ABSTRACTThe objective of this study was to determine the chemical compound in leaves, stem, and root by GC-MS technique and antioxidant activity of torbangun leaves (Coleus amboinicus Lour). The torbangun leaves ethanol extract were tested to antioxidant activity assay using DPPH, and á-glucosidase inhibitory effects was measured with a spectrophotometric method. The analysis of leaves revealed the presence of Carbamic acid, monoammonium salt (CAS) Ammonium carbamate (11.73%), Hexadecanoic acid (CAS) Palmitic acid (8.35%), I-Limonene (5.92%), Heptadecene-(8)- carbonic acid-(1) (4.76%), Oxacycloheptadec-8-en-2-one (CAS) Ambrettolide (4.70%). The analysis of stem revealed the presence of Formamide (CAS) Methanamide (22.48%), 12,13- Dimethyl-2,7- dioxa 5,10 diazatricyclo [4.4.4.0(1,6)] trans -tetradecan-12 (13.22%), Hexadecanoic acid (CAS) Palmitic acid (11.51%), 2-Propanone, 1-hydroxy- (CAS) Acetol (10.14%), 9-Octadecen-1-ol, (Z)- (CAS) cis-9-Octadecen-1-ol (7.09%). The analysis of roots revealed the presence of Methanamine, N-methyl- (CAS) Dimethylamine (28.45%), Acetic acid (CAS) Ethylic acid (9.78%), 3.2-Propanone, 1-hydroxy- (CAS) Acetol (6.41%), 1-Propen-2-ol, acetate (CAS) Isopropenyl acetate (5.16%), 4.73 Phenol, 2-methoxy- (CAS) Guaiacol(4.73%). The DPPH result of torbangun leaves ethanol extract obtained by IC50 247,942 ppm and ascorbic acid standard was 1 ppm. IC50 values inhibition of á-glucosidase extract was >100 ppm and glucobay standard was 0.264 ppm. This research provided a chemical compound and the torbangun leaves ethanol extract capable of acting as antioxidant based on IC50 values.Keywords: antioxidant activity, chemical compound, Coleus amboinicus LourABSTRAKPenelitian ini bertujuan untuk mengetahui komponen senyawa kimia dalam daun, dahan, dan akar menggunakan analisis Kromatografi Gas-Spektrometri Massa (GC-MS) serta aktivitas antioksidan daun torbangun (Coleus amboinicus Lour).
