Abstract

The objectives of this study were to characterize the antioxidant capacities and phytochemicals such as phenolics and flavonoids in four parts of Euphorbia lathyris L. HPLC was employed to detect the type and content of phenolic acids and flavonoids in the root, stem, seed, and testa of the plant. The total phenolic content (TPC) and total flavonoid content (TFC) were different among various parts of E. lathyris. The highest TPC were found in the testa (290.46 ± 15.09 mg of gallic acid equiv/100 g dry weight (DW)). However, the root contained the highest TFC (215.68 ± 3.10 mg of rutin equiv/g DW). Of the different antioxidant activities detected, DPPH free radical scavenging activity was highest in the testa (61.29 ± 0.29 mmol Trolox/100 g DW), but the highest FRAP antioxidant activity was found in the seed (1131.25 ± 58.68 mg FeSO4/100 g DW of free compounds and 1927.43 ± 52.13 mg FeSO4/100 g DW of bound compounds). There was a positive correlation between the total phenolic contents and DPPH free radical scavenging activity in different parts of E. lathyris. View Full-Text
