摘要： 采用加压技术提取菊花中黄酮类成分,在单因素试验的基础上,利用正交法优化菊花中黄酮类成分的提取工艺,并研究加压提取技术对菊花中黄酮类成分的抗氧化活性的影响。结果表明,采用 60% 的乙醇,在 70℃、料液比1:60(g:mL)、压力 0.25 MPa 下,加压提取 40 min,得率为 8.07%;同时,与回流提取法相比,加压提取法对菊花中黄酮类成分的抗氧化活性没有影响。

Abstract: Flavonoids were extracted from the Chrysanthemum monfolium Ramat by pressurized liquid extraction. Conditions including extraction temperature, ratio of material to liquid, the ethanol concentration, extraction time, and extraction pressure were studied by using single factor analysis method. The optimal process conditions were obtained by orthogonal analysis as follows: the extraction temperature 70℃, ratio of material to liquid 1:60, the ethanol concentration 60%, extraction time 40 min and extraction pressure 0.25 MPa. The yield of extraction was 8.07﹪. Compared with the flavonoids extracted by traditional refluxing extraction, the flavonoids extracted by the pressurized liquid extraction had a similar elimination function on DPPH·radical with the traditional refluxing extraction.

Key words: Chrysanthemum monfolium Ramat, flavonoid, pressurized liquid extraction, anti-oxidation
