Ten new (+)-hydroxybutanolides, linderanolides A-E and isolinderanolides A-E, along with one known one have been isolated from the leaves of Lindera glauca. On the basis of spectroscopic methods and chemical evidence, linderanolides A-E were shown to be (3R,2Z)-3-hydroxy-4-methylenebutanolides having 2-((11E)-11-tetradecenylidene), 2-tetradecylidene, 2-((7Z,10Z)-7,10-hexadecadienylidene), 2-((7Z)-7-hexadecenylidene) and 2-hexadecylidene side-chains, respectively, while isolinderanolides A-E were their corresponding (2E)-isomers.
