Seven compounds, scopoletin (1), p-hydroxyphenethyl trans-ferulate (2), $1-({alpha}-L-rhamnosyl(1;{ ightarrow};6)-{eta}-D-glucopyranosyloxy)-3,4,5-trimethoxybenzene$ (3), benzyl ${alpha}-L-rhamnopyranosyl(1;{ ightarrow};6)-{eta}-D-glucopyranoside$ (4), suberic acid (5), sebacic acid (6) and scopolin (7) were isolated from the methanol extract of the roots of Althaea rosea Canival. Compounds $1;{sim};7$ were first isolated from this plant. The isolated compounds were tested for their cytotoxicity against human cancer cell lines using a SRB method in vitro.
