ABSTRACT

This research aims to determine the cytotoxicity and antiproliferation activities of Sida rhombifolia leavesextract against cancer cells MCA-B1, A549, and normal Vero cells. Sida rhombifolia leaves were extractedwith ethanol using ultrasonication method and fractionated using n-hexane, ethyl acetate, and water. The testedsamples were ethanol extract and n-hexane fraction based on the results of cytotoxicity using the Brine ShrimpLethality Test. The antiproliferation activity test by using Trypan Blue Dye method and the cells harvested afterconfluence on the third or fourth day and the total cells were calculated by using the Neubauer Hemocytometer.The result showed that the inhibitory activity of ethanol extract at a concentration of 500 ppm is 69.44% withIC50 202.556 ppm on MCA-B1 cancer cells and 69.44% with IC50 276.836 ppm on A549 cancer cells, whilethe n-hexane fraction at a concentration of 1,000 ppm was 64.13% with IC50 425.969 ppm in MCA-B1 cancercells and 57.18% with IC50 786.617 ppm on A549 cancer cells. After being tested on normal Vero cells, theinhibition of normal Vero cells proliferation is not more than 1%. This indicates that ethanol extracts andn-hexane fraction are safe for normal cells and analysis by using LC-MS/MS showed a benzazepine compoundin the ethanol extract of S. rhombifolia is known for its role as antiproliferation. These results indicate thatS. rhombifolia leaves extract has the potential to be developed as anticancer compounds..
