It has been investigated the plant of Cinnamomum burmannii Nees ex
Blume from the West Sumatera as sources of antioxidant and antibacteria
compounds. Extraction with n-hexane and ethanol showed the activities of
antioxidant as radical scavenger and as the antibacteria againt Escherichia
coli. Fractional from the crude extract on silica gel column with the n-hexaneethyl
acetate solven gradient system for the n-hexane crude extract and the
ethyl acetate-methanol solven gradient system for the ethanol crude extract
yield three fractions. They are examined with radical scavenger method. The
n-hexane crude extract and its fraction showed weak of antioxidant capacity
but the ethanol crude extract and the two its fractions showed very powerful
of antioxidant capacity with IC50 9.0 ppm, 7,8 ppm and 11.2 ppm respectively.
A Fraction from the n-hexane crude extract (fraction A) and two fractions from
the ethanol crude extract ( fraction B and fraction C) were analyzed UV, IR
and GC-MS. Fraction A consist of trans–cinnamaldehyde (54, 41 %),
cinnamate acid (20,49 %), benzaldehyde (7,95 %) dan
α-phenylacetaldehyde (4,30 %). Fraction B consist of trans–cinnamaldehyde
(68,65 %), methyl cinnamate (9,20 %), methyl hexadecanoic (8,49 %) and methyl-9-Octadecenoic (6,99 %). Fraction C consist of ethyl tetradecanoic
(43,56 %), ethyl laurate (39,48 %), ethyl hexadecanoic (12,16 %), dioctyl
hexenedioic (2,98 %) and diisooctyl 1,2-benzenedicarboxylic (1,83 %).
