초록

The purpose of this study was to analyze the functional ingredients of Curcumae longae Rhizoma extracts and to confirm the possibility of producing polyvinyl alcohol (PVA) nanofibers using these extracts. Distilled water and ethanol were used as extraction solvents. Terpene and its analogues as well as various volatile and essential oil components were detected in the distilled water and ethanol extracts. The total polyphenol content and flavonoid content showed that the Curcumae longae Rhizoma ethanol extract was higher than distilled water extract at $242.33{\mu}g/ml$ and $166.65{\mu}g/ml$, respectively. PVA nanofibers containing Curcumae longae Rhizoma ethanol extract were electrospun in a relatively uniform manner without the occurrence of beads as a whole. As the content of Curcumae longae Rhizoma ethanol extract increased, the diameter of the fiber increased as well; the range of approximately 330 to 610 nm was added with a 0.25-1.5% addition. The hydrogen bonding between the Curcumae longae Rhizoma extracts and PVA, as well as the resulting degrees of crystallinity, melting point, and increase in heat capacity were identified through a Fourier-transform infrared spectroscopy, X-ray diffraction, and differential scanning calorimetry analysis. Therefore, it was verified that the developed Curcumae longae Rhizoma/PVA nanofiber was created in a state wherein the bond between the molecules were smoothly achieved.
