Supplementary Material: To assess the cytotoxic effects of aqueous(AAA) and ethanolic(EAA) extracts of Achyranthes Aspera Root on human colon cancer cells (COLO-205) various assays were carried out.

The results revealed that both the extracts were able to reduce the viability in a dose dependent manner although AAA had more pronounced effects (Figure S1).These results were qualitatively verified by AO/EB(Figure S2) and Annexin V/PI(Figure S3) staining which revealed the ability of both the extracts to induce apoptosis in the COLO-205 cells, whereas the untreated cells showed no evidence of apoptosis.

The data generated revealed that in comparison to EAA, AAA showed more promise in terms of eliciting cell death. Therefore this extract was pre-treated with β-glucosidase to mimic in vivo conditions and it was seen that enhanced cytotoxicity to the COLO-205 was observed as compared to the extract in which no pre-treatment with the enzyme had been carried out(S4). These results indicated that the AAA could be modified by enzymes present in vivo leading to greater toxicity to the cancer cells.

Finally GC-MS analysis of AAA revealed the presence of 10 biological compounds which could be responsible for the various effects seen on COLO-205 cells (S5).
