AbstractWhite dammar is an oleo-gum resin obtained from Vateria indica L. (Dipterocarpaceae) and known to possess diverse biological activities. This study examines the chemical composition, antimicrobial, antioxidant activities of essential oil extracted white dammar. The constituents were identified by gas chromatography coupled with mass spectrometry (GC-MS) flame ionization detection (FID). A total 18 compounds constituting 97.15% identified, which consist β-caryophyllene (36.32%), α-humulene (14.31%), β-humulene (9.73%), caryophyllene oxide (8.28%), allo-aromadendrene (5.63%) junenol (5.1%). antimicrobial activity was measured means disc diffusion assay, minimum inhibitory concentration (MIC), bactericidal/fungal concentrations (MBC/MFC). highest shown against Bacillus cereus (MIC/MBC = 31.2/62.5 μg/mL) also Staphylococcus aureus 62.5/125 μg/mL), whereas only a moderate level recorded Salmonella typhi 125/250 Vibrio cholerae, MRSA 250/500 Candida albicans (MIC/MFC μg/mL). Antioxidant evaluated 2,2-diphenyl-1-picrylhydrazyl (DPPH) ferric-reducing power (FRAP) assays; IC50 value, 29.42 μg/mL FRAP 166.5 ± 2.2 μmol Fe2+/g indicated that exhibited adequate activity.

The aim this work understand historical context ethnobotanical value century through analysis (1885) by Nery, well bring light importance very influential propagandist, has been forgotten nowadays.
