- Abstract: To study the pharmacokinetics of three active ingredients in Qing'e wan, namely geniposidic acid, psoralen and isopsoralen, in rats, in order to investigate their correlation in the anti-osteoporotic effect. The rats were taken blood from their eye sockets at different time points after being orally administered with raw and salt-processed Qing'e wan. Geniposidic acid, psoralen and isopsoralen in rats plasma were determined by means of UHPLC-MS/MS to draw the concentration-time curve. The proliferation rate of osteoblasts was taken as the pharmacodynamic index, and determined by MTT method to draw effect-time curve. In comparison between the effect-time curve and the concentration-time curve, the blood concentrations of geniposidic acid and psoralen were close to the peak when the cell proliferation rate reached its peak, indicating a good correlation between them. The peak blood concentration of isopsoralen was slightly lagging behind the peak of efficacy. According to the correlation analysis after fitting the effect-time curve and the concentration-time curve, salt-processed Qing'e wan had a better correlation than the raw one. The above experimental results showed that the effect-time curve and the concentration-time curve of geniposidic acid and psoralen had a good correlation, and the correlation of salt-processed Qing'e wan was better than the raw one.
