The root extract of Eurycoma longifolia Jack has been shown to be effective against different type of cancers. Present study was carried out to study the effect of three biotic elicitors, yeast extract, pectin, and valine, on the cytotoxicity activity of the bioactive compounds produced in the cell suspension culture of E. longifolia against human colon cancer cell lines. Yeast extract consists of vitamin B complex, chitin, N-acetyl-glucosamin, β-glucan, glycopeptide, and ergosterol, while pectin contains cell wall components. Yeast extract and pectin, along with the branched chain amino acid valine, were evaluated as biotic elicitors to trigger the production of plant defense–related compounds. The different stages of cell growth influenced the production of the bioactive compounds; hence the administration of the elicitors at different stage of cell growth is vital for enhancement of their production. The results showed that all three biotic elicitors were effective in enhancing cytotoxic activity similar to that of root extract from the mature plant against human colon cancer cell line, HCT116, without affecting its cell growth. Crude extract derived from cells elicited with 2.0 g L−1 pectin supplemented on the 17th d showed good inhibition of HCT116 cell proliferation with IC50 of 19.4 μg mL−1. Hence, cell suspension culture of E. longifolia with elicitation is an alternative time-saving tool for production of valuable anti-cancer compounds and the conservation of this valuable plant due to indiscriminate harvesting from its natural habitat.
