Results: The hairy root was successfully induced and the hairy root culture system was set up; The opines assay was positive for mannopine and agropine; The result of determination showed that there were a lot of anthroquinone constituents in the rhubarb hairy root and the contents of rhein, aloe-emodin, emodin or 8-O-methylchrysophanol were respectively higher than those in wild plant root.

结果：诱导出了天山大黄发根，并建立了发根离体培养系；从发根中检测到甘露碱、农杆碱的存在；定量分析发现，天山大黄发根中含有多种蒽醌类成分，其中大黄酸、芦荟大黄素、大黄素、大黄酚-8-甲醚的含量分别高于原植物根中的含量。

Methods: The medicinal plant Rheum wittrochii Lundstr., was genetically with Ri plasmid harbouring in Agrobacterium rhizogenes 9402 strain to induce hairy roots; transformed the opines from the hairy roots were assayed by paper electrophoresis; the contents of free anthroquinones such as aloe-emodin, rhein, chrysophanol, emodin, physcion, 8-O-methylchrysophanol from the hairy roots were quantitatively determined by HPLC technique.

用发根农杆菌Agrobacterium rhizogenes 9402 所含Ri质粒遗传转化药用植物天山大黄以诱导发根用纸电泳法检测发根中冠瘿碱的存在；用高效液相色谱法测定发根中芦荟大黄素、大黄酸、大黄酚、大黄素、大黄素甲醚、大黄酚-8-甲醚等游离蒽醌化合物的含量。

Among these results,expression patterns of 21 genes were consistent with those in the microarray data.3.3 Emodin potentiates growth inhibition induced by gemeitabine in pancreatic cancer cells in vitroTo investigate the effect of ernodinon cell viability,pancreatic cancer cell lines (Pane-1,Mia Paca-2 and Bxpc-3) were treated with increasing concentrations of emodin (0-160μM) for 24,48 and 72 hours.

结果显示21个基因两种方法所得基因表达倍数大致相当。3.3 Emodin在体外增加吉西他滨对胰腺癌细胞生长的抑制为了探讨Emodin对胰腺癌细胞生长的影响，应用MTT方法检测不同浓度的Emodin(0-160μM)作用于胰腺癌细胞24h、48h和72h的效应。

The emodin did not inhibited multiplication of TMV in infected leaf discs or infectivity of TMV-RNA in vitro. The infectivity of TMV recovered by dialysis from incubations with emodin in vitro has regained showed that the emodin did not direct viricidal effect. The emodin did not reduce infectivity of TMV when applied before TMV inoculation.

大黄素对粒体无形态破坏作用，与TMV混合后经过透析可恢复大部分的侵染活性，体外混合不影响TMV-RNA的侵染活性，并无体内抑制复制作用，预先接种也不影响TMV随后的侵染。
