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.
