摘要:

为研究山茱萸中抗过敏活性成分,采用透明质酸酶抑制实验对山茱萸中活性组分进行初步筛选;采用细胞脱颗粒抑制实验对透明质酸酶抑制活性较高的组分进一步评估;采用气相色谱-质谱联用法(GC-MS)进行成分分析。结果表明山茱萸石油醚部位(petroleum ether extract of Corni Fructus,COPE)具有显著透明质酸酶抑制活性,其IC50值为3.11 mg/mL;经硅胶柱层析分离得到4个透明质酸酶抑制活性更高的组分,其中组分COPE-8对RBL-2H3细胞脱颗粒抑制作用更显著,呈剂量依赖形式且具低细胞毒性。经20 μg/mL COPE-8处理后,RBL-2H3细胞脱颗粒释放的组胺和β-氨基己糖苷酶分别减少46%和39%;经GC-MS分析,COPE-8中主要活性物质为萜类物质,包括α-香树脂醇、β-香树脂醇和香紫苏醇。结果表明COPE-8具有显著的抗过敏活性,在抗过敏活性物开发方面具有一定的应用价值。

Abstract:

In the present study,the potential anti-allergic constituents in Corni Fructus were investigated. The anti-allergic components of Corni Fructus were preliminarily screened by hyaluronidase inhibition assay. The fractions with high hyaluronidase inhibition activity were further evaluated by the degranulation inhibition test of RBL-2H3 cells in vitro. The anti-allergic components were analyzed by gas chromatography-mass spectrometry (GC-MS). The results showed that the petroleum ether extract of Corni Fructus (COPE) had a significantly anti-hyaluronidase activity with an IC50 value of 3.11 mg/mL. Four fractions with higher anti-hyaluronidase activity were separated by silica gel column chromatography,among which COPE-8 had a more significant inhibitory effect on RBL-2H3 cell degranulation in a dose-dependent manner and showed low cytotoxicity. After treatment with 20 μg/mL COPE-8,the histamine and β-hexosaminidase released from RBL-2H3 cells were reduced by 46% and 39%,respectively. The main active components in COPE-8 were α-amyrin,β-amyrin,and sclareol,by GC-MS analysis. These findings signpost that COPE-8 has remarkable anti-allergic activity and has potential application in the development of anti-allergic active substances.
