Objective To optimize the extraction of safflower yellow (SY) in Carthamus tinctorius. Methods Using the extracting rate of SY as main indicator, the content of SY in the dried and the extracting yield as reference indicators, the extracting process was studied by single factor method and orthogonal method. Results The optimum extracting procedure of SY was by 12 times of water soaking for 30 min, then decocting for 20 min and 2 times by dynamic extracting under 70 ℃. Conclusion The optimum extracting procedure could increase the content and extraction effeciency of SY from C. tinctorius.
