Abstract
This work has investigated the morphology, chemical structure and UV absorption properties of cottonseed hull and kernel, as part of an assessment of these materials for use as potential UV absorbing and/or medical compounds. The morphological analysis of the samples revealed that cottonseed kernel has a porous and homogenous morphology. By comparing the FTIR of cottonseed hull and kernel, it was found that the kernel sample has more polyphenol groups. Moreover, an examination of the UV absorption spectra showed the kernel tissue had stronger absorption spectra in both the UVA (320-400nm) and UVB (290-320nm) regions than material from the hull. Thus, the present study demonstrated that the cottonseed kernel could be a promising source of natural UV absorber.
