女贞果天然红色素提取条件研究

Study on the Conditions of Drawing Out Natural Red Pigment from Fructus Ligustri Lucidi

用正交实验探讨女贞果天然红色素的最佳提取工艺条件,研究结果表明:70℃条件下,用25倍于果皮重的水回流2次,时间为2h/1.

The optimum extracting conditions of natural red pigment in fructus ligustri lucidi were investigated by using orthogonal desingn. The results showed that 70℃,25∶1 of water to fructus ligustri lucidi weight ratio,extracted two times during 2h/1.5h were optimal.
