Seventeen compounds (1 - 17), ${\beta}$-sitosterone (1), lupenone (2), arborinone (3), ${\beta}$-sitosterol (4), lupeol (5), epi-lupeol (6), taraxerol (7), betulinic acid (8), 24R-methyllophenol (9), germanicol (10), hexatriacontane (11), nonacosan-1-ol (12), benzoic acid (13), tetradecyl(E)-ferulate (14), di(2-ethylhexyl) phthalate (15), trilinolein (16) and monopalmitin (17), were isolated from the methylene chloride-soluble fraction of the cork of Euonymus alatus Sieb. The structures of these compounds were elucidated on the basis of spectroscopic evidence. Compounds 6, 11, 13 and 14 were isolated for the first time from this plant. Compound 4 showed moderate cytotoxic activity with an $IC_{50}$ value of 6.22 ${\mu}M$ in HL-60 cell line. Compound 9 exhibited moderate cytotoxic activity with $IC_{50}$ values of 63.31, 15.45, 15.14 and 21.72 ${\mu}M$ in four kinds of human cancer cell lines, Jurkat T, HeLa, HL-60 and MCF-7, respectively. Compound 17 showed moderate cytotoxic activity with an $IC_{50}$ value of 70.71 ${\mu}M$ in Jurkat T cell line. In addition, compounds 2, 3, 14 and 16 exhibited weak antioxidant activity with $IC_{50}$ values of 151.76, 170.79, 137.46 and 139.37 ${\mu}M$, respectively.
