摘要
Three new phytane-type diterpene-gamma-lactone shaliuin I (2), shaliuin II (3) and shaliuin III (4) were isolated along with thirteen known compounds from twigs of Salix cheilophila omitted (Chinese name "Shaliu", Salicaceae). The structures of three new compounds have been established on the basis of spectroscopic methods and 2D NMR techniques.
