Antioxidant activity of selected plants extract for palm oil stability via accelerated and deep frying study

Bio-clay: Antioxidant-rich and stable for body mud scrubs

“…(A-B), respectively. The sample's ability to donate hydrogen to DPPH free radicals can be assessed by the percentage of free radical scavenging activity [ 55 ]. The potential for eliminating free radicals can be seen from the IC 50 value calculated from the regression equation as shown in Fig.…”

“…TPC are essential antioxidants, combatting free radicals such as superoxide, hydroxyl, nitric oxide, and peroxyl radicals, which are relatively stable free radicals and commonly found in the body. These radicals are neutralized by destroying or inhibiting free radicals [ 55 , 57 ]. Moreover, it was found that the antioxidant activities of the different sample extracts correlated significantly with their TPC.…”

“…From the results of the sample analysis, it was found that the values were different. This occurs due to the cultivation period, geographic location, and sample extraction methods [ 55 ]. For example, the % scavenging, TEAC, and TPC of paper flower (Bougainvillea hybrid) was 62.44 ± 0.85%, 17.25 ± 0.19 mg/g sample, and 26.79 ± 0.24 mgGAE/g sample, respectively [ 58 ].…”

Impact of Heavy Metal Pollution in the Environment on the Metabolic Profile of Medicinal Plants and Their Therapeutic Potential

“…When a plant encounters pathogenic microorganisms, it often triggers an oxidative burst as part of its defense response. Antioxidants neutralize excess ROS produced during this response, preventing damage to the plant’s own cells [ 39 , 46 ].…”

“…Antioxidants also participate in the regulation of cellular signaling pathways. They can influence gene expression and signaling cascades, helping plants respond to internal and external stimuli [ 46 , 49 ]. This regulatory role is essential for coordinating various physiological processes in the plant ( Figure 1 ) [ 50 ].…”
