| Abstract | Roi Et province is a source of variety of local edible plants which are popularlyconsumed by people. This research aimed to compare the total phenolic contents andantioxidant activity of local edible plants in Roi Et province obtained from water and ethanolsolvent extraction, and to use the information as a guideline for selection and developmentof these local edible plants for the development of related products. Ten popular localedible plants were extracted with water and ethanol, determined total phenolic contentsusing Folin-Ciocaltue reagent method, and antioxidant activity by 2,2'-Azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) cation radical - scavenging assay or ABTS methodand Free radical scavenging activity or DPPH method. The results showed that, the ethanolextracts of all local edible plants contained higher total phenolic content and antioxidantactivity than those of the water extracts, except for the young shoots of Joseph's Coat.The plant containing the highest total phenolic compounds extracted with ethanol were theyoung leaves of Terminalia chebula. As for antioxidant activity using ABTS method, youngleaves of Kradonbog extracted with ethanol displayed the highest percentage of free radicalinhibition which were higher than that extracted by water. The 10 local edible plants wereextracted with ethanol and tested for antioxidant activity by DPPH. Results showed that the5 local edible plants that could inhibit free radicals more than 80% were young leaves ofCowa, Chebulic Myrobalans, Mek, Kradonbog and Somlom. They were suitable for thedevelopment of beneficial products. |
