摘要
本文利用SFE-CO2(超临界CO2)萃取芦笋中的活性物质,探讨了萃取压力、温度、时间等对萃取率的影响。通过正交试验确定最佳萃取工艺条件为:萃取压力30MPa,萃取温度75℃,萃取时间1h。并对提取物进行了H P L C、M S分析。结果显示:分离物中以类黄酮物质(芦丁)为主。
Extracting the active substances from asparagus with SFE ,the paper investigated the effects of pressure、 temperature、time on extraction. According to orthogonal test, the optimum extraction conditions were obtained as follows: P=30MPa, T=75℃, t=1h. After the analysis on the extracting substances with HPLC / MS, the results showed that: Rutin of flavonoids was the main component of the extracts.
