茜素红(1,2—二羟基蒽醌—3—磺酸盐,NaH_2ARS)属于蒽醌类化合物,可作染料及指示剂,在生物研究中广泛用着显微镜染色剂,神经组织的活体染色,植物细胞分子中染色体的染色等,天然植物中存在的蒽醌类化合物广泛用作泻剂,也具有抗菌、抗炎和抗癌等许多生理作用。合成它的稀土化合物并研究其性质,对于扩大其应用,研究有关药理作用,开拓稀土药物及其有关化学是有意义的。有关茜素红稀土配合物的稳定常数曾有过报导,但对其固态化合物的研究未见报导。
Alizarin red (1,2-dihydroxyanthraquinone-3-sulfonate, NaH 2 ARS) is an anthraquinone compound that can be used as a dye and indicator. It has been widely used in biological research with microscopic stains, in vivo staining of neural tissues , Plant cells, chromosomes, etc., anthraquinones existing in natural plants are widely used as purgatives, but also has many physiological effects of anti-bacterial, anti-inflammatory and anti-cancer. The synthesis of its rare earth compounds and study their properties, for the expansion of its application, research on pharmacological effects, development of rare earth drugs and related chemical is of significance. There have been reports on the stability constants of alizarin red rare earth complexes, but no reports on their solid state compounds have been reported.
