“…Studies have shown that Opuntia was rich in natural antioxidant compounds such as carbohydrates, flavonoids, mineral amino acids (arginine), phenolic acids (caffeic and gallic), polyphenols, quercetin, tannins, tocopherol, and sulfur amino acids (cysteine, methionine, and taurine) [7][8][9][10][11][12][13][14][15]. Flavonoids of cactus cladodes possessed many notable biological activities; such as inhibition of lipid peroxidation, oxidation of low density lipoproteins [16,17], antiinflammatory, anti-carcinogenic, anti-aggregatory, antioxidant, hypoglycemic and antiviral activities [8,18,19].…”
