ABSTRACT OBJECTIVE To extract the effective components of Psoralea corylifolia and evaluate its efficacy in the treatment
of vitiligo. METHODS The concentrations of psoralen, isopsoralen, neobavaisoflavone, corylin, psoralidin, corylifolinin, and
bakuchiol in P. corylifolia extract were determined by ultra-performance liquid chromatography. Based on the analytic hierarchy
process (AHP) and Plackett-Burman design, with the concentrations of the 7 components as evaluation indexes and the crushing
degree, ethanol concentration, and soaking time as factors, the extraction process of P. corylifolia was optimized by Box-Behnken
response surface methodology and the validation test was conducted. Zebrafish were divided into blank control group, positive
control group (8-methoxypsoralen, 10.8 μg/mL), and low- , medium- , and high-concentration groups of P. corylifolia extract
(500, 1 000, 2 000 μg/mL), with 6 fish in each group. The effects of P. corylifolia extract on the melanin production of zebrafish
were studied by density analysis. RESULTS The best extraction process was P. corylifolia powder over 60 meshes and soaked in
80% ethanol for 72 hours. The average comprehensive score of three validation experiments was 98.27, with an RSD of 1.36%,
and the relative error was 1.02% compared with the predicted value of the fitting equation (97.28). Compared with the blank
control group, the melanin pigmentation of zebrafish in the low-, medium-, and high-concentration groups of P. corylifolia extract
was significantly increased (P<0.01). CONCLUSIONS The optimized extraction process of P. corylifolia is reasonable and
feasible, and the obtained P. corylifolia extract can significantly promote the production of melanin in zebrafish.
