Optimization of Extraction Process of Ruyi Gel Plaster by AHP-CRITIC Combined with Orthogonal Test
Objective To optimize the extraction process of Ruyi Gel Plaster.Methods The geniposide content,baicalin content and dry extract yield were taken as the evaluation indicators,the analytic hierarchy process(AHP)-CRITIC method was used to determine their weight coefficients.The orthogonal test was used to optimize the extraction process of Ruyi Gel Plaster with the water addition amount,soaking time and extraction time as the investigation factors.Then the verification test was carried out.Results The optimal process was as follows:adding 12 times the amount of water for the first time,extracting for 2.0 h;adding 10 times the amount of water for the second time,extracting for 1.5 h.Based on the optimal extraction process,the dry extract yield,geniposide content and baicalin content of the samples were in the range of 24.11%-24.23%,2.20-2.25 mg/g and 12.10-12.15 mg/g,respectively.Conclusion The optimal extraction process is scientific and reasonable,which can provide a basis for the follow-up research and development of Ruyi Gel Plaster.
