Abstract:
Objective To multi-objectively optimize the purification process parameters of Yinju Jiedu Oral Liquid (YJOL), mixed weight of AHP-CRITIC, Plackett-Burman design (PBD), and Box-Behnken design (BBD) were adopted on the basis of HPLC fingerprints. Methods HPLC was used to establish HPLC fingerprint of YJOL. Recovery rate of fingerprints of six components (chlorogenic acid, linarin, harpagoside, R,S-epigoitrin, psoralen, and isobalin) and HPLC fingerprint similarity was taken as the index to optimize the type of macroporous resin among 10 types. Weights of the recovery rates of six components and similarity were determined by mixed weight of AHP-CRITIC, in order to obtain the comprehensive index as the evaluation criterion. The significantly influencing factors were firstly evaluated by PBD, and purification conditions were optimized by BBD. Results HPD-400 type resin showed a high selectivity for six components. The optimized purification technology was as follows: the ratio of dia-height was 1:7, pH value was 3.5, sample concentration was 0.18 g/mL, ratio of sample to resin was 0.96 g/g, and 77% ethanol's dosage was 8 BV. Under the conditions, the recovery rates of six components were 78%-98%, and the similarity of fingerprint was higher than 0.99. These components could get balanced recovery. Moreover, the theoretical and actual comprehensive indexes were 94.28% and 93.69%, respectively, with a relative error of 0.59%. Conclusion Based on HPLC fingerprints, mixed weight of AHP-CRITIC, combined with PBD and BBD-RSM used to optimize the purification process for the YJOL in this study is scientific and feasible, this way can improve the purity of the active components and keep the uniformity of main components in the YJOL as well.
