【摘要】 目的对红花黄色素的提取工艺进行优化。方法采用单因素试验法和正交试验法,以红花黄色素的提取率为主要考察指标,以红花黄色素在固形物中的质量分数及总出膏率为参考指标,对提取工艺进行考察。结果红花黄色素的最佳提取工艺:以12倍量水浸泡30min,70℃下动态提取2次,每次20min。结论该工艺可提高红花中红花黄色素的提取率。更多还原

【Abstract】 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.更多还原
