用葡聚糖500和聚乙二醇6000，通过离心分离和双水相系统的组合，从米糠中分离出高菲汀含量的颗粒。分离的颗粒主要由植酸、钾和镁组成。分离颗粒的化学组成和电镜观察证实，包埋在成熟稻米糊粉层颗粒中的电子致密物质是植酸的钾和镁盐。
High phytin containing particles were isolated from rice bran by a combination of a differetial centrifugation and an aqueous two phase system, using dextran 500 and polyethylene glycol 6000. The isolated particles consisted mainly of phytic acid, potassium and magnesium. The chemical composition and electron microscopic observation of the isolated particles confirmed that the electron dense material, which is embedded in aleurone particles of matured rice grains, is potassium and magnesium salts of phytic acid.
