    Estrogenic activities of Psoralea corylifolia L. seed extracts and main constituents.[Pubmed: 21382704]

    Estrogenic activities of ethanol extract and its active components from Psoralea corylifolia L. were studied using various in vitro assays. The main components from ethanol extract were analyzed to be bakuchiol, psoralen, isobavachalcone, Isobavachromene, and bavachinin. In a fractionation procedure, hexane and chloroform fractions showed estrogenic activity in yeast transactivation assay and E-screen assay. In yeast transactivation assay, ethanol extract, hexane, and chloroform fractions showed significantly higher activities at a concentration of 1.0 ng/ml, and bakuchiol at the concentration of 10(-6) M was showed the highest activity, especially, which was higher than genistein at the same concentration.
    In E-screen assay, cell proliferation of bakuchiol (10(-6) M) showed similar estrogenic activity with genistein (10(-6) M). In ER binding assay, bakuchiol displayed the strongest ER-binding affinity (IC(50) for ERα=1.01×10(-6) M, IC(50) for ERβ=1.20×10(-6) M) and bakuchiol showed five times higher affinity for ERα than for ERβ.

    In vitro BACE-1 inhibitory phenolic components from the seeds of Psoralea corylifolia.[Pubmed: 18666047]

    A new isoflavone, neocorylin ( 1) was isolated from the seeds extract of Psoralea corylifolia L. (Fabaceae), together with eight known constituents ( 2 - 9), i. e., bakuchiol ( 2), psoralen ( 3), bavachromene ( 4), Isobavachromene ( 5), bavachalcone ( 6), isobavachalcone ( 7), 7,8-dihydro-8-(4-hydrophenyl)-2,2-dimethyl-2 H,6 H-[1,2- B:5,4- B']dipyran-6-one ( 8), and bavachinin ( 9). The structure of the new isoflavone 1 was elucidated as 7-hydroxy-3-[2-methyl-2-(4-methylpenten-3-yl)-2 H-chromen-6-yl]-4 H-chromen-4-one by spectroscopic analyses.
    Neocorylin ( 1) as well as related compounds 2, 4 - 6, 8 and 9 exhibited a significant inhibitory effect on baculovirus-expressed BACE-1 in vitro.
