Antioxidants and chemical compounds of hot water extract agarwood leaves Wikstroemia tenuiramis Miq

One type of agarwood from the Wikstroemia genus is Wikstroemia tenuiramis Miq. The leaves have been used as raw materials for agarwood leaf tea. The aim of the research was to determine the antioxidant activity of W. tenuiramis Miq. agarwood leaf tea in ready-to-drink formulations and chemical compounds contained in hot water extract of agarwood leaf type W. tenuiramis Miq. The method of making tea by boiling for 7 minutes. Analysis of antioxidant activity test using the DPPH method. Gas Chromatography - Mass Spectrometry (GC-MS) instruments was used to analyze chemical compounds in hot water extracts. The antioxidant test results that hot water extracts of agarwood leaves had strong antioxidant activity. The results of the GC-MS analysis contained 33 compounds, with the main compounds being Hexadecanoic acid and methyl ester.
