LEAF ARRANGEMENTS IN AILANTHUS ALTISSIMA
American Journal of Botany, 1937THE GENERAL systems of leaf arrangements are known (Wright, 1873; Henslow, 1876; de Candolle, 1881; Weisse, 1894; Strasburger, 1930; and others).

Evidence for allelopathy by tree-of-heaven (Ailanthus altissima)
Journal of Chemical Ecology, 1990Ailanthus altissima (Mill.) Swingle contains one or more phytotoxic compounds in roots and leaves. Activity is higher in roots, where it occurs primarily in the bark. Powdered root bark and leaflets strongly inhibited growth of garden cress (Lepidium sativum L.) when mixed with soil in Petri dishes (ID50 values=0.03 g root bark, 0.6 g leaflet/dish ...

Antiproliferative effects of tree-of-heaven (Ailanthus altissima Swingle)
Phytotherapy Research, 2005Tree-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 ...
