## 3 Results and Discussion
### Antioxidant Properties  
Because of the high content of saturated and unsaturated fatty acids of both PSO and SB, they are extremely sensitive to oxidation and it is usually suggested that they be encapsulated. In Table 5, results of the antioxidant tests performed are summarized. Fibers obtained from pure PLA and PVP also had some antioxidant effect, probably because of specific morphology and surface properties. The trend noticed in antioxidant properties is that high concentration of oil loading manifested lower antioxidant activity. Within PLA-series of samples, the decrease of the activity can be explained as the effect of immiscibility of higher loadings of oils with PLA, inducing orientation of oil contents more to the surface of the fibers. As the electrospinning process was done at room conditions in the presence of the air, oxidation of the oil available on the surface might occur. \begin{table}

Table 5: Antioxidant Properties Determined by Different Assays. PSO: Pomegranate Seed Oil; EP: Ethanolic Extract of Fermented Pomegranate Juice; SB: Sea-buckthorn Oil. Antioxidant activity of pure components was also examined by using 1 mg instead of 10 mg of pure component, like it is usually done, to achieve more comparable results (Table 5). The reason for this is the assumption that ex. 10 mg of PLA-10 PSO contain 1 mg of PSO. Comparing the antioxidant activity of pure fatty oils and appropriate nonwoven mats, it can be seen that encapsulated forms have a few times higher antioxidant capacity. As electrospinning is a nano-technique and by forming nanofibers finer dispersion of active compound is achieved, this might be the reason for the enhanced antioxidant activity. It is already demonstrated that compounds on micro and nano level behave in a totally different manner, with the more potent activity of nanosized components, which is one of the many advantages of using nanotechnology.
