Abstract: 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.
