摘要
从广西血竭的石油醚和醋酸乙酯部位中分得６个化合物。根据理化常数和光谱性质鉴定它们的化学结构分别为１，２，４，５－四氯二甲氧基苯、正二十二烷醇、十八碳饱和脂肪酸乙酯、二十碳饱和脂肪酸乙酯、刃藜芦醇、４，７－二羟基黄酮。其中１，２，４，５－四氯二甲氧基苯为新化合物。
Six
constituents have been isolated from the petroleum ether and ethyl
acetate extract fractions of Dra-caena cochinensis.Their structures
have been identified as 1.2,4,5-tetrachloro-3 ,
6-dimethoxy-benzene,docosyl alco-hol, octadecyl acetate,eicosyl
acetate,resveratrol and 4',7-dihydroxy-flavone on the basis of
physical, chemical andspectral deta.Of these compounds
1,2,4,5-tetrachloro-3,6-dimethoxy-benzene is a new one.
