| Abstract | Henna leaves (Lawsonia inermis L.) are a species of the genus Lawsonia. Henna leaves (Lawsonia inermis L.) contain various secondary metabolites, including phenolic compounds, flavonoids, tannins, and lawsone, which have potential antioxidant activity. This study aimed to determine the total phenolic and gallic acid contents of the ethanolic extract of henna leaves obtained by maceration and ultrasonic-assisted extraction (sonication), as well as to identify the presence of lawsone using Thin-Layer Chromatography (TLC). The study included the characterization of simplicia, phytochemical screening, extraction by maceration and sonication, determination of total phenolic content using the Folin–Ciocalteu method, determination of gallic acid content using UV–Visible spectrophotometry, method validation, and identification using TLC. The results showed that the total phenolic content obtained by the maceration method was 3,35411%, while that obtained by the sonication method was 3,49191%. The gallic acid content obtained by the maceration method was 3,29152%, whereas that obtained by the sonication method was 3,57143% TLC analysis showed that the Rf value of the extract was 0,30 which was close to the Rf value of the lawsone standard 0,31. Based on the results, the maceration method produced higher total phenolic and gallic acid contents than the sonication method. | 1 |
