Corydalis Rhizoma is a commonly used traditional Chinese medicine(TCM) for regulating Qi and relieving pain in clinical practice, with remarkable efficacy. However, its pharmacodynamic substances are not yet fully understood and require further research. In this study, 24 compounds were isolated and identified from the aqueous extracts of vinegar-processed Corydalis Rhizoma using techniques such as macroporous adsorption resin column chromatography, Sephadex LH-20 column chromatography, and semi-preparative high-performance liquid chromatography. Their structures were determined based on their physicochemical properties and spectroscopic methods, including UV, IR, HR-MS, 1D NMR, and 2D NMR. Among these, compounds 1 and 2 are two rare natural α-carbonamide alkaloids, named yanhuoxamide A(compound 1) and yanhuoxamide B(compound 2), respectively. Compounds 3-24 are known compounds, identified as xanthoplanine(3), stigmast-4-ene-3,6-dione(4), norchelerythrine(5), ethyl ferulate(6), 6-hydroxymethyl-3-pyridinol(7), 6-(\[1,3\]dioxolo\[4,5-g\]isoquinoline-5-carbonyl)-2,3-dimethoxy-benzoic acid methyl ester(8), 1H-indole-3-carbaldehyde(9), 4-hydroxy-3-methoxy ethyl cinnamate(10), berberal(11), oblongine trifluoroacetate(12), thalbaicalidine(13), cyclopiamide(14), nicotinamide(15), dehydrocorypalline trifluoroacetate(16), 6-acetonyldihydrochelerythrine(17), 6-acetonyldihydrosanguinarine(18), norsanguinarine(19), oxysanguinarine(20), bulbocapnine(21), corydine(22),(-)-(13aS)-stylopine(23), and(-)-(9S,13S)-pallidine(24). Among these, compounds 3-15 were isolated from the genus Corydalis for the first time, and compounds 16-24 were isolated from Corydalis Rhizoma for the first time. Additionally, the inhibitory activity of compounds 1 and 2 on acetylcholinesterase(AChE) was evaluated. |
