从巴戟天(Morinda officinalis How.)根的氯仿提取物中,分离得八个蒽醌化合物,其中二个为新化合物,它们的结构为1,6-二羟基-2,4-二甲氧基蒽醌(1,6-dihydroxy-2,4-dimethoxyanthraquinone,V),1,6-二羟基-2-甲氧基蒽醌(1,6-dihydroxy-2-methoxy-anthraquinone,Ⅵ)。从恩施巴戟(Damnacanthus indicus Linn.)根的氯仿提取物中,分离得七个蒽醌化合物,其中一个为新化合物,其结构为1,4-二甲氧基-2α-羟基蒽醌(1,4-dimethoxy-2-hydroxyanthraquinone,ⅩⅢ)。 Eight quinone compounds were isolated from the chloroform extract of Morinda officinalis How. Two of them were new compounds and their structures were 1,6-dihydroxy-2,4-dimethoxy (1,6-dihydroxy-2,4-dimethoxyanthraquinone, V), 1,6-dihydroxy-2-methoxy-anthraquinone (VI). From the chloroform extract of the root of Damnacanthus indicus Linn., seven quinone compounds were isolated. One of them was a new compound with the structure of 1,4-dimethoxy-2α-hydroxylamine (1). , 4-dimethoxy-2-hydroxyanthraquinone, XIII).
