Table 3 Peaks appeared in FT-IR spectra for fermented extract with and without tetrachloroauric acid solution

1

The broad peaks are centeracteristic to the presence of –NH₂amine group and –OH stretching groups in alcoholic and phenolic compounds. Noruzi et al. 2011increased intensity which may be due to binding of gold ions to OH group. Rastogi and Arunachalam 2011

2

Corresponds to aliphatic C-H stretching. Noruzi et al. 2011

3

centeracteristic to the carbonyl group. This red shift may indicate oxidation of carbonyl group during the reaction and hence reducing gold to AuNPs. Rastogi and Arunachalam2011

4

May be ascribed for the presence of primary amine group C-N stretching. Kumar et al. 2012

6

May be attributed to SO₂ absorption of sulfones present in garlic. Rastogi and Arunachalam2011

7

Signifies the presence of R-CH group Noruzi et al. 2011
