Nine terpenoids, spinasterone (1), simiarenol (2), phytol (3), lupeol (4), ${\alpha}$-amyrin (5), $1{\beta},4{\beta}$-dihydroxyeudesman-11-ene (6), 3,7-dihydroxyhumula-4,8(15),10(E)-triene (7), 2,6-dihydroxyhumula-3(12),7(13), 9E-triene (8), 23-hydroxybetulin (9) were isolated from the aerial parts of Aster yomena M. Their structures were identified based on 1D and 2D NMR, including $^1H-^1H$ COSY, HSQC, HMBC and NOESY spectroscopic analyses. Compounds 1 - 9 were isolated from this plant for the first time.
