[0052] Experimental Example 1: Research on the components of psoraleae that cause hepatotoxic damage
[0053] In the previous study, coumarin glycosides (psoralen, isopsoralen), coumarin (psoralen, isopsoralen, psoralen), flavonoids (psoralen), and flavonoids (psoralen) were isolated from psoralen. Compounds such as bone lip isoflavone, isopsoralen chalcone, psoralen dihydroflavone, corylifol A, neopsoralen isoflavone), monoterpene phenol (bakuchiol), etc.
[0054] Estrogen-like activity studies on the above-mentioned related compounds [1] , the results showed that: psoralen and isopsoralen exert estrogen-like effects by activating ERα; Compounds such as phenol exert estrogen-like effects by activating ERα and ERβ. The binding rate of psoralen and isopsoralen to ERα is much higher than that of ERβ, while bakuchiol mainly acts on ERβ.
[0055] research shows [2]-[3] Long-term use of estrogen in large quantities can cause animal liver damage, such as hepatomegaly, liver ce...

[0061] Experimental Example 2 Study on liver toxicity of different medicinal parts of psoraleae medicinal material after water extraction
[0062] In order to clarify the medicinal parts of psoraleae that caused liver toxicity after water extraction, further studies were carried out on the psoralen raw drug group (psoralen medicinal material), psoralen water extract group, and psoralen dregs group after water extraction. liver toxicity studies.
[0063] Preparation of psoralen water extract and psoralen dregs: add 8 times the amount of psoralen medicinal material to heat reflux extraction at 100°C, extract twice, each time for 1.5 hours, filter to obtain the water extract, and concentrate under reduced pressure It becomes a thick paste, which is the water extract; the dried dregs obtained after filtration are the dregs of psoraleae after water extraction.
[0064] Determination of psoralen, isopsoralen, psoralen, isopsoralen, The content of psoralen B and bakuchiol (assay ...

[0071] Experimental Example 3 Hepatotoxicity and drug efficacy research of the processed product obtained by the processing method of the present invention
[0072] 3.1. Liver toxicity study:
[0073] Rat hepatotoxicity studies were carried out with psoraleae original drug and processed products obtained by the processing method of the present invention. For the processing method of the present invention, refer to the preparation of psoralen dregs in Experimental Example 2. The results are shown in Table 2-4.
