title: Two new acyclic diterpene-gamma-lactones from Salix matsudan.
abstract: Two new phytane-type diterpene-gamma-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.
