摘要
对桑蚕蛹皮的成分、结构进行了化学及扫描电镜分析，确定其含有的主要成分及含甲壳素的数量，并对其中的甲壳素、蛋白质和无机盐三者之间的存在方式进行了观察．研究结果表明，蛹体中的甲壳素与灰分主要含在蛹皮中，甲壳素占整个蛹体成分的2.71％，占蛹皮重量的25．5％，蛹皮外表面呈规整的多边形网状结构，蛹皮中蛋白质与蜂窝状的甲壳素相结合，呈层状分布，颗粒状的无机盐填充在甲壳素／蛋白质复合物构成的蜂窝状的空隙中.这为制定提取蛹甲壳素的工艺路线提供了理论依据．
The chemical components of silkworm pupa crust were analyzed, and its microstructure was characterized by using scanning electron microscope. The existing realtion of among chitin,protein and inorganic salt in silkworm pupa crust has been observed. The results show that the major protion of silkworm pupa chitin is in pupa crust, and it accounts for about one forth of crust weight, the out surface of pupa crust is regUlar polygon net vein characteristics. Chitin takes honeycomb shape in chitin - protein complex and conjugated with protein. The inner space of chitin - protein complex net was filled with inorganic salts. Thus the theory basis was provided for working out the process route of isolation pupa chitin.
