Among the samples, Sample SP exhibited the highest polyphenolic content, followed closely by Sample SSP, and Sample P. To assess antioxidant capacity, DPPH and ABTS scavenging activities were measured, Sample SP demonstrated the highest DPPH and ABTS scavenging activities, with Sample P and Sample SSP also displaying substantial antioxidant properties. In terms of hydrogen peroxide inhibition, Sample P displayed the highest activity, followed by Samples SP and SSP. These findings suggest that coconut oil samples with higher polyphenolic content, particularly SP, SSP, and P, possess stronger antioxidant properties. Further research is needed to validate these results and explore the potential health benefits of coconut oil. Understanding the antioxidant capacity of coconout oil can contribute to its utilization on promoting human health and well-being.<\/span><\/p>\n[\/et_pb_text][\/et_pb_column][et_pb_column type=&#8221;1_3&#8243;

Among the samples, Sample SP stands out with the highest polyphenolic content at 54.92 (+-) 0.49 mg\/kg. Following closely is Sample SSP with a polyphenolic content of 48.44 (+-) 0.41 mg\/kg, and then Sample P with a content of 38.29 (+-) 0.14 mg\/kg. Sample C, D, and F exhibit relatively similar levels of polyphenolic content, ranging from 20.41 (+-) 0.59 mg\/kg to 20.65 (+-) 1.66 mg\/kg. On the other hand, Samples A, B, and E possess the lowest polyohenolic content, ranging from 13.85 (+-) 1.82 mg\/kg to 17.70 (+-) 0.95 mg\/kg<\/p>\n<p style=\"text-align: left\">Polyphenols are a group of natural compounds found in various foods including coconut oil, and are known for their antioxidant properties (Zeb, 2021). Antioxidants play a crucial role in neutralizing harmful free radicals in the body, which can cause oxidative stress and damage cells (Adwas, 2019). As a result, consuming food rich in polyphenols, like coconut oil, could be associated with potential health benefits.<\/p>\n<p style=\"text-align: left\">In the context of data presented, it can be inferred that the coconut oil samples with higher level of polyphenols, such as P, SP, and SSP, may exhibit greater antioxidant activity vompared to samples with lower levels of polyphenols. This is because polyphenols are responsible for the antioxidant capacity of coconut oil (Famurewa et al., 201).
