Ten compounds (1 - 10), palmitic acid (1), 10-nonacosanol (2), pentacosan-1-ol (3), phytol (4), ${eta}$-sitosterol (5), ${eta}$-sitosterol-3-O-${eta}$-D-glucopyranoside (6), 2,4-dihydroxycinnamic acid (7), hyperoside (8), uridine (9) and adenosine (10), were isolated from the n-hexane and EtOAc-soluble fractions of the aerial parts of A. dioicus var. kamtschaticus (Rosaceae). The structures of these compounds were elucidated on the basis of spectroscopic evidence. All compounds (1 - 10) were isolated for the first time from this plant. Cytotoxicity of 1 - 10 against Jurkat T (T-lymphocytic leukemia cells), HeLa (Human cervical epitheloid carcinoma cells), MCF-7 (Human breast cancer cells), and HL-60 (Human promyelocytic leukemia cells) cell lines was measured. Compound 6 showed good cytotoxicity against HL-60 cell line with $IC_{50}$ value of 8.13 ${mu}g/mL$. In addition, compounds 7 and 8 exhibited antioxidant activity with $IC_{50}$ values of 16.30 and 12.42 ${mu}g/mL$, respectively.
