Abstract
Fructooligosaccharide FOS a prebiotic was extracted from the grain of Coix lachrymajobi Linn Job’s tears by hot water extraction at 60 °C for 1 h The resulting dried powder extract was assayed for FOS content of 1kestose GF2 nystose GF3 and 1βDfructofuranosylnystose GF4 using HPLC equipped with RI detector Total FOS content of the extract was 2498 ± 748 g/100 g crude extract The biological activity including antioxidant and cytotoxicity of the FOScontaining extract was determined The antioxidant activity by DPPH free radical scavenging of FOScontaining extract was comparable to vitamin C 097 fold of vitamin C with a slight lipid peroxidation inhibition activity The extract exhibited no cytotoxic effect on normal human skin fibroblast These results have confirmed not only the source of FOS from Job’s tears extract but also its potential application as antioxidant in food or cosmetic products
