Abstract: 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.
