Abstract

Allelopathy is the interaction between donor plants and receiver plants through allelochemicals. According to a great number of publications, allelopathy may be involved in several ecological aspects such as the formation of monospecific stands and sparse understory vegetation for certain plant species. Allelopathy also contributes to the naturalization of invasive plant species in introduced ranges. Autotoxicity is a particular type of allelopathy involving certain compounds. Many medicinal plants have been reported to show relatively high allelopathic activity. We selected plant species that show high allelopathic activity and isolated allelochemicals through the bioassay-guided purification process. More than 100 allelochemicals, including novel compounds have been identified in some medicinal and invasive plants, plants forming monospecific stands, plants with sparse understory vegetation, and plants showing autotoxicity. The allelopathic activity of benzoxazinones and related compounds was also determined.

分离和鉴定等位化学物质及其活性和功能
等位反应是供体植物和受体植物之间通过等位化学物质产生的相互作用。根据大量出版物,等位效应可能涉及生态学的多个方面,如某些植物物种形成单一物种的林分和稀疏的林下植被。等位异化作用还有助于入侵植物物种在引进地的归化。自毒作用是涉及某些化合物的一种特殊的同位异化作用。据报道,许多药用植物都具有较高的等位病理活性。我们选择了具有较高等位病理活性的植物物种,并通过生物测定指导下的纯化过程分离出等位化学物质。在一些药用植物和入侵植物、形成单一物种的植物、林下植被稀疏的植物以及表现出自体毒性的植物中,我们发现了 100 多种等位化学物质,其中包括新型化合物。此外,还测定了苯并恶嗪酮类及相关化合物的等位病理学活性。
