洋苏木(Haematoxylum camp-echianum L.)是我所于1974年引进的,从其红褐色心材中提取的苏木精(Ha-ematine crystat)是动植物制片的一种重要染色剂。广泛应用于科研、教学、医疗等单位。但目前我国所需的苏木精还全部依靠进口。为了减少进口或全部自给,1982年我们从洋苏木提取分离得到苏木精,经化学与光谱鉴定,证明与进口苏 Haematoxylum camp-echianum L. was introduced in 1974 and Ha-ematine crystat extracted from its red-brown heartwood is an important stain in animal and plant products. Widely used in scientific research, teaching, medical and other units. But at present, China needs all hematoxylin imports. In order to reduce imports or all self-sufficiency, in 1982 we extracted from the hematoxylin hematoxylin, chemical and spectroscopic identification, with the import of Soviet
