Project Title Extraction of Anthocyanin from plants and investigating its UV Absorption capabilities
Synopsis

Sunscreens are widely used to protect humans’ skin from harmful UV radiation. However, many sunscreens contain unsafe chemicals, such as oxybenzone and zinc oxide. In this study, anthocyanin from Cordyline fruiticosa leaves, onion peels and purple sweet potato peels were extracted and measured for their anthocyanin content and in-vitro SPF. The effect of UV on the anthocyanin extracts was also investigated. Sunscreen with the anthocyanin extract of onion peel was then made and tested on its ability to absorb UV. Results show that onion peel extract has the highest in-vitro SPF while Cordyline fruiticosa has the highest anthocyanin content. The sunblock containing anthocyanin extract is able to reduce the intensity of UV by about 69%, outperforming the sunblock without anthocyanin. Anthocyanin has the potential to be used as sunscreen agents which could replace the harmful chemicals in current commercial sunblock.
