Styryl- and dihydrostyryl-2-pyrones derivatives from Polygala sabulosa.
Two dihydrostyrylpyrones and a styrylpyrone were isolated from Polygala sabulosa, together with five known styrylpyrones. Their structures were established on the basis of spectral evidence as 4-methoxy-6-(11,12-methylenedioxy-14-methoxydihydrostyryl)-2-pyrone, 4-methoxy-6-(11,12-methylenedioxy-10,14-dimethoxydihydrostyryl)-2-pyrone, and 4-methoxy-6-(11,12-methylenedioxy-14-methoxystyryl)-2-pyrone.
