              ABSTRACT
              In the present study the stems 
                of the Bridelia stipularis (L.) Blume, which is traditionally used by ethnic 
                communities in Sabah, Malaysia, has been investigated for its 
                chemical composition, total flavonoid content (TFC) and total phenolic content 
                (TPC) 
                via Gas-Chromatography-Mass Spectroscopy (GC-MS) 
                analysis consuming hexane, chloroform and ethyl acetate as extraction 
                solvents and gallic acid and quercetin 
                as internal standards. In vitro antioxidant activity (AA) 
                was determined by the application of 1,1-diphenyl-2-picryl hydrazine 
                (DPPH) radical scavenging assay using tert-butyl-1-hydroxytoluene 
                (BHT) as comparative drug. The 
                GC-MS 
                profiling showed the presence of 1-dodecanol (40.917%), 
                oxalic acid, cyclobutyl octadecyl 
                ester (24.985%), 1-octanol,2-nitro (12.424%), benzaldehyde, 2,4-dimethyl- 
                (9.583%), 4-tridecanol (6.359%) and nitric acid, nonyl 
                ester (5.616%) as major constituents. The TPC (224.62 
                ± 0.08 mg QE/g) and TFC (160.48 ± 0.08 mg GAE/g) 
                was reported highest for the most polar solvent i.e. ethyl acetate. 
                The in vitro antioxidant study disclosed highest IC50 value 
                for ethyl acetate (2.15 mg/mL), queued by chloroform (1.19 mg/mL) 
                and hexane (0.89 mg/mL), displaying that polar solvents are good 
                extraction solvents for the identification of free radical scavenging 
                properties, TFC and 
                TPC.

              Dalam kajian terbaharu, batang Bridelia stipularis (L.), Blume secara 
                tradisi digunakan oleh etnik pribumi 
                di Sabah, Malaysia, telah dikaji 
                kerana komposisi 
                kimia, kandungan jumlah flavonoid (TFC) dan

                pengekstrakan pelarut, asid galik dan 
                Quercetin sebagai piawai 
                dalaman. Aktiviti antipengoksida (AA) in vitro ditentukan oleh aplikasi hidrazina 1,1-difenil-2-

                menggunakan tert-butil-1-hidroksitoluen (BHT) 
                sebagai perbandingan dadah. GC-MS pemprofilan 
                mendedahkan kehadiran 
                1-dodekanol (40.917%), asid oksalik, 
                ester oktadekil cyclobutyl
