目的研究克感利咽口服液处方4味药材超临界萃取的最佳方法。方法分别以萃取率、薄荷醇萃取量作为指标,通过正交试验、气相色谱测定、SAS统计分析,研究超临界萃取工艺。结果试验工艺水平范围内,温度和时间对萃取率和薄荷醇萃取量都有显著影响,压力对萃取率和薄荷醇萃取量都无显著影响;影响萃取的超临界萃取较优工艺为温度55℃,时间150min,压力27MPa;影响薄荷醇萃取量的超临界萃取较优工艺为温度45℃,时间150min,压力22MPa。结论克感利咽口服液原料超临界萃取是可行的。

Objective To optimize supercritical extraction technique from four medicinal materials, which are the part components in the recipe of Keganliyan Oral Liquor and are extracted traditionally for essential oils. Methods Extraction ratio and menthol extraction quantity were taken as evaluated indexes. Supercritical extraction technique was researched with orthogonal tests, gas chromatography, and SAS statistic. Results Within the test levels, temperature and time showed evident effect on extraction ratio and menthol extraction quantity, while pressure did not show any evident effect on them、 The preferable technique to extraction ratio is temperature at 55 ℃, time for 120 min, and extracted pressure at 27 MPa; and the preferable technique to menthol extraction quantity is temperature at 45 ℃, time for 120 min, and extracted pressure at 22 MPa. Conclusion The optimized supercritical extraction technique for Keganliyan Oral Liquor is feasible.
