Abstract:

Oxidation-reduction potential (ORP) of different saponins and its correlation with free radical scavenging capacitywere studied electrochemically. Results indicated that saponin solutions with low ORP values displayed a weak scavengingcapacity against free radicals (DPPH radical, •OH and O2-•), and vice versa. The free radical scavenging capacity of saponinswas found to be positively correlated with ORP values.

Key words: saponin, oxidation-reduction potential, electrochemical technology, free radical
