Abstract
Penelitian ini bertujuan untuk mengisolasi, menentukan struktur metabolit sekunder dari fraksi etil asetat kulit batang Nangkadak, serta menentukan aktivitas antioksidan menggunakan metode DPPH. Berdasarkan analisis data spektrum UV Vis, FTIR, 1H-NMR, dan 13C-NMR diketahui senyawa hasil isolasi adalah artokarpin (7). Hasil uji aktivitas antioksidan menggunakan metode DPPH menunjukkan nilai IC50 pada artokarpin (7) adalah 38,90 ppm yang berarti senyawa tersebut mempunyai aktivitas antioksidan yang kuat. ************* The purposes of this research were to isolate the secondary metabolite from ethyl acetate extract of Nangkadak bark, determine the structure of the isolated compound and its antioxidant activity using DPPH method. Data analysis result such as UV-Vis, FTIR, 1H-NMR and 13C NMR have shown that the isolated compound was Artocarpin (7). The value of IC50 was 38,90 ppm. The isolate has strong antioxidant acitivity.
