摘　　要：以废弃紫荆花为原料,研究微波与表面活性剂水溶液协同提取紫荆花红色素,确定十二醇硫酸酯钠盐(K12)为紫荆花红色素提取的最佳表面活性剂,通过正交实验确定了最佳协同提取条件为:微波辐射档数:中高火,提取时间:50s,十二醇硫酸酯钠溶液浓度:0.03%,提取固液料比:1∶80g/mL。对比实验结果表明,采用该法使紫荆花红色素的提取率比仅用微波法提高11.6%。A procedure to extract the red natural pigment from the flower of Bauhi nia aurea Levl was discussed. The optimum conditions for extraction of the pigme nt were established as follows:K12 was the appropriate surfactant for extraction and its suitable consistency was about 0.03%, the extracted power was middle an d high radiation, the time was 50 seconds and the extracted solvent was 1:80 g/m L. Combining microwave-assistant technology with dissolution character of surfac tants, the extractive proportion of the pigment was 11.6% higher than only using the microwave-assistant technology.
