Effect of various bioactive compounds such as a ascorbic acid, b catechin, c methyl gallate, d reserpine, e rutin and f tannic acid present in ETME on cell viability and growth of A549, MCF-7 and WI-38 cells using WST-1 assay. Results were expressed as cell viability (% of control). All data is expressed as mean ± SD (n = 6). *p < 0.05, **p < 0.01 and ***p < 0.001 vs. 0 µg/ml
