摘要：

Isolation, structural elucidation and allelopathic bioassays of 13 compounds, isolated from sunflower cultivar cv. Peredovick are described. Two new sesquiterpene lactones, helivypolide D and helivypolide E and the bisnorsesquiterpene, annuionone D, which is reported at the first time as natural product, are described. The effects of a series of aqueous solutions at 10(-4)-10(-9) M of these compounds were studied on the root and shoot lengths of Lactuca sativa, Lepidium sativum seedlings (dicotyledons) and Hordeum vulgare and Allium cepa (monocotyledons), (C) 1999 Elsevier Science Ltd.
