Three lignans were isolated from a methanol extract of Lindera erytherocarpa Makino (Lauraceae) are evaluated in vitro cytotoxicity using three cancer cell line assay. The compounds were identified as methyllinderone (1), linderone (2), and kanakugiol (3) by spectroscopic methods. Amongst the compounds, methyllinderone (1) showed significant cytotoxicity against mouse melanoma (B16-FlO), human acetabulum fibrosarcoma (HT1080), and choronic myelogenous leukemia (K562) cancer cell lines with $ED_{50}$ values of 2.2, 2.5, 8.3 ${\mu}g/ml$, respectively.
