【摘要】 甲壳素是药用昆虫蝇蛆的生物活性成分之一,本研究采用酸碱法并辅以微波加热提取蝇蛆甲壳素,继而以碱冻融法制备低脱乙酰度的水溶性甲壳素。FTIR光谱分析结果表明,2种样品均具有3个典型的甲壳素酰胺谱带特征吸收峰,分别为1653cm^-1和1 621cm^-1（Ⅰ）、1 555cm^-1（Ⅱ）、1 309cm^-1（Ⅲ）（蝇蛆甲壳素初提物）,以及1 625cm^-1（Ⅰ）、1 524cm^-1（Ⅱ）和1 305cm^-1（Ⅲ）（水溶性蝇蛆甲壳素）。家蝇蛆水溶性甲壳素的制备有助于拓展其深加式利用。更多还原

【Abstract】 Chitin is one of the bioactive components of medicinal insect maggots. In this study, fly maggot chitin was extracted by acid-alkali method, assisted by microwave heating, and water-soluble chitin with low deacetylation degree was further prepared by alkali-freezing-thawing treatment. FTIR spectral analysis results showed that the two samples had three typical absorption peaks of amide bands of chitin in both samples: 1 653 cm^-1 & 1 621 ㎝^-1（ Ⅰ）, 1 555cm^-1（ Ⅱ） and 1 309 cm^-1（ Ⅲ）, for initial extraction of maggot chitin; 1 625 cm^-1（ Ⅰ）, 1 524 cm^-1（ Ⅱ）, 1 305 cm^-1（ Ⅲ）, for further preparation of water-soluble chitin, respectively. The preparation of water-soluble chitin can be beneficial for the deep development and utilization of medicinal maggots.更多还原
