Abstract

Sunscreen is a preparation that is used on the surface of the skin that works to absorb,
scatter or reflect ultraviolet light. Therefore, it is necessary to use the ingredients to become
active ingredients in sunscreen. The research objectives are to (a) determine the content of
secondary metabolites qualitatively from avocado skin extract (Persea americana Mill.). (b)
To determine the total flavonoid content and total polyphenol content of avocado peel extract
(Persea americana Mill.). (c) Knowing the sunscreen activity of avocado skin extract (Persea
americana Mill.). This type of exploratory experimental research is based on a quantitative
approach. The results showed that avocado skin extract (Persea americana Mill.) contained
secondary metabolites. It is known that avocado peel extract has a total flavonoid content of
10.855 mgQE/g extract and a total polyphenol content of 221.593 mgGAE/g extract. It is
known that avocado peel extract (Persea americana Mill.) has sunscreen activity with an SPF
value of 3.887 at a concentration of 500 ppm including minimal protection category. The
results of the activity test showed that avocado skin sunscreen potential had phenolic
compounds. In addition to containing compounds that are antioxidants, tannins and
ceilingoids
