Results The calibration curve for scutellarin was linear in the concentration range of 0.126 5～0.632 5μgml1 (r=0.999 6, n=5).The average recovery was 97.28% with RSD=1.81%.

结果黄芩苷的含量在0.126 5～0.632 5 μgml1 (r=0.999 6，n=5)范围内线性关系良好，平均回收率为97.28%，RSD为1.81%。

野黄芩苷和丹酚酸B的平均回收率分别为99.7%和100.3%，RSD(n=9)分别为0.9%和0.5%。

观测了灯盏花植株的生长发育进程，全草及各部位的干物质积累规律和全草主要有效成分灯盏乙素和咖啡酸酯含量的积累规律。

Results were shown as followings:(1) Sodium selenite at 0～2.5 μmol/L significantly increased the antioxidative capacity of L-02 cells without having remarkable impact on SMMC-7721 cells;(2) Sodium selenite at concentrations above significantly increased telomerase activity, hTERT gene expression and telomere length of L-02 cells without significant impact on SMMC-7721 cells;(3) Sodium selenite at higher concentrations (larger than 5 μmol/L) resulted in peroxidation of L-02 cells, while scutellarin significantly counteracted its effect;(4) Selenium-rich amino acids from silkworm pupas in the range of 0.5～2.5 μmol/L Se significantly inhibited SMMC-7721 cell growth, induced apoptosis and cell cycle change, and the generation of reactive oxygen species. In contrast, sodium selenite and selenomethionine only had weak impact on them at the same concentrations;(5) A new selenium-containing protein was found from selenium-rich silkworm pupas, which is worthy to be study further;(6) An expression vector containing ansense RNA of hTERT gene were constructed and used to transfect SMMC-7721 cells. They were observed to inhibit hepatoma cells.

结果如下：（1）0～2.5μmol/L亚硒酸钠显著性增强L-02细胞的抗氧化能力；而对SMMC-7721细胞的作用不显著；（2）该浓度硒显著性提高L-02细胞端粒酶活性、增强hTERT基因表达和延长细胞端粒长度；而对SMMC-7721细胞的作用均不显著；（3）高浓度硒（5μmol/L以上）显著性抑制L-02细胞生长、致细胞过氧化，灯盏花素能拮抗硒所致过氧化、降低硒毒性；（4）0.5～2.5μmol/L富硒蚕蛹氨基酸显著性抑制肝癌细胞SMMC-7721生长、导致细胞凋亡和周期改变、诱导细胞产生活性氧，同浓度亚硒酸钠和硒代蛋氨酸对其抑制不显著；（5）富硒蚕蛹蛋白经分离纯化和鉴定后发现存在一新含硒蛋白，其结构和功能有待研究；（6）通过已有的含hTERT基因质粒，成功构建hTERT反义RNA表达质粒，转染SMMC-7721细胞后对其生长具有抑制作用。
