摘　　要：蜈蚣是一种传统中药。文章选择聚乙烯吡咯烷酮(PVP)为载体材料,用溶液静电纺丝技术,将采用不同溶剂、不同方式提取的蜈蚣提取物与PVP相互混合,制备了PVP-蜈蚣超细纤维。用扫描电子显微镜观察了PVP-蜈蚣超细纤维的直径和形貌,并采用紫外分光光度法、红外光谱法等光谱分析方法对蜈蚣及其提取物的成分进行分析。实验结果表明:采用不同溶剂、不同方式提取出来的蜈蚣成分不尽相同;中药蜈蚣成分中含有羟基、甲基、羰基、羧酸盐等多种官能团,中药蜈蚣和PVP共混后形成了低共熔混合物。Centipede is a traditional Chinese medicine.The paper chose polyvinylpyrrolidone(PVP)as the carrier material,and mixed with centipede extract that extracted by different solvents and different ways,so as to prepare PVP-centipede ultrafine fibers by electrospinning technology.The diameter and morphology of PVP-centipede ultrafine fibers were observed by using scanning electron microscope.And the components of centipede and its extracts were analyzed by UV spectrophotometry,infrared spectroscopy and other spectral analysis methods.Experimental results indicated that the components of centipede extracted from different solvents and different ways are varied.There are many functional groups in the centipede,including hydroxyl,methyl,carbonyl,carboxylate.When centipede and PVP are blended,a eutectic mixture is formed.
