N-Bromosuccinimide에 依한 Arbutin의 微量 定量

다국어 초록 (Multilingual Abstract)

In this study new and simple method for microdetermination of Arhutin (10-lmg)
with N-Bromosuccinimide was proposed.
1. Glucose which was produced by hydrolysis of Arbutin did not interfere with
the titration values.
2. In this experiment, it was founded that. using NaHCO₃ crystalline powder gave
better results than NaHCO₃ saturated solution in determining the Arbutin.
3. There was no significant differences between the error of proposed mithod and
that of generally accepted one of Iodimetry.
