Abstract
Penelitian ini bertujuan untuk mengetahui struktur metabolit sekunder dari fraksi n-heksana:etil asetat (1:1) kulit batang Cryptocarya morotaiense serta menentukan aktivitas antioksidan dengan metode DPPH. Dari hasil analisis data spektroskopi UV-Vis, 1HNMR dan 13C-NMR diketahui senyawa hasil isolasi yaitu kriptokaryon dan tidak mempunyai aktivitas antioksidan dengan nilai IC50 3.27 x 103 ppm sedangkan standar asam askorbat dan BHT memiliki nilai IC50 berturut-turut adalah 0.27ppm dan 19.63ppm. The purposes of this research were to know secondary metabolite from nhexane:ethyl acetate (1:1) fraction from stem barks of Cryptocarya morotaiense and to determine the antioxidant activity with DPPH method. The result of spectroscopic data analysis, such as UV-vis, 1H-NMR, and 13C-NMR that isolated compound was kryptocaryon and did not have any antioxidant activity with IC50 value was 3,27x103 , while respectively ascorbic acid and BHT as standards had IC50 value were 0,27 ppm and 19,63 ppm.
