Abstract
Gynmena inodorum (GI) is a green leafy vegetable used in the Northern Thai cuisine which has antioxidant activities and may be applicable for preventing oxidative stress and aging-related disease. However, understanding the relationship between GI phytonutrients and their antioxidant properties has been unclear. The aims of this study were to identify the GI leaf phytochemicals and to study their antioxidant activities. A chromatogram of LC-ESI-MS/QTOF-MS showed that the GI leaves were potentially composed of phenolics, quinic acids, flavonoids, and triterpenoid saponins. This study was able to authenticate quercetin, kaempferol, and triterpenoid GIA1 in the samples. The GI materials with high contents of phenolics, flavonoids, quercetin, and kaempferol showed significant relation to antioxidation and protection in endothelial cell death suppressed by reactive nitrogen species. Meanwhile, triterpenoids had a low antioxidant impact. Ultimately, GI leaves with high phenolic compounds are a promising raw material to develop as an antioxidant functional food.
