Abstract
In this study, the antioxidants and photosynthetic compounds of Verdolaga were examined. Compounds were extracted from distinctive segments of the verdolaga using various solvents such as methanol (40, 60, 80%), ethanol (40, 60, 80%), acetone (40, 60, 80%), and deionized water. The use of 80% methanol led to the highest extracted concentration of phenolic substances and flavonoids. The extracted products (Leaves, Stem strips, and Root strips) were evaluated for their radical scavenging capabilities with DPPH (IC50= 22.26, 20.56, and 32.10), and ABTS (IC50= 2.86, 3.70, and 5.24), reducing power (EC50= 15.70, 16.39, and 21.69), and peroxide scavenging activity (1C50= 1.717, 2.937, and 3.255), respectively. The extracted products were analyzed by a gas chromatography-mass spectrometer. Peroxidase, catalase, and polyphenol oxidase assays were completed for the crude extract of verdolaga’s leave, stem strips, and root strips. As indicated by these tests, extracts of the verdolaga’s roots, stems and leaves using 80% methanol yielded high antioxidant activity. The most elevated concentrations of extracted chlorophyll, lycopene, and carotenoids were from the leaves and the highest concentration of extracted tannin was noted from strips of stems. The highest measures of peroxidase and polyphenol oxidase were identified in root strips and the highest units of catalase was identified in leaves.
Highlights
Reactive oxygen species (ROS) are produced in higher volumes during tissue injury
The capacity for antioxidant activity in plant tissues is related to the level of cell-reinforcing substances that are present, including phenolic compounds, carotenoids, tocopherol, ascorbic acid, and compounds that are able to catalyze the scavenging of free radicals [25]
The peroxidase enzyme activity was high in verdolaga root strips, stem strips and leaves (225 ± 0.124, 49 ± 0.86 and 71.5 ± 0.101 units per gram of tissue, respectively)
Summary
Reactive oxygen species (ROS) are produced in higher volumes during tissue injury. An excessive amount of ROS can denature deoxyribonucleic acid (DNA) and proteins, disrupt cell layers, and negatively affect lipids through chain reactions [1]. The production of reactive oxygen species (ROS) mediated lipid peroxidation plays a key role in cell death, including autophagy, ferroptosis, and apoptosis Cell reinforcements, such as atoms that have the capability to neutralize radical, protect against these damages. Portulaca oleracea, (common verdolaga) is an imperative restorative plant with range of pharmacological benefits, including the ability to increase the rate of tissue repair and antimicrobial activity It contains vitamins A and C, omega-3 unsaturated fats, β-carotene, and α-linolenic acid [11]. The target of this study was to explore the use of different solvents (methanol, ethanol, acetone and water) to extract phenolic substances and flavonoids, and to appraise whether extracts from the leaves, root strips, and stem strips of Verdolaga had the best cancer preventing characteristics
