- 摘要:
- 为比较微波提取与乙醇提取黄酮类物质的优缺点,优化微波提取黄酮类物质的方法，使用不同浓度的乙醇，提取太和香椿黄酮类成分，考察影响微波萃取的各个因素，研究不同提取温度、微波频率、萃取溶剂（椰子油脂肪酸二乙醇酞胺，别名尼纳尔）、样品基质等对太和香椿中黄酮类成分含量的影响，确定最佳萃取方案。结果表明：乙醇提取的最佳条件为乙醇体积分数为80%，沉淀10 h；微波提取0.8%质量分数尼纳尔溶液为萃取液，在微波功率为360 W时，微波提取8 min，得到提取液中黄酮类物质浓度最大。微波提取黄酮类物质相比于有机溶剂提取具有提取率高、产品纯度高、能耗小、操作费用少等优点。
- Abstract:
- In order to compare the advantages and disadvantages of microwave extraction and ethanol extraction of flavonoids,optimization of microwave extraction of flavonoids.Different concentrations of ethanol were used to extract Taihe toon flavonoids.The impact of various factors of microwave extraction was investigated,the effect of different extraction temperature,microwave frequency,the extraction solvent (coconut oil fatty acid diethanol Thalidomide,Ninaer),the sample matrix and other ingredients of flavonoids in Taihe toon were studied,and the most good extraction program was determined.The results showed that the optimal conditions for the extraction of ethanol was ethanol volume fraction of 80%,precipitation 10 h; microwave extraction 0.8% mass fraction Nina Er solution to extract,in the microwave power of 360 W,microwave extraction for 8 min,then an extract the maximum concentration of flavonoids was obtained.The microwave xtraction of flavonoids had a high extraction rate,high product purity,low energy consumption,low operating cost advantages compared with organic solvent extraction.
