Noni leaf extracts prevented the in vitro growth of multiple human cancer cells, including KB (human epidermoid carcinoma), HeLa (human cervical carcinoma), MCF-7 (human breast carcinoma) and HepG2 (human hepatocellular carcinoma) cell lines. Rutin and scopoletin, compounds found in noni, had modest anti-proliferative effects on the cancer cells.  Damnacanthal, another compound in noni, exhibited potent cytotoxicity against all the cancer cell lines.
