Investigation of the leaves extract of Litsea lii var. nunkao‐tahangensis led to the isolation of five new butanolides, litsealiicolide A ( 1 ), isolitsealiicolide A ( 2 ), litsealiicolide B ( 3 ), isolitsealiicolide B ( 4 ), and isolitsealiicolide C ( 5 ), along with 17 known compounds. Their structures were determined through in‐depth spectroscopic and mass‐spectrometric analyses. Among the isolates, compounds 1 and 2 were cytotoxic against MCF‐7, NCI‐H460, and SF‐268 cell lines in vitro. Compound 5 and isolinderanolide B ( 6 ) showed marginal cytotoxic activity against these three cell lines in vitro.
