The ethyl acetate-soluble fraction of the methanolic extract from the seeds of Psoralea corylifolia was found to inhibit the release of beta-hexosaminidase, as a marker of antigen-IgE-induced degranulation in RBL-2H3 cells. Sixteen constituents were isolated from the ethyl acetate-soluble fraction and several constituents, Delta(1),3-hydroxybakuchiol (IC(50) = 49 microM), Delta(3),2-hydroxybakuchiol (69 microM, bavachin (58 microM), and psoralidin (ca. 100 microM), showed inhibitory activities against the antigen-induced degranulation.
补骨脂种子甲醇提取物的乙酸乙酯可溶部分被发现能抑制β-己糖胺酶的释放,β-己糖胺酶是RBL-2H3细胞中抗原-IgE诱导脱颗粒的标志物。从乙酸乙酯可溶部分分离出16种成分,其中几种成分,Δ(1),3-羟基补骨脂酚(IC50 = 49微摩尔)、Δ(3),2-羟基补骨脂酚(69微摩尔)、补骨脂素(58微摩尔)和补骨脂定(约100微摩尔),对抗原诱导的脱颗粒表现出抑制活性。
