摘要
本文对药用辅料甲壳素的质量进行了分析,分析结果:含氮量6.40% ̄6.60%,比旋度+64.5°pH值在7.0以下,干燥失重不超过4.0%,分子量大约1×10^6。
The quality of chitin as pharmaceutical necessity was analysed. The results indicated that its nitrogen content, [a]D25. pH and drying-loss was 6. 40% -6. 60%, +64. 5?+66. 0? ≤7. 0 and ≤4. 0% respectively. Chitin melecular weight was about 1 × 106 daltons.
