Abstract

Red and green leaves of the pucuk merah (Syzygium myrtifolium Walp.) contain flavonoids, saponins, and tannins which have the potential as antioxidants. The purpose is test out the antioxidant activity of red leaves and green leaves infusions of red shoots (S. myrtifolium). Test material is extracted using infusion method. The testing of antioxidant activity using 1,1-diphenyl-2-picrylhydrazyl (DPPH) method. The free radical concentration of DPPH was analyzed using UV-Vis spectrophotometer after addition of various concentrations of S. myrtifolium leaves infusion extracts. Various concentrations of S. myrtafolium leaves infusion extracts used were 20 ppm; 10 ppm; 5 ppm; 2.5 ppm; 1.25 ppm; 0.625 ppm. Vitamin C solutions as the positive control were prepared on 5; 2.5; 1.25; 0,625; 0.3125 ppm. The result of the experiment showed the thick red and green leaf extract has IC50 value of 11,130 ppm and 10,522 ppm. The antioxidant activity of green leaf extract is higher than the red leaf extract. Research on green leaves extract of S. myrtafolium is suggested for further research as anticancer.

Abstract

Daun merah dan hijau tanaman pucuk merah (Syzygium myrtifolium Walp.) memiliki kandungan flavonoid, saponin, dan tanin yang berpotensi sebagai antioksidan. Tujuan penelitian ini ialah menguji aktivitas antioksidan infusa daun merah dan daun hijau tanaman pucuk merah (S. myrtifolium). Bahan uji diekstraksi menggunakan metode infusa. Pengujian aktivitas antioksidan menggunakan metode 1,1-diphenyl-2-picrylhydrazyl (DPPH). Konsentrasi radikal bebas dari DPPH dianalisis menggunakan UV-Vis spectrophotometer setelah penambahan ekstrak infusi daun S. myrtafolium dengan konsentrasi 20; 10; 5; 2,5; 1,25; 0,625 bpj. Larutan vitamin C sebagai pembanding positif digunakan dengan konsentrasi sebesar 5; 2,5; 1,25; 0,625; 0,3125 bpj. Hasil analisa menunjukkan bahwa ekstrak infusa daun merah dan hijau memiliki nilai IC50 masing-masing sebesar 31,68 bpj dan 30,56 bpj. Aktivitas antioksidan ekstrak infusa daun berwarna hijau lebih tinggi dibandingkan daun berwarna merah. Penelitian ekstrak daun berwarna hijau S. myrtafolium perlu dilanjutkan terutama sebagai antikanker.
