Abstract The present study describes the antioxidant effect, glucose uptake activity and cytotoxicity of Melicope lunu-ankenda (ML) leaf extract using cell lines. Results of the study revealed that 60% ethanolic ML extract demonstrated the highest antioxidant activity with total phenolics and flavonoid contents of 354 mg GAE/g DW and 313 mg rutin equivalent (RE)/g DW, respectively. Ferric reducing antioxidant power (FRAP) was found to be 294.3 mM Fe (II) /g. The study showed that, ML leaf extract stimulated fluorescent d-glucose analog 2-[N-(7-nitrobenz-2-oxa-1, 3-diazol-4-yl) amino]-2-deoxy-d-glucose (2-NBDG) uptakes by both 3t3-L1 adipocytes and HepG2 hepatocarcinoma cells, showing significant increase in a dose dependent way. Interestingly, cytotoxic activity of the extract conducted against 3t3-L1 adipocytes and HepG2 using the 3-(4, 5-Dimethylthiazol-2-yl)-2, 5-diphenyl tetrazolium bromide (MTT) assay, showed high activity against HepG2 hepatocarcinoma cells with IC 50 of 20.33 ± 1.5 μg/mL and 13.7 ± 2.1 μg/mL after exposure of 48 h and 72 h, respectively. However, ML extract was inactive against 3t3-L1 cell line with IC 50 values of 93 ± 3 μg/mL and 81 ± 2 μg/mL. The results ascertained the significance of ML as a medicinal plant with prodigious applications as an anti-diabetic as well as anti-cancer agent. [ABSTRACT FROM AUTHOR] |
