Abstract

Plant growth inhibitory alkaloids were isolated from the extract of mesquite [Prosopis juliflora (Sw.) DC.] leaves. Their chemical structures were established by ESI-MS, 1H and 13C NMR spectra analysis. The I50 value (concentration required for 50% inhibition of control) for root growth of cress (Lepidium sativum L.) seedlings was 400 microM for 3''''-oxo-juliprosopine, 500 microM for secojuliprosopinal, and 100 microM 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 microM for 3''''-oxo-juliprosopine, 100 microM for secojuliprosopinal, and 1 microM 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.

摘要

从牧豆树（牧豆树）的叶子提取物中分离出了抑制植物生长的生物碱。通过电喷雾质谱、1H和13C核磁共振光谱分析确定了它们的化学结构。水芹（独行菜）幼苗根生长的I50值（抑制对照生长50%所需的浓度），对于3'''' - 氧代朱利普罗索平为400微摩尔，对于裂朱利普罗索平为500微摩尔，对于3 - 氧代朱利普罗辛和3'-氧代朱利普罗辛的（1:1）混合物为100微摩尔。另一方面，对水芹幼苗地上部分生长表现出抑制作用的最低浓度，对于3'''' - 氧代朱利普罗索平为10微摩尔，对于裂朱利普罗索平为100微摩尔，对于3 - 氧代朱利普罗辛和3'-氧代朱利普罗辛的（1:1）混合物为1微摩尔。在这些化合物中，3 - 氧代朱利普罗辛和3'-氧代朱利普罗辛的（1:1）混合物对水芹幼苗的生长表现出最强的抑制作用。
