Abstract

New plant growth regulators, named brevicompanine C (1), cyclo-(D-Ile-L-Trp) (2), and cyclo-(D-Leu-L-Trp) (3), have been isolated from Penicillium brevi-compactum Dierckx, and their structures have been established by spectroscopic methods including 2D NMR and chiral TLC analysis. Plant growth activities of 1, 2, and 3 have been examined using lettuce seedling bioassay methods. All compounds accelerated the root growth of the seedlings in proportion to their concentration from 1 to 100 mg/L.

摘要

从短密青霉中分离出了新的植物生长调节剂，分别命名为短密青霉碱C（1）、环（D-异亮氨酸-L-色氨酸）（2）和环（D-亮氨酸-L-色氨酸）（3），并通过包括二维核磁共振和手性薄层色谱分析在内的光谱方法确定了它们的结构。使用生菜幼苗生物测定法检测了1、2和3的植物生长活性。所有化合物在1至100毫克/升的浓度范围内，均按比例促进了幼苗的根系生长。
