This work was the first investigation of the essential oil composition of
Goniothalamus tortilipetalus M.R.Hend. The aim of this study is to investigate the essential oil composition extracted from different parts of
Goniothalamus tortilipetalus M.R.Hend., including flowers, leaves, and twigs, and to evaluate their antioxidant and antibacterial activities. The Clevenger apparatus was used for hydrodistillation to prepare the essential oils. The essential oils were investigated using gas chromatography–mass spectrometry (GC-MS). The three major compounds of the flowers were bicyclogermacrene (15.81%), selin-11-en-4-α-ol (14.68%), and
E-caryophyllene (7.02%), whereas the leaves were
p-cymene (39.57%), ascaridole (9.39%), and α-copaene (9.12%). In the case of the twigs,
α-copaene (10.34%), selin-11-en-4-
α-ol (8.85%), and
p-cymene (7.76%) were the major compounds. The flower essential oil showed antioxidant activities with IC
50 values of 725.21 µg/mL and 123.06 µg/mL for DPPH and ABTS assays, respectively. The flower essential oil also displayed antibacterial activity against
Bacillus subtilis,
Staphylococcus aureus,
Micrococcus luteus,
Salmonella typhimurium, and
Shigella flexneri, with the same MIC value of 640 µg/mL.
