Abstract

Abstract: Gyrinops versteegii is one of the agarwood-producing species that is popularly cultivated in Indonesia. This research aimed to determine the yield, in vitro antioxidant and sunscreen activities of G. versteegii leaf phytochemicals (extracts) from the maceration with ethanol solvents at various polarities (E100%, E50%, E0%) and to analyze the total phenol content (TPC) and total flavonoid content (TFC) of the extracts. The result shows that the polarity of ethanol affects the yield, antioxidant and sunscreen activities, and TPC of the extract. The E50% dissolved extract is the highest yield (19.14%), antioxidant activity (DPPH and CUPRAC test value are 35.82 and 389.52 μmol trolox/g sample), sunscreen activity (sun protection value is 14.9) and TPC (89.35 mg/g AGE) with TFC 0.485%.
