摘要

目的:优化超临界CO2萃取穗花大黄中总蒽醌的工艺条件。方法:以萃取压力、萃取温度和萃取时间为考察因素

采用紫外-可见分光光度法测定总蒽醌含量

以大黄萃取物中总蒽醌的含量为评价指标

正交试验优选工艺条件。结果:最佳工艺条件为萃取压力25 MPa

萃取温度50℃

萃取2.0 h。提取物中总蒽醌的质量分数23.4 mg.g-1

总蒽醌转移率达91.4%。结论:该工艺稳定可行

可用于穗花大黄总蒽醌的提取。

Abstract

Objective: To optimize extraction process conditions of total anthraquinones from Rheum spiciforme by supercritical CO2.Method:With extraction pressure

extraction temperature and extraction time as factors

the content of total anthraquinones from extract of R.spiciforme as index

the content of total anthraquinones was determined by UV-visible spectrophotometry

technology conditions were optimized by orthogonal test.Result:Optimum technology conditions were as follows:extraction pressure was 25 MPa

extraction temperature was 50 ℃

extracted 2.0 h.The content of total anthraquinones in extract was 23.4 mg·g-1

transfer rate was up to 91.4%.Conclusion:This process was stable and feasible

it could be used to extracting total anthraquinones from R.spiciforme.
