Four undescribed butanolides, linderangolides A-D (1-4), along with four known congeners, lincomolide A (5), (-)-epilitsenolide C2 (6), (-)-epilitsenolide C1 (7) and litseakolide H (8), were isolated from the roots of Lindera angustifolia. The planar structures of 1-4 were elucidated based on extensive spectroscopic analyses, the relative and absolute configurations of 1-4 were determined by the NOESY spectra and the comparison of calculated and experimental ECD. The cytotoxic activities of all isolated compounds were tested, 4 showed inhibitory activity against SGC-7 cells with IC 50 value of 6.62 μM.
