In this study, chaste berry oil and red clover extract were combined for the first time in nanoemulsion and nanofiber form. To that end, it was first demonstrated that nanoemulsions could be prepared separately using chaste berry oil and red clover extract, followed by the production of red clover extract-in-chaste berry oil nanoemulsions. All components were added individually and in combination to prepare pectin-stabilized emulsions, yielding the following results: Regardless of the type of nanoemulsion, the use of pectin led to a substantial increase in droplet size (e.g., from 113–233 to 287–845 nm red clover extract-in-chaste berry oil). Pectin/herbal component nanofibers were able to be obtained when a feed rate of 0.5 mL/h was used under an applied voltage of 15 kV and the needle-collector distance was set to 21 cm. While the fiber diameter of pure pectin nanofibers was approximately 400 nm, the addition of herbal components with/without surfactant to the solutions increased the fiber diameters (713–823 nm for red clover extract-in-chaste berry oil). In addition, nanofibers with large fiber diameters exhibited generally big pore sizes.
