Indonesia is a highly biodiverse country second only to Brazil This gives Indonesia enormous potential in ethnopharmacology Previous studies have shown that the leaves of the Brugmansia suaveolens plant also known as Angel trumpet have high antioxidant activity The aim of this study is to test the antioxidant activity of B suaveolens flowers and conduct quantitative screening to determine which compounds play the greatest role in their antioxidant activity This research used the DPPH test and Gas Chromatography Mass Spectrometry GC MS screening Ascorbic acid was used as the comparator in this study Before the DPPH and GC MS testing the samples were extracted using the cold maceration technique with a 95 ethanol solvent Then the samples were concentrated using a rotary evaporator The IC< span> < span> value of the ethanol extract of B suaveolens flowers is 196 16 g mL while the IC< span> < span> value of ascorbic acid the comparator is 3 814 g mL This result shows that the ethanol extract of B suaveolens flowers has moderate antioxidant activity Screening bioactive compounds with GC MS showed that Hexadecenoic acid and Octadecanoic acid play the biggest role in antioxidant activity However the compound with the highest content in the ethanol extract of B suaveolens flowers is scopolamine < span>< p>
