以HepG2.2.15细胞为乙肝病毒(HBV)感染的体外实验模型,采用MTT法测定实验组细胞的活力,采用酶联免疫吸附试验(ELISA)测定实验组HepG2.2.15细胞上清液中乙肝病毒表面抗原(HBsAg)、e抗原(HBeAg)的含量,采用实时荧光定量PCR法检测HepG2.2.15细胞上清液HBV DNA水平,研究金银花蕾乙醇提取物(LA)、乙酸乙酯部位(LE)及活性成分3-咖啡酰奎宁酸体外抗乙肝病毒的作用。研究结果显示:LA、LE及3-咖啡酰奎宁酸对HepG2.2.15细胞的生长增殖均无显著抑制作用;LA和LE作用8 d可抑制HBeAg分泌;100 μg/mL 3-咖啡酰奎宁酸对HepG2.2.15细胞上清液中HBsAg、HBeAg分泌及DNA复制均具有显著的抑制作用。上述结果表明,金银花中的活性成分3-咖啡酰奎宁酸具有显著的抗HBV活性。
HepG2.2.15 cells were used as a model for hepatitis B virus (HBV) infection ,in vitro., MTT assays were used to determine the viabilities of HepG2.2.15 cells in different experimental groups. In order to study the effects of ethanol extracts and 3-caffeoylquinic acid from ,Lonicera japonica, flower buds against HBV ,in vitro, enzyme-linked immunesorbent assays (ELISA) were applied to quantify the contents of HBsAg and HBeAg in the supernatant of each experimental group, and real-time PCR was applied to quantify the HBV DNA levels. The results indicate that the ethanol extract (LA), ethyl acetate fraction (LE) and 3-caffeoylquinic acid have no inhibitory effects on the viabilities of HepG2.2.15 cells; LA and LE can inhibit the secretion of HBeAg after 8-day treatment; 3-caffeoylquinic acid can inhibit the secretion of HBsAg, HBeAg and the replication of HBV DNA in HepG2.2.15 cells at the concentration of 100 μg/mL. In summary, the active ingredient 3-caffeoylquinic acid exerts prominent activity against HBV ,in vitro,.
