Testing of chemical compounds on gaharu branches was carried out using the phytochemical screening method, antioxidant testing using the DPPH method, proximate tests including (testing moisture content, ash content, fat content, protein content) and hedonic tests. The results of the phytochemical screening test of gaharu twigs were positive for containing alkaloid compounds of saponins, tannins, flavonoids and steroids/triterpenoids. Antioxidant test results from A. malaccensis Lamk. classified as weak with an IC50 valueof 166.44 μg/ml and the type W. tenuiramis Miq. classified as strong with an IC50 twigs A. malaccensis Lamk obtained a moisture content of 7.6% ash content of 2.4% protein content of 4.81% and 0.69% fat and W. tenuiramis Miq. obtained 8.9% moisture content 5.8% ash content 6.27% protein content and 1.22% fat content.
