摘要
生物活性测定证明,壳寡糖的诱抗活性与壳寡糖的聚合度及脱乙酰度密切相关,低聚合度(DP<15)及高脱乙酰度的壳寡糖的诱抗活性高。本文采用高效液相色谱(HPLC)法和飞行时间质谱(TOF-MS)法检测壳寡糖的聚合度和脱乙酰度。
The bioactivity tests showed that the induce resistance of oligochitosan was close relation with its degree of polymerization (DP) and its degree of deacetylation (DDA), the oligochitosan with low DP and high DDA has high induce resistance. In this paper, we used HPLC method and TOF-MS method detecting the DP and DDA of oligochitosan.
