发布时间:2019-02-24 15:41
【摘要】:为设计并合成集助悬、润湿和防腐等功能于一体的混悬剂稳定剂,以提高混悬剂稳定性,保证用药安全有效,以壳聚糖为原料,分别与氯乙酸和柠檬醛反应合成双亲性的柠檬醛缩羧甲基壳聚糖钠盐席夫碱,并通过1H-NMR和元素分析对合成产物进行表征.黏度、亲水亲油平衡值和最低抑菌浓度的测试结果表明,通过引入羧甲基和席夫碱等基团,所合成的席夫碱衍生物具有助悬、润湿和抑菌3种功能;炉甘石混悬剂的稳定性实验表明,该合成产物能够提高混悬剂的稳定性,具有成为多功能稳定剂的潜力.
[Abstract]:In order to design and synthesize suspension stabilizer with the functions of aid suspension, wetting and anticorrosion, which can improve the stability of suspension and ensure the safety and effectiveness of drug use, chitosan is used as raw material. The amphiphilic citral carboxymethyl chitosan sodium Schiff base was synthesized by reaction with chloroacetic acid and citral respectively. The product was characterized by 1H-NMR and elemental analysis. The results of viscosity, hydrophilic lipophilic equilibrium and minimum inhibitory concentration showed that the synthesized Schiff base derivatives had three functions: suspension, wetting and bacteriostasis by introducing carboxymethyl and Schiff base groups. The stability experiment of calamine suspension shows that the synthesized product can improve the stability of suspension and has the potential to become a multifunctional stabilizer.
