| Abstract: | Constituents of the leaves and roots of Ligularia stenocephala MATSUM. et KOIDZ. (Compositae) were investigated. Three compounds, (2E,6E,10E,14E,18E)-2,6,10,15,19,23-hexamethyl-2,6,10,14,18,22-tetracosahexaen-1-ol, (3E,6E,10E,14E,18E)-2,6,10,15,19,23-hexamethyl-3,6,10,14,18,22-tetracosahexaen-2-ol and neophytadiene, were isolated from the leaves of L. stenocephala. Six compounds, 5-acetyl-6-hydroxy-2α-isopropenyl-3β-methoxy-2,3H-benzofuran, 3β-acetoxy-6-acetyl-5-hydroxy-2α-isopropenyl-2,3H-benzofuran, p-hydroxybenzaldehyde, vanillin, 4-hydroxyacetophenone and 4-hydroxy-3-methoxyacetophenone, were isolated from the roots of
L. stenocephala. The structures were determined on the basis of spectral data. |
