Moringa (Moringa oleifera), which is native to tropical and subtropical climates, now grows in Korea due to its warming climate. Since it is also imported and used for food and other products in various countries, it is necessary to analyze the properties of moringa being imported into Korea. In this study, the antioxidant activity and total phenol and flavonoid content were high in the leaves and twigs and showed a positive correlation. The mineral content was also high in the leaves and twigs, and potassium ions were the most abundant mineral. In addition, seven phenolic acids (caffeic acid, chlorogenic acid, cinnamic acid, coumaric acid, ferulic acid, gallic acid, and syringic acid) and four flavonoids (kaempferol, myricetin, quercetin, and rutin) were detected in the leaves, twigs, and stems, and the ferulic acid and quercetin content was particularly high. The results of this study can be used as comparative data for domestic moringa growers in the future.
