Abstract

This study aims to investigate antioxidative and antibacterial properties of fresh garlic (non-aged, NG) and aged garlic (AG) by-products extracted with distilled water, ethanol, or chloroform. To determine their antioxidative and antibacterial capacities, 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assay, 2,2'-azino-bis-3-ethylbenzothiazoline-6-sulfonic acid (ABTS) radical scavenging assay, and H 2 O 2 radical scavenging activity, Fe 2+ chelating activity, total ferric reducing antioxidant power (FRAP), and disc diffusion tests were performed. Total phenol and flavonoid contents from distilled water extract of AG were significantly higher than those of NG. DPPH, ABTS, FRAP, and H 2 O 2 scavenging activities of distilled water extract of AG were higher than those of NG. However, Fe 2+ chelating activities of ethanol and chloroform extracts were higher than those of distilled water extracts for both NG and AG. Antibacterial effects of AG were higher than those of NG. In conclusion, aged garlic showed more potent antioxidant and antibacterial effects than fresh garlic.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
