| 摘 要： | 甜菊糖甙(Stevioside)作为一种低热量,安全无毒性的天然甜味剂在国内外已引起了广泛的兴趣,作为主要甜味成分的甜菊糖甙的含量测定是重要课题之一。本文中介绍了在酸性条件下甜菊糖甙与蒽酮反应后,在分光光度仪上以最大吸收波长445nm比色测定的方法。同以前提出的各种测定方法相比,具有操作方便,方法快捷、灵敏,精密度较高等优点。适合在一般实验室使用。

| Abstract: | A spectrophotometric method for 'direct determination of gfocos'des in' stevia is discribed. Steviosides gives a yellow compound after heating, with anthrone in acid medium, which has amaximum absorbance at wave length 445 nm. This method is simple, highly sensitive, rapid and gives flood precision. |
