| Summary: | In recent times, there has been a growing interest in compounds that possess antioxidant properties, particularly in their ability to inhibit reactions caused by free radicals. A study was conducted to examine the antioxidant activity of extracts derived from Cinnamomum cassia and Syzygium aromaticum. Various extracts, including methanol, ethanol, and acetone extracts, were obtained from each sample and the extraction yield, total phenolic content (TPC), and scavenging ability of these extracts were investigated. The total phenolic content (TPC) serves as an indicator of the number of phenolic compounds present in the extract. The study found that extracts with higher TPC values contained a greater quantity of phenolic compounds. On the other hand, the DPPH assay was used to evaluate the radical scavenging activity (RSA) of the extracts. A higher percentage RSA value indicated a higher ability to scavenge radicals. Specifically, the methanol extracts of Cinnamomum cassia and Syzygium aromaticum demonstrated higher radical scavenging activity. Based on these findings, extracts with a greater antioxidant activity are considered to be the most suitable choice for the production of cosmeceuticals. |
