ABSTRACT:     Trikanrapit (red basil roots, galangal rhizome, and fingerroot) is a traditional Thai herbal remedy used to cure body impairment, nourish blood and sexual desire, and as a carminative drug. This study aimed to investigate the antioxidant activity via 2,2-Diphenyl-1-picrylhydrazyl (DPPH) radical scavenging (DPPH), 2,2? - azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical cation decolorization (ABTS), ferric ion reducing antioxidant power (FRAP) assay and cytotoxic activity via a sulforhodamine B assay. The chemical constituents of the extracts were analyzed using gas chromatography-mass spectrometry (GC-MS). The results indicate that the ethanolic extract of Trikanrapit remedy showed good antioxidant activity, and the root extract of Ocimum tenuiflorum, one of the three herb constituents, exhibited strong antioxidant activity on the DPPH and ABTS?+ assays. The Trikanrapit remedy extract showed moderate cytotoxicity against LS174T colorectal adenocarcinoma cells and human lung adenocarcinoma A549 cells, with 50% maximal inhibitory concentration (IC50) values of 52.04 and 46.85 ?g/ml, respectively. While the root extract of O. tenuiflorum showed high cytotoxicity activities on both the LS174T and A549 cell lines, with IC50 values of 31.51 and 29.60 ?g/ml, respectively. Moreover, Trikanrapit extract contains approximately 47 different compounds. In addition, the data discussed in this study revealed cytotoxic and antioxidant properties, which correspond to the traditional Thai theory of using herbal recipes to treat various diseases.
