Plants release any chemical compounds, allelopathic substances, affect the plant growth or fungal growth etc. It has been reported that germinating sunflower seeds have a species-selective allelopathic function, and an allelopathic substance, 4, 15-dinor-3-hydroxy-1(5)-xanthene-12, 8-olide(sundiversifolide), was isolated and identified from the exudates of germinating sunflower seeds. We have also purified some substances, which may relate to allelopathic activity in sunflower seeds. Some of these substances promoted the growth of other species of plants and some substances of them inhibited it of them. The amount of sundiversifolide extracted from the exudates was very little. It has been suggested that some substances related to inhibitory activity occurred in the exudates. In this study, we investigated the property as allelopathic substances of fractionated or isolated substance(s) released from sunflower seeds on the contribution to allelopathy.
