Comparison of Phenolic Content and Antioxidant Activities of Extracts of Phytolacca americana Plant Based on Some Different Habitats from Türkiye

OpenAlex English

In this study, leaf and fruit samples of Phytolacca americana collected in the early, mature and senescence period from localities with different habitat characteristics (non-polluted, polluted and wetland) were studied. The total phenolic content, 2,2-diphenyl-1-picrylhydrazyl (DPPH), radical scavenging activity and iron (III) reduction antioxidant power (FRAP) of the water and methanol extracts of the samples dried in oven and at room temperature were evaluated and compared as statistically. According to the results of the analyses, the highest phenolic content (263.25 mg GAE/g sample) was found in the leaf parts of the plant collected from the wetland during the senescence period, dried at room temperature and extracted with water. The lowest phenolic content (0.22 mg GAE/g sample) was determined in water extract of the fruit parts of the plant collected from the same locality in the same period. Among the antioxidant activity values determined, the highest and lowest findings belong to these samples. It can be concluded that each tested variable is statistically significant for both the leaf and fruit parts, and by bringing these variables under suitable conditions, biochemically more efficient use of plants can be achieved.
