Abstract

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.

## Abstract In the culture broth of the fungus __Clitocybe diatreta__ a novel diketopiperazine metabolite, diatretol (1), was detected by chemical screening. The structure was established on the basis of ^1^H‐ and ^13^C‐NMR data and single‐crystal X‐ray analysis. Diatretol exhibits a low antibacter
