Evaluation of Sunflower Sprout Extract as a Bioinspired Support to UV Filtration. [PDF]

open access: yesChemphyschem
The photochemistry of a commercial sunflower sprout extract was compared to that of pure chlorogenic acid (3‐O‐caffeoylquinic acid), a key photoprotective species found in the extract. Steady‐state and time‐resolved spectroscopy experiments revealed virtually equivalent photodynamics between aqueous solutions of the sunflower extract and chlorogenic ...
