Abstract

We identified two compounds that demonstrated 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity from cultures of Lactobacillus plantarum. Spectroscopic analyses proved these compounds to be L-3-(4-hydroxyphenyl) lactic acid (HPLA) and L-indole-3-lactic acid (ILA). The respective EC50 values for HPLA and ILA were 36.6 ± 4.3 mM and 13.4 ± 1.0 mM.
