The present study was aimed to examine the chemical composition of the essential oil from the leaves of G. celebica L. (EO-GC) and its cytotoxic and antimicrobial potential. EO-GC obtained by hydrodistillation was analysed using capillary GC and GC-MS. Twenty-two compounds were identified, dominated by α-copaene (61.25), germacrene D (6.72) and β-caryophyllene (5.85). In the in vitro MTT assay, EO-GC exhibited significant anti-proliferative effects towards MCF-7 human breast cancer cells with IC50 value of 45.2 μg/mL. Regarding the antimicrobial activity, it showed better inhibitory effects on Gram-positive bacteria than Gram-negative bacteria and none on the fungi and yeasts tested. © 2019 Informa UK Limited, trading as Taylor & Francis Group. publisher: Taylor and Francis Ltd. date: 2020 type: Article type: PeerReviewed identifier: Tan, W.-N. and Tan, Z.-H. and Zulkifli, N.I. and Nik Mohamed Kamal, N.N.S. and Rozman, N.A.S. and Tong, W.-Y. and Leong, C.-R. and Lim, J.-W.
