Evaluation of Anticancer Action of Martynia annua Linn Root Extract on Different Human Cancer Cell Lines

Abstract

Background: In the last few decades, plants have been playing a vital role in treating cancer and infectious diseases. Natural products have been rediscovered as effective methods of drug production amid advances in combinatorial chemistry. Roots of Martynia annua are being used as a folklore remedy for the treatment of cancer and rheumatism successfully. Aims of the Study: In the present study, ethanolic, aqueous and hydro-ethanolic root extracts of Martynia annua were screened for in vitro cytotoxicity activity using different cell lines. Settings and Design: In the experiment, lung cancer cell lines (A549), leukemia cancer cell lines (K562), oral cancer cell lines (SCC-40), breast cancer cell lines (MCF-7) & cervix cancer cell lines (SiHa) were studied on the extracts. Materials and Methods: The method used was Sulforhodamine B (SRB) assay technique in which growth inhibition of 50% (GI50) was analyzed by comparing it with standard drug Adriamycin (ADR) (doxorubicin). Results: Aqueous & ethanolic extract of Martynia annua root had shown high anticancer activity with GI50 value 11.3µg/ml and 20.4µg/ml respectively on human leukemia cell line K-562 but for human breast cancer cell line MCF-7, human lung cancer cell line A-549, human squamous cell carcinoma SCC-40 and human cervical cancer cell line SiHa the extracts showed activity in more than 80µg/ml. Conclusion: The anticancer activity of aqueous extract of Martynia annua root was found superior than the ethanolic extract in Human Leukemia Cell Line K-562. The study indicates that the Martynia annua root extracts are most effective against the fast proliferative cells (Leukemic cells) and possibly a cell cycle arrest (needed to be proved as future perspective) is the mode of action of the extract. To study its effect on targeted cancers, specific in vivo scientific studies and clinical trials should be carried out by further researchers.
