Extraction of effective components of Psoralea corylifolia and efficacy evaluation in the treatment of vitiligo
and evaluate its efficacy in the treatment of vitiligo.
METHODS
2
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
2
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
2
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.
