This method was applied to simultaneously determine the active ingredients in one Chinese compound hypotensor named Zhen Ju Jiang Ya Pian, in which the contents of clonidine hydrochloride, hydrochlorothiazide and rutin is very different as 0.03mg : 5mg : 20mg per tablet, and satisfactory results were obtained by adjusting their sensitivity by selecting the suitable diluting agent.

复方降压药珍菊降压片中活性成分盐酸可乐定、氢氯噻嗪和芦丁的含量分别为每片0.03mg∶5mg∶20摘要mg，由于盐酸可乐定的含量比氢氯唾嗦和芦丁低很多，因此要实现三种待测样品的同时测定比较困难，而我们通过选择合适的稀释溶剂调节三种待测样品的电流响应，实现了这三种待测样品的同时分离，测定结果令人满意。

Bleaching of rutin was also observedunder 380～490nm, which indicated the destroying of the colorific system of rutinduring its reaction with peroxyl radicals.

在380～490nm观察到了芦丁的褪色反应，这表明在芦丁与有机过氧自由基反应的过程中其发色体系受到了破坏。

The calibration curve was linear in the range of 0.003 40～0.02432 mg.ml-1 for rutin. The sample was stable within 8 hours and the recovery rate of rutin was 98.56 %. And in precision test, RSD=1.38%. ConclusionThere is rutin in SFE extract of Sparganium stoloniferum.

结果在三棱的超临界萃取物中含有芦丁成分，建立的液相色谱方法在芦丁浓度为0.003 40～0.02432 mg.ml-1的范围内线性关系良好，样品在8 h内稳定，平均加样回收率为98.56%，以峰面积作精密度实验，RSD为1.38%。

The rutin content in hypocotyls reached the highest level when IAA (0.5 μg/mL) and rutin (40 μg/mL) were added to the medium.

当培养基中含有40 μg/mL的芦丁和0.5μg/mL的IAA时，胚轴中累积的芦丁达到高峰。

Part II. Synthesis, characterization and fluorescent properties of rare earthcomplexes of rutin Rare earth complexes of rutin have been synthesized by the reaction of rare earth chloride with rutin in alcohol solution (pH=7～8). The composition and thermal stability of the complexes were characterized by elemental analysis, molar conductivity, thermal analysis, IR, UV.
