Abstract

Natural red pigment is directly extracted from natural Pyracantha fortuneana fruit by acidity ethanol.It discussed some factors,the ratio of sample to solvent,extraction time,extraction times and extraction temperature etc,how to influence the extraction of red pigment from Pyracantha fortuneana fruit.The best parameters of extraction technology were determined through orthogonal experiment L_9(3~4).The results showed that the optimal conditions are as follows:the ratio of sample to solvent is 1 ∶9,extraction time 40 minutes,extraction 4 times and extraction temperature 40℃.Extraction rate is 93.5%,produce rate is 20%.
