A phytochemical study on the root of Dendranthema zawadskii var. latilobum Kitamura, using a series of silica gel column chromatography and reversed phase C-18 HPLC chromatography, led to the isolation of (1S, 2S)-1, 2, 3-trihydroxy-1-(3, 4-methylenedioxyphenyl)propane (1), 4-methoxycinnamic acid (2), acacetin (3) and caffeic acid methyl ester (4). The structures of these compounds were determined using spectroscopic analyses (UV, IR, HRTOFMS and NMR), with comparison of their spectral data with previously reported values, Compound 1 was isolated for the first time, with compounds 2 and 4 from this plant reported for the first time. The antibacterial and antifungal activities of the isolated compounds were measured using the disc diffusion method. Also, their cytotoxicities against the cancer cell lines, A549, B16F1 and SK-Mel-2, and brine shrimp lethalities were evaluated.
