| 1 | Analysis of Low-polar Ginsenosides in Steamed Panax Ginseng at High-temperature by HPLC-ESI-MS/MS显示文摘A high performance liquid chromatography coupled with electrospray ionization-tandem mass spectrome try(HPLC-ESI-MS/MS) method was developed for the analysis and identification of ginsenosides in the extracts of raw Panax ginseng(RPG) and steamed Panax ginseng at high temperatures(SPGHT). A total of 25 ginsenosides were extracted include of which 10 low-polar ginsenosides, such as ginsenosides F4, Rk3, Rh4, 20S-Rg3, 20R-Rg3 and so on, were identified according to their HPLC retention time and MS/MS data. The results indicated that the low polar ginsenosides were seldom found in RPG. For the exploration of the transformation pattern of the ginsenosides in steam processing, the standards of ginsenosides Re, Rg1, Rb1, Rc, Rb2, Rb3 and Rd were selected and hydrolyzed at a temperature of 120 oC. The results show that these polar ginsenosides can be converted to low-polar ginsenosides such as Rg2, Rg6, F4, Rk3 and Rg5 by hydrolyzing the sugar chains. | ZHANG Yu-chi1,2, PI Zi-feng1, LIU Chun-ming2, SONG Feng-rui1, LIU Zhi-qiang1 and LIU Shu-ying1 1.

| 3 | 新型PET泡沫AIREX~ T92的性能特点试验研究显示文摘在当前复合材料夹层结构用泡沫芯材领域中,PVC泡沫由于其良好的综合力学性能占据着主导地位,PET泡沫的应用则由于其脆性而受到一定的限制,加铝(Alcan)复合材料集团芯材事业部在其AIREX(T91基础上研制的新型PET泡沫AIREX(T92成功突破了这个弱点。本文对AIREX(T92泡沫的静、动态力学性能,高温下的力学性能以及高温下的尺寸稳定性进行了试验研究。结果表明,AIREX(T92作为一款综合性能优异的结构泡沫芯材,可以用于风能、游艇和轨道交通等各个领域。 | 姚辉 Moritz Pieper Lars Massüger Roman Gtzi 李岩 | 2009 | 材料工程2009，37，S2： | 6 |
| 4 | The Cosmic Dust in Suzhou Granite:Ablated Products of a Cometary Explosion | Hu Zhong-wei,Wang Er-kang,Wan Yu-qiuDepartement of Astronomy,Nanjing University,Nanjing 210093,China Department of Earth Sdence,Nanjing University,Nanjing 210093,China Cosmic dust has been collected in large number from deap-sea sediments,Greenland ice deposits,the stratosphere and space,of cosmic dust,some are the unmelted micrometeorite,and most are the ablated products of me-teoroids in the atmosphere.Cosmic dusts were recovered from two sites of the 1908 Tunguska explosion and the 1965 Revelstoks explosion Since 1987,a large number of microspherules have been extracted from Suzhou granite of China Their suface and section structures,mineral and chemical composition show that these microspherules are of the ablated cosmic dust.The microspherules occurred in the inner contact complex intrusion.It suggests that the microspherules may be products of the same event and were aggergated in some strata and then captured by the emplacement of granitic magma.Although the microspherules are similare to other ablated cosmic dusts,there are some diferences.Our calculated results of cometary motion through the atmosphere and explosion show that the microspherules may be the ablated dust of a comet with mass above 1015g at its explosion near the ground. | 1996 | 紫金山天文台台刊1996，15，3： | 2 |
| 5 | Structural Characterization of Anhydroicaritin Glycosides Using ESI-FT-ICR Mass Spectrometry显示文摘Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR-MS) was used to determine the structures of anhydroicaritin glycosides by the MS/MS experiments of anhydroicaritin glycosides and their methylated derivatives. With high accuracy FT-ICR-MS provides much information about the structures of compounds, FT-ICR-MS shows the great potential application in the structural characterization of unknown compounds. | Shao Xiang XIONG*, Dan PU, Bin XIN, Guang Hui WANG Beijing Mass Spectrometry Center, Center for Molecular Science, Chinese Academy of Sciences, Beijing 100080 | 2002 | Chinese Chemical Letters2002，13，11： | 2 |
