigmast-8, 22-diene-7,11-dione and 3ß-hydroxystigmast-8-ene-7,11-dione by IR, HR-ESI-MS, 1D and 2D NMR techniques. Except for 4, 14, 15, 16, 13 compounds reported in this paper were isolated from Tetrapanax papyriferus for the first time.
