Identification of Plant Growth Inhibitory Principles in Ailanthus altissima and Castela tortuosa

Journal of Agricultural and Food Chemistry, 1995
A methanol extract of Ailanthus altissima and a methylene chloride extract of Castela tortuosa exhibited plant growth inhibitory activity against Brassica juncea, Eragrostis tef, and Lemna minor. Ailanthone and chaparrinone were identified as the active constituents in A. altissima and C. tortuosa, respectively. In the bioassays with B. juncea, E. tef,
