Abstract:
The extracts prepared from Liriodendron tulipifera Linn., L. chinense (Hemsl.) Sarg., and their hybrid L. chinense x L. tulipifera, were investigated for their cytotoxic abilities in vitro against five human cancer cell lines: MDA-MB-231 and MCF-7 breast cancer cells, SGC-7901 gastric cancer cells, HuH-7 hepatocarcinoma cells, and HCT-15 colon carcinoma cells, and then measured their phenols and alkaloids contents. Of these plant extracts, some of them, especially the lower polar extracts from barks, exhibited potent cytotoxic effects on five tested tumor cell lines.
