Abstract

Momordica subangulata Blume is a plant which belongs to the Cucurbitaceae family. It can be used as herbs and only found in the South of Thailand, especially in Nakhon Si Thammarat. There are no such a report on its antioxidant activity and total phenolic content. The study aims to determine and compare total phenolic content and antioxidant activity in different parts of the plant including its leaves, roots, vines, pulp, barks and seeds. The DPPH assay and the Folin-Ciocalteu assay were applied for determining antioxidant activity and total phenolic content. The methanol extract of dried barks contained the highest antioxidant activity (IC50 = 10.85 ± 1.13 mg/L) followed by seeds, pulp, roots, leaves and vines. While the highest phenolic content in total was present in methanol extracts of M. subangulata dried leaves (80 ± 1.46 mg GAE/100 g DW). The results suggest that the plant of M. subangulata is a good natural source of antioxidants and the further studies on their pharmacological properties should be undertaken.
