摘要
本实验探讨赤楠果实红色素的理化性质及提取条件。结果表明,该色素属花色苷类;其最佳提取工艺是:1%HCl-乙醇(1ml HCl﹕99ml 95%乙醇)溶液作为提取剂,料液比1/10,温度35 ,提取时间3h,提取次数3次。
The physical and chemical properties of red pigment from Syzygium buxifolium fruits and the optimal extraction conditions of pigment by the orthogonal experiment were studied. The results showed that the pigment is anthocyanin, which optimal conditions of extraction were as follows: extraction agent of 1%HCL-ethanol(1ml HCl﹕99ml 95%ethanol), ratio of sample weight(g) to solvent volume(ml) 1 : 10, each extraction for three hours at 35 and by three times.
