Embodiment 1
[0020] The HPLC analysis and content determination method of embodiment 1 psoralen and isopsoralen
[0021] Chromatographic conditions Chromatographic column Agilent Zorbax SB-C18 column (4.6mm × 250mm, 5 μ m); Adopt gradient elution, mobile phase A phase is 0.1% glacial acetic acid aqueous solution, mobile phase B phase is the acetonitrile solution containing 0.1% glacial acetic acid; Gradient The elution procedure is as follows: at 0 minutes, the mobile phase is 95% A, 5% B; at 20 minutes, the mobile phase is 70% A, 30% B; at 25 minutes, the mobile phase is 50% A , 50% B; at 30 minutes, the mobile phase was 5% A, 95% B. Solution flow rate 1.0mL·min -1 ; The detection wavelength is 246nm; the column temperature is 30°C, and the content of psoralen and isopsoralen can be determined. see figure 1 , 1 in the figure is isopsoralen, and 2 is psoralen.
Embodiment 2
[0023] Take 1 kg of psoraleae, dry at 50°C for 6 hours, add 8 times the amount of water, heat and reflux for 2 hours in a slightly boiling state, extract the extract, filter it, concentrate under reduced pressure, and precipitate with alcohol, adjust the alcohol concentration to 80%, take the supernatant, and concentrate Add ethyl acetate to extract after reaching no alcohol, separate the water layer, apply macroporous resin, wash with water, discard, and continue to elute with 30% ethanol aqueous solution. The eluate was collected, concentrated under reduced pressure until alcohol-free, and freeze-dried to obtain total psoralen glycosides. As determined by the method of Example 1, the content of psoralen in the total psoralen was 38%, and the content of isopsoralen was 42%.
Embodiment 3
[0025] Take 1 kg of psoraleae, dry at 50°C for 6 hours, add 8 times the amount of water and heat to reflux for 2 hours, then filter the extract, concentrate under reduced pressure, and precipitate with alcohol, adjust the alcohol concentration to 70%, take the supernatant, and concentrate Add ethyl acetate to extract after reaching no alcohol, separate the water layer, apply macroporous resin, wash with water, discard, and continue to elute with 50% ethanol aqueous solution. The eluate was collected, concentrated under reduced pressure until alcohol-free, and freeze-dried to obtain total psoralen glycosides. Measured according to the method of Example 1, the content of psoralen in the total psoralen is 40%, and the content of isopsoralen is 42%.
