摘要：

Root exudates from Acroptilon repens (Russian knapweed) were found to be phytotoxic and the phytotoxin in the exudate was identified as 7,8-benzoflavone (alpha-naphthoflavone), (1), not previously known as a natural product. In tests on growing seedlings both 1 and its isomer 5,6-benzoflavone (2) were phytotoxic. Flavone, a structural analog of 1 and a known granular leaf and stern exudate of other plant species, was also phytotoxic and more potent than 1 or 2. (C) 2003 Elsevier Ltd. All rights reserved.
