| Abstract | The skin of longan fruit (Dimocarpus longan L.) is agricultural waste that has the potential to be used as a source of secondary metabolite compounds, especially flavonoids that have various biological activities. Flavonoids are phenolic compounds that have the ability to ward off free radicals so that they have the potential to be developed as raw materials for traditional medicines and pharmaceutical preparations. This study aimed to determine the total flavonoid content of ethanol extract of longan fruit peel (Dimocarpus longan L.) using the UV-Vis spectrophotometry method. The study was conducted experimentally. The simplicia powder of longan fruit peel (Dimocarpus longan L.) is extracted by the maceration method using 96% ethanol solvent. The test for determining flavonoid levels was carried out using the UV-Vis spectrophotometer method using quercetin as the raw solution, then the results were expressed in the form of percentage levels. The results of the study showed that the skin of longan fruit contains flavonoid compounds that have been tested for flavonoid phytochemical screening. The results of ethanol extract of longan fruit peel (Dimocarpus longan L.) in determining total flavonoid levels using the UV-Visible spectrophotometry method resulted in a total flavonoid content of 9,964%. It can be concluded that ethanol extract of longan fruit peel contains various secondary metabolite compounds, and has a high enough level of flavonoids so that it has the potential to be developed as a source of raw materials for pharmaceutical products based on natural ingredients. The suggestion of this study is needed to identify flavonoid compounds in the skin of longan fruit (Dimocarpus longan L.) using more specific analytical methods, such as High Performance Liquid Chromatography (HPLC).
