RESULTS The solubility, photostability and release rate of CPT were increased in PEG 350-3.0 PAMAM solution in comparison with that in G 3.0 PAMAM solution.

结果 PEG350-3.0PAMAM较之同代PAMAM对喜树碱具有更强的增溶作用和更快的释药速度，同时可改善喜树碱的光敏性，增加其稳定性。

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。

We postulate that this is a Lewis base activating Lewis acid reaction.
