摘要
甲壳素是资源昆虫蝇蛆的生物活性成分之一,但是,甲壳素不溶于水及常见溶剂,限制了其应用。本研究从蝇蛆壳中提取了甲壳素和壳聚糖,并进一步制备为水溶性羟丙基三甲基氯化铵壳聚糖(HACC)。FTIR光谱分析结果表明:蝇蛆甲壳素和壳聚糖均具有三个典型的酰胺谱带特征吸收峰,分别为1653 cm^(-1)和1621 cm^(-1)(Ⅰ)、1552 cm^(-1)(Ⅱ)、1309 cm^(-1)(Ⅲ)(甲壳素);以及1642 cm^(-1)(Ⅰ)、1589 cm^(-1)(Ⅱ)和1321 cm^(-1)(Ⅲ)(壳聚糖);在HACC中,壳聚糖位于1589 cm^(-1)(酰胺Ⅱ谱带)处的吸收峰消失,但在3021 cm^(-1)和1480 cm^(-1)处出现了两个新的吸收峰。蝇蛆水溶性壳聚糖季铵盐的制备有助于拓展其深层次开发利用。
Chitin is a bioactive polysaccharide presence in maggots of the house fly, a resource insect. However, its applications are limited due to its insoluble in water and most common solvents. In this study, fly maggot chitin was extracted and prepared to chitosan, and hydroxypropyltrimethyl ammonium chloride chitosan （HACC）, a water soluble chitosan salt, was further prepared by addition reaction. The FTIR spectra confirmed the presence of three typical absorption peak of amide bands both in chitin and chitosan： 1653 cm-1 ＆ 1621 cm-1 （Ⅰ）, 1552 cm-1 （Ⅱ） and 1309 cm-1 （Ⅲ） for maggot chitin; 1642 cm-1 （Ⅰ）, 1589 cm-1（Ⅱ） and 1321 cm-1 （Ⅲ） for maggot chitosan, respectively. In HACC, the absorption peak of chitosan at 1589 cm-1 （amide Ⅱ band） disappear, but two new absorption peaks appear at 3021 cm-1 and 1480 cm-1. The preparation of HACC could beneficial for the deep development and utilization of resource Insect.
