Abstract

The X-ray diffractometric and infrared spectroscopic investigation of crystalline material isolated from the Cactaceae species Opuntia ellisiana shows the presence of a very complex mineral composition, including whewellite (monohydrated calcium oxalate), opal (SiO2), calcite (CaCO3) and glushinskite (dihydrated magnesium oxalate). This is the first report of the presence of magnesium oxalate in plants.

摘要

对从仙人掌科植物椭圆叶仙人掌中分离出的晶体物质进行的X射线衍射和红外光谱研究表明，其矿物成分非常复杂，包括水草酸钙（一水合草酸钙）、蛋白石（二氧化硅）、方解石（碳酸钙）和水碳镁石（二水合草酸镁）。这是植物中存在草酸镁的首次报道。
