Identifikasi Dan Uji Aktivitas Antioksidan Senyawa Kimia Dari Ekstrak Metanol Kulit Buah Pisang (Musa paradisiaca Linn.)
ABSTRACT: The objective of
these research was measured activity as antioxidant some compounds in methanol
extracts of peel of banana (Musa paradisiaca Linn.), isolated some compounds
which had activities as antioxidant, and determined this structure. Method of
this study was extracted powdered peel of banana with methanol at room
temperature. Extract was concentrated in vaccuo and then successively was
partitioned with n-hexane, chloroform, etyl acetate, and buthanol. Antioxidant
test from each fractions was measured by hydroxyl radical scavenger test with
Fenton reaction method. The result of this study showed activity each fractions
as hydroxyl radical scavenger activity
of chloroform, etyl acetate, and buthanol fraction were IC50 693.15; 2347.40;
and 1071.14 mg/mL respectively. The isolation of secondary metabolite compounds
from chloroform fraction obtained two isolate compounds. Identification by
spectroscopy IR, MS, 1H and 13C NMR one
and two dimension showed that the compounds are 5,6,7,4'-tetrahidroxy-3,4-flavan-diol
and a new compound cyclohexenon derivative
(2-cyclohexene-1-on-2,4,4-trimethyl-3-O-2'-hydroxypropyl ether).
