Abstract
The new anthraquinones, 7-methylantanthragallol 1,3-dimethyl ether, 7- methyl-anthragallol 2-methyl ether, 6-methylanthragallol 3-methyl ethe r, 8-hydroxyanthragallol 2,3-dimethyl ether, 7-formylanthragallol 1,3- dimethyl ether, copareolatin 5,7-dimethyl ether, copareolatin 6,7-dime thyl ether, 6-methoxylucidin omega-ethyl ether and 6-hydroxyxanthopurp urin, as well as a novel bianthraquinone, bisinaiquinone [10,2'-bi(9-h ydroxy-3-methyl-1,4-anthraquinonyl)] were isolated from the roots of G alium sinaicum. Their structures were established by spectroscopic tec hniques including 2D-NMR. In addition, eight known anthraquinones were also isolated and fully characterized.
