ABSTRACT
Three pairs of enantiomers mucroniferals A-C (1-3), with a novel skeleton of 1,4-epoxynaphthalene-2,3-dicarboxylic acid first reported from nature source, were isolated from Corydalis mucronifera. Their structures were elucidated based on extensive spectroscopic data analysis of MS, 1D and 2D NMR, and their absolute configurations were confirmed by single-crystal X-ray diffraction analysis and comparison of the experimental and calculated ECD data. Mucroniferals A-C showed broad-spectrum inhibitory activities on seedling growth of all plants tested (Lepidium apetalum, Raphanus sativus, Lactuca sativa, and Arabidopsis thaliana) with a dose-dependent relationship. Additionally, mucroniferals A and B exhibited significant inhibitory effects on germination of most seeds at concentration of 80 µg/mL, and the inhibition was reversible.
