Simultaneous characterization of multiple Psoraleae Fructus bioactive compounds in rat plasma by ultra-high-performance liquid chromatography coupled with triple quadrupole mass spectrometry for application in sex-related differences in pharmacokinetics.
A method for the simultaneous quantification of 13 bioactive compounds (psoralen, isopsoralen, isobavachin, bakuchalcone, neobabaisoflavone, bavachin, corylin, psoralidin, isobavachalcone, bavachinin, corylifol A, bavachalcone, and bakuchiol) by ultra-high-performance liquid chromatography coupled with triple quadrupole mass spectrometry has been developed and validated in rat plasma. Osthol was used as an internal standard and plasma samples were pretreated with one-step liquid-liquid extraction. These analytes were separated using a gradient mobile phase system of water and acetonitrile at a flow rate of 0.2 mL/min on a reverse-phase C18 column and analyzed in the selected multiple reactions monitoring mode. All calibration curves were linear (r > 0.9952) over the tested ranges. The intra- and interday accuracy and precisions of these analytes at three different concentration levels were within the acceptable limits of <15% at all concentrations. The mean recoveries of these analytes at three concentrations were more than 60.2% and the matrix effects were in the range of 85-115%. Stability studies proved that the analytes were stable under the tested conditions. The developed method was applied to evaluating the pharmacokinetic study of 13 bioactive compounds after oral administration of Psoraleae Fructus in rat of different genders. Some active compounds in Psoraleae Fructus had sex-related pharmacokinetics.

Phenolic compounds isolated from Psoralea corylifolia inhibit IL-6-induced STAT3 activation.
Inhibiting interleukin-6 (IL-6) has been postulated as an effective therapy in the pathogenesis of several inflammatory diseases. In this study, seven flavonoids were isolated from the methanol extracts of Psoralea corylifolia by bioactivity-guided fractionation. The structures of bakuchiol (1), bavachinin (2), neobavaisoflavone (3), corylifol A (4), corylin (5), isobavachalcon (6), and bavachin (7) were determined by spectroscopic analysis (1H-, 13C- NMR and MS). We demonstrated that compounds 1-7 showed an inhibitory effect on IL-6-induced STAT3 promoter activity in Hep3B cells with IC50 values of 4.57 ± 0.45, 3.02 ± 0.53, 2.77 ± 0.02, 0.81 ± 0.15, 1.37 ± 0.45, 2.45 ± 0.13, and 4.89 ± 0.05 µΜ, respectively. These compounds also inhibited STAT3 phosphorylation induced by IL-6 in Hep3B cells. Overall, several flavonoids from P. corylifolia might be useful remedies for treating inflammatory diseases by inhibiting IL-6-induced STAT3 activation and phosphorylation.
