Abstract: The aim is to provide an efficient method for extracting anthocyanins from purple wheat bran using CTAB experiments, the antioxidant activities and wool dyeing of anthocyanins extracted from purple wheat bran were detected. The results indicated that the best parameters of extraction were solid-liquid ratio 1:3, extraction time 60 min and 3 extraction times, and the yield was 3.20 g/kg. UV absorption spectroscopy and atomic absorption spectrometry showed that anthocyanins from purple wheat bran had high color value (170) and low heavy metal content. Antioxidant experiments showed that the anthocyanins from purple wheat bran had strong scavenging capabilities for H2O2, with the value of IC50 as 1.52. Moreover, the anthocyanins were successfully applied to wool dyeing. In conclusion, the method has high potential for anthocyanins extraction from purple wheat bran.
