Abstract
Four kinds of acetylenes and three kinds of terpenoids were isolated from Solidago altissima L. and characterized by MS, 1H-NMR and 13C-NMR spectroscopy as methyl (Z) -decaene-4, 6, 8-triynoate (Z-dehydromatricaria esther, 1), methyl 10- [(Z) -2-methyl-2-butenoyloxy] - (2Z, 8Z) -2, 8-decadiene-4, 6-diyoate (2), (4Z) -2, 4-decadiene-6, 8-diyn-4-olide (Z-dehydromatricaria lactone, 3), (4E) -2, 4-decadiene-6, 8-diyn-4-olide (E-dehydromatricaria lactone, 4), 13E, 7α-acetoxyl kolavenic acid (solidagonic acid, 5), kolavenol (6), and D : C-friedours-7-en-3β-ol (ilexol, 7). Bioassay of these compounds on the germination of lettuce seeds showed that compounds 1, 2, 3, 4, and 5 exhibited growth inhibitory activity, whereas compound 7 did not exhibit the activity.
