吉祥草的化学成分研究

Chemical constituents in aerial part of Reineckea carnea

目的：对吉祥草的化学成分进行研究。方法：利用萃取，硅胶、凝胶和反相硅胶柱色谱以及高效液相色谱法进行分离和纯化，采用谱学技术（1D和2D NMR谱，MS，IR等）进行结构鉴定。结果：从吉祥草中分离鉴定了6个化合物，分别是1α，3β-dihydroxy-5β-pregn-16-en-20-one 3-O-β-D-glucopyranoside（1），syringaresinol-β-D-gluco-side（2），sophoraflavoneB（3），stigmast-5，22-dien-3-O-β-D-glucopyranoside（4），胡萝卜苷（5），α-D-glucose（6）。结论：化合物1为新化合物，化合物2～6为首次从该植物中分离得到。

Objective： To study the chemical constituents in the aerial part of Reineckea carnea. Method： The compounds were isolated by extraction, silica gel, gel, and reversed-phase silica gel coloum chromatography, and high-performance liquid chromatography. The structures were identified by various spectroscopic methods including 1D and 2D NMR spectrum, MS, IR, etc. Result： Six compounds were isolated and identified as 1α,3β-dihydroxy-5β-pregn-16-en-20-one 3-O-β-D-glucopyranosideide（1）, syringaresinol-β-D-glucoside （2） , sophoraflavone B （3） , stigmast-5, 22-dien-3-O-β-D-glucopyranoside （4）, daucosterol （5）, α-D-glucose （6）. Conclusion： Compound 1 was a new compound, coumpounds 2-6 were obtained from the plant for the first time.
