摘要:

利用响应面分析法对仙人掌中黄酮类物质的提取工艺进行优化。先通过单因素试验,然后选取适当的试验因素与水平,根据中心组合试验设计,采用四因素三水平响应面分析法,对各个因素的显著性和交互作用进行分析。结果表明:仙人掌黄酮醇提工艺的最佳条件为液料比20:1(mL/g)、浸提温度52.5℃、浸提时间4h、乙醇体积分数85%,在该条件下测得的仙人掌黄酮最大提取率为0.784%。

Abstract:

Response surface methodology was used to optimize the extraction processing of cactus flavonoids according to central composite design principle based on the single factor experimental results. Through screening of factors and levels, and the analysis of cross-interaction among factors, the optimal extraction conditions for cactus flavonoids were material-liquid ratio of 1:20, extraction temperature of 52.5 ℃, extraction time of 4 h, and alcohol concentration of 85%. The extraction rate of flavonoids was 0.784% under the optimal extraction conditions.

Key words: cactus, flavonoids, extraction, response surface methodology
