Antiproliferative effects of tree-of-heaven (Ailanthus altissima Swingle)

Phytotherapy Research, 2005
Tree-of-heaven (Ailanthus altissima Swingle) was evaluated for its cytotoxic and antiproliferative activities by a bioassay-oriented study. Cytotoxicity observed in HeLa cells was time-dependent; the treatment with 10 microg/mL of the root chloroform extract reduced cell viability by 56% at 24 h and 29% at 48 h of exposure, whereas no effect was ...
