The purpose of this study was to determine whether addition of polyvinyl alcohol (PVA) to Chelidonium majus distilled water and ethanol extract could produce hybrid nanofiber through electrospinning process. The electrospinning process used PVA concentration at 12 wt%, voltage of 10 kV, and a tip to collector distance of 15 ㎝. Total polyphenol and total flavonoid contents were measured in order to verify the antioxidant activity of Chelidonium majus extract. The morphology of Chelidonium majus/PVA nanofibers produced through electrospinning was confirmed through scanning electron microscope (SEM). Coupling between Chelidonium majus extract and PVA molecule was identified via fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), and differential scanning calorimetry (DSC) analysis. Total polyphenol contents of distilled water extract and ethanol extract were 38.4 ㎎/g and 60.58 ㎎/g, respectively. Total flavonoid contents of distilled water extract and ethanol extract were 14.88 ㎎/g and 52.82 ㎎/g, respectively. The diameter of the PVA nanofiber was about 250 ㎚. After Chelidonium majus extract was added, the diameter of nanofiber was increased to be over 400 ㎚. As the concentration of Chelidonium majus extract was increased, the diameter of Chelidonium majus/PVA nanofiberalso was also increased. Without beads and incomplete spinning forms, the nanofibers were evenly spun. Hydrogen bond between Chelidonium majus extract and PVA and subsequent reduction in the degree of crystallization, melting point, and thermal capacity were confirmed by FT-IR, XRD, and DSC analysis. These results demonstrated that nanofiber could be produced after molecular binding is completed.
