ABSTRACT
Salam leaf (Syzygium polyanthum Wight Walp) contains flavonoids, tannins and essential oils that act as antioxidants. Antioxidants react with 1,1-diphenyl-2-picrylhydrazyl (DPPH) obtained from free radicals and reduce DPPH. The purpose of this study was to investigate the salam leaf extract were formulated in a lotion with antioxidant activity assay. Lotion is intended for external use as a protective skin. Salam leaf extract obtained by maceration in 70% ethanol to obtain a thick extract. Determination of antioxidant activity by DPPH method. The results showed that the lotion antioxidant assay with IC50 of 105,4 ppm.

ABSTRAK
Daun Salam (Syzygium polyanthum Wight Walp) memiliki kandungan senyawa flavonoid, tanin dan minyak atsiri yang berfungsi sebagai antioksidan. Antioksidan bereaksi dengan 1,1-difenil-2-pikrilhidrazil (DPPH) yang menstabilkan radikal bebas dan mereduksi DPPH. Tujuan dari penelitian ini adalah untuk mengetahui esktrak daun salam dapat diformulasikan dalam sediaan lotion beserta aktivitas antioksidannya. Lotion dimaksudkan untuk pemakaian luar kulit sebagai pelindung. Ekstrak daun salam diperoleh dengan cara maserasi dengan etanol 70% hingga diperoleh ekstrak kental. Penentuan aktivitas antioksidan dilakukan dengan metode DPPH. Hasil penelitian menunjukkan sediaan lotion antioksidan yang paling besar dengan IC50 105,4 ppm.
