Background: Gelatin electrospun fibers incorporated with extracted cardamom Essential
Oil (EO) were developed and characterized.
Materials & Methods: The gelatin solutions were evaluated in terms of conductivity, morphology,
fourier transform infrared spectroscopy, and the effect of cardamom EO on the gelatin fibers.
Cardamom EO showed significant antioxidant activity with IC50 value of 5 μg/ mL. The extract
contained several active components including Cyclohexene, 1-methyl-4-(1-methylethylidene) and
Eucalyptol (1.8-cineol) as the most abundant components.
Results: The images of the scanning electron microscopy revealed formation of nanofibers from
gelatin solution with significant entanglement. Furthermore, discrete beads were appeared by increasing
the concentrations of cardamom EO in the gelatin fibers. Reduction in conductivity parameter
of EO solutions could explain the observed defects. The fourier transform infrared spectra
showed the formation of hydrogen bonds in gelatin fibers. The infrared as well as spectrophotometric
spectra confirmed that EO was effectively involved in electrospun fibers.
Conclusion: In conclusion, gelatin –a natural biopolymer, incorporated with cardamom EO forms
smooth fabricated electrospun nanofibers.
