| 摘 要： | 研究了溶剂法提取亚麻籽中木脂素的工艺,确定了单因素试验的最佳溶剂系统为70%的乙醇,提取温度为室温,时间为24 h。以木脂素得率为指标,采用二次正交旋转回归试验对溶剂法提取亚麻籽木脂素提取工艺进行优化,求得了二次正交旋转回归方程,确定了影响溶剂法木脂素得率的各因素的主次顺序依次为:提取时间、提取温度、乙醇浓度。用统计寻优方法进行方案寻优,可得乙醇浓度为70%、提取时间为28 h、提取温度为40℃时,木脂素得率最高为9.25%。

| Abstract: | The extraction technology of lignans(SDG) from flaxseed by the solvent method was investigated.The solvent for single factor tests was ethanol of 70%,extracting for 24 h at room temperature.With the recovery of lignans as experimental indexes,quadratic orthogonal regression experiments were designed,and the regressive equations concerning the experimental indexes and experimental parameters were obtained.According to the influence of experimental parameter on recovery of lignans,the order of parameters is e... |
