    OBJECTIVE: To investigate the cytotoxicity and the genotoxicity of standardized aqueous of dry leaves of Erythroxylum cuneatum (E. cuneatum) in human HepG2 and WRL68 cells.

    METHODS: The cytotoxicity of E. cuneatum extract was evaluated by both MTS and LDH assays. Genotoxicity study on E. cuneatum extract was assessed by the single cell gel electrophoresis (comet assay). The protective effect of E. cuneatum against menadione-induced cytotoxicity was also investigated.

    RESULTS: Results from this study showed that E. cuneatum extract exhibited cytotoxic activities towards the cells with IC50 value of (125±12) and (125±14) μg/mL for HepG2 and WRL68 cells respectively, after 72 h incubation period as determined by MTS assay. LDH leakage was detected at (251±19) and (199.5±12.0) μg/mL for HepG2 and WRL68 respectively. Genotoxicity study results showed that treatment with E. cuneatum up to 1 mg/mL did not cause obvious DNA damage in WRL68 and HepG2 cells. Addition of E. cunaetum did not show significant protection towards menadione in WRL68 and HepG2 Cells.

    CONCLUSIONS: E. cuneatum standardized aqueous extract might be developed in order to establish new pharmacological possibilities for its application.

    Erythroxylum cuneatum (E. cuneatum) which belongs to Erythroxylaceae family is a tropical flowering plant from the genus of Erythroxylum. It is used in Malaysia and Thailand's traditional medicines, yet there is limited scientific reports on its medicinal value. This study aimed at exploring the antioxidative and anti-inflammatory properties of E. cuneatum alkaloid leaf extract. The alkaloid extract was obtained through Soxhlet heat extraction method, while the antioxidantive properties were assessed via 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging, ferric reducing antioxidant power (FRAP) and xanthine oxidase inhibition (XOI) assays. Further, anti-inflammatory property of the extract was evaluated on rat's model of carrageenan induced paw model of edema via physical measurements and histology. The extract exhibited antioxidant activity with an EC50 value of 1482 μg/ml in the DPPH radical scavenging assay, an EC1 value of 2191 μg/ml in the FRAP assay and 10.15 ± 6.20% in the XOI assay. Rats pretreated with the extract have shown dose dependent decrease in paw edema when compared to non-treated group of rats. The highest dose (50 mg/kg) of extract exhibited similar effects to aspirin in terms of reducing paw thickness, leucocytes infiltration and disruption of collagen. In conclusion, the E. cuneatum alkaloid leaf extract possesses both antioxidative and anti-inflammatory properties suggesting its potentials for future development of antioxidant and anti-inflammatory drugs.
