摘要: 采用索氏提取法比较了不同溶剂对月季花红色素的提取效果,得出95%乙醇为最佳溶剂。95%乙醇提取液λmax为524nm。单因素试验和正交试验结果表明:提取温度和料液比对月季花红色素的提取效果影响较大,其次为提取时间,而粒度的影响较小。最佳提取工艺条件为:溶剂为95%乙醇,月季花粉末的粒度为60目,料液比为1:40(g/ml),提取温度为91℃,提取时间为6h。按此工艺提取,测得月季花红色素的产量为49.02%。

Abstract: The Soxhlet extraction effects of Chinese rose flower red pigment with different solvents were compared. The results showed that 95% ethanol is the optimum solvent. The maximum absorption wavelength of the 95% ethanol solution is 524 nm. The single factor test and orthogonal test results showed that ratio of meterial to solvent and extraction temperature have greater effects on extraction of the pigment,followed by extraction time and particle size of flower powder in turn. The optimal extraction conditions are as follows:Particle size of flower powder 60 mesh,ratio of material to solvent 1:40,extraction temperature 91℃,and extraction time 6 h. Under the optimal extraction conditions,the yield of Chinese rose flower red pigment is 49.02%.
