Two New Acyclic Diterpene-γ-lactones from Salix matsudan

Abstract

Two new phytane-type diterpene-γ-lactones named hanliuine I (1) and hanliuine II (2), were isolated from leaves of Salix matsudana (chinese name “hanliu”, Berberidaceae). Their structures were deduced from 1D and 2D NMR techniques.
