从豆豆（Prosopis juliflora, Sw.）提取物中分离得到植物生长抑制生物碱。直流)树叶。通过ESI-MS、H-1和C-13核磁共振谱分析确定了它们的化学结构。对芥蓝幼苗根系生长的I-50值（抑制50%对照所需的浓度）分别为：3′-氧-朱莉素400 muM， 2′-氧-朱莉素500 muM， 3′-氧-朱莉素和3′-氧-朱莉素（1:1）混合物100 muM。另一方面，3′′-氧基朱莉素抑制幼苗生长的最小浓度为10 μ m， 2′-氧基朱莉素为100 μ m， 3′-氧基朱莉素和3′-氧基朱莉素以1:1的比例混合时为1 μ m。其中，3-o -juliprosine与3'-o -juliprosine以1:1比例混合对芥蓝幼苗生长的抑制作用最强。(C) 2004 Elsevier Ltd.版权所有。
Plant growth inhibitory alkaloids were isolated from the extract of mesquite [Prosopis juliflora (Sw.) DC] leaves. Their chemical structures were established by ESI-MS, H-1 and C-13 NMR spectra analysis. The I-50 value (concentration required for 50% inhibition of control) for root growth of cress (Lepidium sativum L.) seedlings was 400 muM for 3""-oxo-juliprosopine, 500 muM for secojuliprosopinal, and 100 muM for a (1:1) mixture of 3-oxo-juliprosine and 3'-oxo-juliprosine, respectively. On the other hand, the minimum concentration exhibiting inhibitory effect on shoot growth of cress seedlings was 10 muM for 3''"-oxo-juliprosopine, 100 muM for secojuliprosopinal, and 1 muM for a (1:1) mixture of 3-oxo-juliprosine and 3'-oxo-juliprosine, respectively. Among these compounds, a (1:1) mixture of 3-oxo-juliprosine and 3'-oxo-juliprosine exhibited the strongest inhibitory effect on the growth of cress seedlings. (C) 2004 Elsevier Ltd.
