UJI AKTIVITAS ANTIOKSIDAN EKSTRAK ETANOL DAUN GAHARU (AQUILARIA MALACCENSIS LAMK) BERDASARKAN UMUR POHON
ABSTRACT: Utilization of
agarwood leaves(Aquilaria malaccensis Lamk.) suspected contain a chemical
compound of the flavonoids those are flavones, flavonol and isoflavones so that
the leaves used as brewed beverages which serve as antioxidant.Based on that
description, researcher interested in knowing the content of chemical compounds
class and test the antioxidant activity of ethanol extract of agarwood leaves
(A. malaccensis Lamk.). previous research does not regard age of the tree which
is taken its leaves, so that it needed to review that based on the age of the
tree. This research used the trees in age 4 and 7 years after
those were planted in the field. This study aims to knowing chemical
compounds class that contain in agarwood leaves (A. malaccensis Lamk.) which
have a function as antioxidant from the tree in age 4 and 7 years; and to
knowing the power of the antioxidant
activity from ethanol extract of agarwood leaves in age 4 and 7 years.
This research is based on the method of Badan Ditjen POM year 1995. Based
on the result of phytochemicals screening test of simplicia powder and ethanol
extract of agarwood leaves which are the compounds of flavonoids, glycosides,
tannins, steroid/triterpenoids, all of that are the active compounds of
antioxidant. The result of antioxidant activity test using beam
spectrophotometer showed in a wavelength 516 nm at 42th minutes is the result
of ethanol extract of agarwood leaves in age 4 and 7 years have 27,83 ppm and 27,76
ppm of IC50. The result of this test is known that ethanol extract of
agarwood leaves in age 4 and 7 years have a very strong antioxidant activity.
