摘要:目的:采用近红外光谱(NIR)技术对大青叶中的有效成分靛玉红的提取分离工艺进行研究。方法:采用氧化铝柱色谱法分离靛玉红,氯仿-醋酸乙酯作为洗脱剂,洗脱液用甲醇-丙酮重结晶。结果:此工艺所得靛玉红纯度为97.78%,且样品与对照品纯度相接近,NMR和IR图谱相同。结论:该法简便易行,安全、成本低、方便,实验结果良好。
AIM : To study the suitable conditions of the extraction-separation process of the indirubin in Folium Isatidis with NIR. METHODS: The indirubin was chromatographed on an aluminium oxide column and chloroform-ethyl acetate as eluting agent, eluate was recrystalized by methanol-acetone. RESULTS: The indirubin extracted by this method was of high purity (97.78%). The sample purity was similar to reference substance one (98.01%). The spectra of NMR and IR are the same. CONCLUSION: This method is proved to be fast, safe, lower cost, simple and has good results.
