Antioxidant activity of herbaceous plant extracts protect against hydrogenperoxide-induced DNA damage in human lymphocytes

Abstract: BackgroundHerbaceous plants containing antioxidants can protect against DNA damage. The purpose of this study was to evaluate the antioxidant substances, antioxidant activity, and protection of DNA from oxidative damage in human lymphocytes induced by hydrogen peroxide (H2O2). Our methods used acidic methanol and water extractions from six herbaceous plants, including Bidens alba (BA), Lycium chinense (LC), Mentha arvensis (MA), Plantago asiatica (PA), Houttuynia cordata (HC), and Centella asiatica (CA).Method… Show more

“…In this study, comet scoring was performed using a scale of 0 (no damage) to 3 (most damage) in visual analysis in the comet assay between 10 and 30 µM H 2 O 2 damaging concentrations. A significant increase was induced in DNA damage with increasing the concentration of H 2 O 2 (10, and 20 µM; P < 0.001 for all; Figure 2 (18,39,40) and incubation time of H 2 O 2 (5 Min), which were compatible with previous literature (18,41,42). In this study, Primula vulgaris extract, rich in phenolic compounds, was investigated for its protective effect on H 2 O 2 -induced oxidative DNA damage in foreskin fibroblast cells.…”

“…The screening and characterization of antioxidants derived from natural sources has gained much attention and efforts have been put into identifying compounds as suitable antioxidants to replace synthetic ones. The search for phytochemicals with potent antioxidant continues to be of great importance in the search for remedies against free radical-mediated diseases, prevention of oxidative reactions in foods, protection against DNA damage and carcinogenesis and possible substances with wide range of pharmacological activities such as anti-inflammatory, antibacterial and antifungal properties (Lin et al, 2013).…”

From our data, the ethyl acetate stems (EAS) extract stands out with efficient antioxidant capacities (Table 2), which significantly correlated with the phenolic and flavonoid contents (Table 3).…”
