摘要
目的:研究超临界CO2萃取荷叶最佳萃取工艺及其萃取物的化学成分。方法:采用均匀设计法以萃取压力、萃取温度、萃取时间为因素,考察超临界CO2萃取荷叶的最佳萃取工艺条件并对萃取物进行GC-MS分析。结果:最佳萃取工艺为:萃取压力26 Mpa,萃取温度40℃,萃取时间90 min。并且从萃取物中分离出37个可识别峰,共鉴定26个成分,主要成分为1-乙基-1H-吡咯-2-甲醛。结论:采用均匀设计方法可以快速、准确地确定超临界CO2萃取技术萃取荷叶的最佳工艺,为荷叶进一步开发利用提供实验依据。
Objective： To study the optimum parameters of the supercritical CO2 fluid extraction of lotus leaves and chemical constituents of extractive matters. Methods： Supercritical CO2 fluid extraction condition was selected by uniform design. The extraction pressure, extraction temperature, extraction time were three factors in the experiment. GC-MS was applied for analyzising the extraction. Results： The optimum condition were obtained： the extraction pressure was 26 Mpa, the extraction temperature was 40℃, the extracion time was 90 minutes. The major constituent was ^1H-Pyrrole-2-carboxaldehyde, 1-ethyl-in extractive matters. Conclusion： Uniform design can optimize the CO2 Supercritical Fluid Extraction process quickly and accuratly with satisfactory results.
