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 μg/ml and 166.65 μg/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.
