Abstract : Universiti Pendidikan Sultan Idris
The essential oil of the leaves of Sarcotheca laxa (Ridl.) Knuth was analysed by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS). Thirty-two chemical components, comprising 97.4% of the total oil composition were identified. βCaryophyllene (24.5%), δ-cadinene (13.8%), germacrene D (8.6%), bicyclogermacrene (6.5%), and aromadendrene (5.2%) were the most abundant components of the essential oils of S. laxa. The antioxidant and anti-inflammatory activities were determined by 2,2- diphenyl-1-picrylhydrazyl (DPPH) and lipoxygenase inhibition, respectively. The essential oil showed significant radical scavenging activity with 50% inhibition (IC ) values of 75.2 50 mg/mL and moderate anti-inflammatory activity with an IC value of 55.7 mg/mL. To the 50 best of our knowledge, this is the first study on the composition and bioactivities of the essential oil report concerning the genus Sarcotheca.
