Background: “Julang-jaling” (Archidendron bubalinum (Jack) I.C Nielsen) fruits are commonly used as traditional food and in the treatment of blood sugar and heart disease. However, the research about the phytochemicals of the parts of this plants and their bioactivity was rare. Objective: The recent study was aimed to analyze volatile compounds in the extract of “julang-jaling” husks and evaluate their antioxidant and antimicrobial activities. Material and methods: The extraction was conducted using n-hexane, ethyl acetate, and methanol as extracting agent. The phytochemical assay was performed for all extracts, and followed by volatile compound analysis using GC-MS. The antioxidant assay was performed using DPPH method, and the antimicrobial activity was conducted using agar disc diffusion method. Results: The phytochemical assay showed that all extracts of “julang-jaling” husks contain various phytoconstituents having potential bioactivity. All extracts exhibit antioxidant activity with different level of activity depend on the type of extract. The IC50 value were 273.57 ppm, 324.913 ppm, 735 ppm, for ethyl acetate, methanol and n-hexane, respectively. All extracts were able to inhibit the growth of Bacillus cereus, with the highest antimicrobial activity was gained for ethyl acetate extract. Both ethyl acetate and methanolic extract have antimicrobial activity toward E. coli, but no extracts yield positive results for Aspergillus flavus and Aspergillus niger. Conclusion: GC-MS analysis revealed the presence of hexadecanoic acids and their ester form in all extract, which might largely contribute in the antioxidant and antimicrobial activity.
