“…In the aqueous extract, the highest concentration of Gallic acid was 33.69 ppm, and the lowest concentration was for Kaempferol at 11.48 ppm. These findings are consistent with previous research [29] and indicate that Portulaca oleraceae L. is a potential source of local food of high quality With ingredients (active compounds) that have biological activity , including vitamin E and antioxidants. It has been highlighted in previous studies [20] that the phenolic compounds extracted from pomegranate peels contain a high percentage of Gallic acid in all the extracts, with a noticeable superiority in the alcoholic extract.…”

“…Finally, at a concentration of 250 mg/ml, all extracts showed 100% removal of hydrogen peroxide, indicating their potent antioxidant properties. These findings align with previous research [32], which demonstrated that Portulaca oleraceae L. used in disease treatment possesses natural antioxidants. Additionally, vitamin C acts as a scavenger for free radicals and can interact with superoxide anions, hydroxyl radicals, and lipid peroxides.…”

“…These findings align with previous research [31] indicating All parts of Portulaca oleraceae L. contain vitamin E, vitamin A, carbohydrates, L-norepinephrine, fructose, vitamin B1, and vitamin B2. Additionally, studies [32,33] have highlighted that Portulaca oleraceae L. can A source of high quality local food and biologically active components due to its content of Vitamin E and antioxidants. Vitamin E in the body acts as an antioxidant against free radicals important in preventing peroxidation of unsaturated fatty acids' membranes.…”

“…Additionally, vitamin C acts as a scavenger for free radicals and can interact with superoxide anions, hydroxyl radicals, and lipid peroxides. Vitamin C can also prevent the formation of superoxide radicals, hydroxyl radicals, peroxyl radicals, singlet oxygen, and hydrogen peroxide [32]. [42] mentioned that the reason for the antioxidant activity is due to phenolic compounds It was also shown [44] that the extracts of sesame casings and sesame oil residues contain good antioxidants…”

The phenolic compounds present in the four extracts of both stems and leaves of the Portulaca Oleraceae L. were diagnosed using HPLC, and the following observations were made: In the alcoholic extract of the leaves, the highest concentration was found in Gallic acid at 77.89 ppm, followed by other phenolic compounds represented by Quercetin, chlorogenic acid, Ferulic acid, Kemopferol, and p-Coumaric at concentrations of 55.8, 50.22, 40.25, 24.15, and 19.25 ppm, respectively. In the aqueous extract of the leaves, the highest concentration was found in Gallic acid at 62.59 ppm, followed by other phenolic compounds Quercetin, chlorogenic acid, Ferulic acid, p-Coumaric, and Kemopferol at concentrations of 41.25, 40.23, 29.58, 16.25, and 16.22 ppm, respectively. In the alcoholic extract of the stems, it was found to contain four phenolic compounds with Gallic acid having the highest concentration at 40.56 ppm, followed by chlorogenic acid, Quercetin, and Kemopferol at concentrations of 33.65, 30.25, and 14.25 ppm, respectively. In the aqueous extract of the stems, it was found to contain four phenolic compounds with Gallic acid having the highest concentration at 33.69 ppm, followed by Quercetin, chlorogenic acid, and Kemopferol at concentrations of 21.45, 20.58, and 11.48 ppm, respectively. The vitamin C and vitamin E contents were evaluated in the extracts. The highest concentration of vitamin E was found in the aqueous extract of the leaves, followed by the alcoholic extract of the leaves, the aqueous extract of the stems, and the alcoholic extract of the stems, with concentrations of 54.1, 33.5, 31.5, and 25.9 ppm, respectively. As for vitamin C concentration, it was found to be highest in the aqueous extract of the leaves, followed by the aqueous extract of the stems, the alcoholic extract of the leaves, and finally the alcoholic extract of the stems, with concentrations of 85.6, 66.5, 52.8, and 35.6 ppm, respectively. The antioxidant activity of the aqueous and alcoholic extracts of the leaves and stems of Portulaca Oleraceae L. was measured by assessing the removal percentage using the FeCl2 and H2O2 methods. The alcoholic extract of the leaves showed the highest removal percentage of 94.73% at a concentration of 150 mg/ml using the FeCl2 method, and the highest DNA protection percentage of 92.73% at a concentration of 150 mg/ml using the H2O2 method.
