摘要:

为了探索花生根白藜芦醇提取的最佳条件,在单因素试验的基础上,应用响应面法优化花生根白藜芦醇的提取条件。结果表明:乙醇浓度、提取温度和提取时间对花生根白藜芦醇的提取效果有显著影响,且为非线性关系,最佳提取条件为乙醇浓度65%、提取温度52℃、提取时间39min,在此条件下白藜芦醇的提取率为0.012%。实验证明响应面法对花生根白藜芦醇提取条件的优化是可行的,得到的白藜芦醇提取条件具有实际应用价值。

Abstract:

To optimize the extraction technology of resveratrol from peanut root, response surface methodology was applied on the basis of single factor tests. The results showed that ethanol concentration, temperature and extraction time significantly affect the resveratrol extraction, and after optimization, they are 65%, 52 ℃ and 39 min, respectively. Under these conditions, the resveratrol yield is 0.012%. In conclusion, the optimization of extraction technology of resveratrol from peanut foot by response surface methodology is feasible, and the extraction technology has practical application value.

Key words: resveratrol, peanut root, extraction, response surface methodology
