Objective To optimize the feasible technique on extracting ferulic acid and hydrosafflower yellow A from Shuxiong Tablets by microwave-assisted extraction and compare the extract yield with the conventional extraction.Methods Taking the extract yield of ferulic acid and hydrosafflower yellow A as indexes,microwave-assisted extraction of Shuxiong Tablets was investigated by uniform design.Results Some parameters,such as the microwave power,radiation time,and solvent consumption had the interactions on the extraction of ferulic acid and hydrosafflower yellow A,the optimal technique parameters of extracting chuanxiong and safflower were 790 W as the microwave power,30 and 24 min as the extracting time,1∶24 and 1∶22 as the ratios of raw material to solvent,respectively.Conclusion The microwave assisted extraction is found to be convenient and rapid for Shuxiong Tablets with short time and high yield.
