Abstract
|
|
|
Antioxidant compounds and activities were investigated for both northern (Uiseong) and southern ecotype
(Namhae) domestic garlic stems. The contents of chlorophyll, carotenoid, vitamin C, phenolic compounds and
allicin in garlic stems were measured. Antioxidant activities of methanol and ethanol extracts of garlic stems
were compared determining lipid peroxidation on the linoleic acid system, electronic donating ability (EDA),
superoxide dismutase (SOD)-like activity and nitrite scavenging ability (NSA). The amounts of chlorophyll,
carotenoid, phenolic compounds and allicin in northern ecotype were significantly higher, but vitamin C content
was lower than those of southern ecotype garlic stems. The allicin contents of garlic stems and garlic bulbs
were 26.1±1.0～28.2±0.9 and 33.2±0.7～33.5±0.8 mg%, respectively. All antioxidant activities were higher
in methanol extracts of garlic stems than in ethanol extracts and were higher with northern ecotype than
those with southern ecotype extract. The SOD-like activity of garlic stem extract was higher than that of
garlic bulbs while EDA, lipid peroxidation and NDA of garlic stem extracts were lower than those of garlic
bulbs. Antioxidant activities of garlic stems were more than 50% of garlic bulbs.
