石龙芮化学成分研究

Chemical Constituents in Herb of Ranunculus Sceleratus

摘要:

目的: 对石龙芮Ranunculus sceleratus的化学成分进行分离鉴定。 方法: 采用各种色谱方法分离,运用多种波谱技术鉴定结构。 结果: 从石龙芮中分离鉴定了5个化合物,分别为正十六烷酸(hexadecanoic acid,1 )、β-谷甾醇(β-stiosterol,2 )、1-二十二烯(1-docosene,3 )、(3β,24S)-豆甾-5-烯-3-醇((3β,24S)-stigmast-5-en-3-ol,4)、大黄素(Emodin,5)。 结论: 化合物3~5 为首次从该植物中分离得到,化合物5 为首次从该属分离得到。

Abstract:

Objective: To isolate and determine the chemical constituents of Ranunculus sceleratus. Method: The column chromatographic techniques were applied to isolate the constituents. Result: The spectroscopy methods were used of EI-MS and NMR to identify the structures of the separated compounds. Five compounds were isolated from R. sceleratus and their structures were elucidated. Conclusion: Compound 3-5 were isolated for the first time from this plant and 5 was isolated for the first time from the genus.
