PENETAPAN KADAR FENOLAT TOTAL DAN UJI AKTIVITAS ANTIOKSIDAN EKSTRAK KULIT SEGAR BUAH MANGGIS (Garcinia mangostana Linn.)
ABSTRACT: The determination
of totally phenolic
compounds in methanol
extracted of cortex
fruit of Garcinia manggostana
Linn has been
done by Folin-Ciocalteau method.
The antioxidant activity has
been performed using
1,1-diphenyl-2-picrihydrazil
(DPPH) as reagent,
that measured
spectrometrically compared with
gallic acid as
antioxidant standard compound. The
total phenolate compounds
found in fresh
peel of mangosteen
was 1,64±0.18% w/w which calculated as gallic acid equivalence and the antioxidant
activity with a value of IC50 was 251,12
µg.
