Abstract / 摘要


This study introduced a method to continuously collect allelopathic compounds from the intact root system of Bigalta limpograss using a nutrient solution circulated through a column containing XAD-4 resin. The method enabled the identification of 12 primary phenolic compounds with growth-regulating activities.
本研究提出了一种新的方法,通过将营养溶液循环通过含有XAD-4树脂的柱子,连续收集未受干扰的Bigalta草丛根系中的化感化合物。该方法能够有效地收集植物根系分泌的代谢产物,并避免土壤中的高污染水平干扰。研究识别了12种主要的酚类化合物,这些化合物具有已知的生长调节活性。

Methods / 方法


1. Culture Method: Using a sand culture system with Bigalta limpograss.
1. 培养方法: 使用含有Bigalta草丛的沙培系统。
2. Collection System: Nutrient solution circulated through the root system and XAD-4 resin column to adsorb hydrophobic metabolites from the root exudates.
2. 收集系统: 营养溶液循环通过根系和XAD-4树脂柱,吸附根系分泌的疏水代谢物。
3. Separation and Analysis: Eluted the resin with methanol and separated the compounds using paper and thin-layer chromatography. Identified the compounds using gas chromatography-mass spectrometry (GC-MS).
3. 分离和分析: 使用甲醇洗脱树脂,并通过纸层析和薄层层析分离化合物。使用气相色谱-质谱联用技术(GC-MS)进行鉴定。

Results / 结果


1. Identified 12 phenolic compounds, including 3-hydroxycinnamic acid, benzoic acid, phenylacetic acid, and cinnamic acid.
1. 鉴定出12种酚类化合物,其中包括3-羟基肉桂酸、苯甲酸、苯乙酸和肉桂酸。
2. The method is more efficient compared to the traditional solvent extraction method and is suitable for a wide range of studies on rhizosphere chemistry.
2. 方法相比传统溶剂提取法更为高效,适用于根际化学方面的广泛研究。
