To establish a MPLC method for the content determination of resveratrol in Polygonum cuspidatum Sieb. Et. Zucc, Analytical column SOURCE 5RPC ST 4.6/150 was used with a mixture of acetonitrile+water (30+70,volume ratio ) as mobile phase ,with a flow rate of 1ml/min and the UV detection wavelength was 306nm, The linear range was 0.6-1.6mg/ml (r=0.9919). The average recovery of prodatin was 103.0%-90.4%(RSD=7.21%). The method is convenient and accurate. Result indicated a reverse phase chromatography media based o n polystyrene/divinyl benzene has excellent resolution for resveratrol in cuspidatum. P rovide theoretical support for process development.

色谱条件采用SOURCE 5RPC ST 4.6/150预装柱，以乙腈/水(体积比30/70)溶液为流动相，流速1ml/min、检测波长为308nm，结果表明，白藜芦醇在0.6～1.6mg/ml的浓度范围内峰面积积分值与浓度的相关系数r=0.9919；所测定的虎杖饮片中白藜芦醇平均含量为0.304％，平均回收率为103.0％～90.4％；实验表明，以聚苯乙烯为基架的反相介质对于虎杖中自藜芦醇具有良好的分辨率，适合其有效成分的检测、分离，对虎杖中白藜芦醇制备的科学研究过渡到工艺开拓有很好的借鉴。

A 4.70 g partially pure ginsenoside Rd was obtained together,the yield of which was 15.6%.We adopt the mothod of crystallization to epurate.

结果表明，在硅胶柱分离中，从30 g二醇类皂苷分离得到含人参皂苷Rd的皂苷9.46 g，得率为32.5%，得到较纯人参皂苷Rd4.70 g，得率为15.6%。

An EPMA was performed quantitatively on the influence of Ce upon the Mn segregation in cellcrystals, columnar and Equiaxial dendrites of high-Mn steel.

Gingerols in ginger oleoresin were separated by AB8 macroporous adsorption resin and silica gel column chromatography. The samples were characterized by the gas chromatography-mass spectrometry method.The peak area normalization method was used to determine the relative percentage of the components and the rate of accumulation of gingerol was determined by contrasting with gingerol standard samples. The results showed that gingerols was concentrated on the 3rd and the 4th parts.

采用硅胶柱层析和AB8大孔树脂吸脱附两种方法分离姜油树脂中的姜酚，采用气相色谱-质谱(gas chromatography-mass spectrometry， GC-MS)对分离样品进行表征，用峰面积归一化法对测试样品的气相色谱-质谱结果进行分析，确定了分离样品中各组分的相对峰面积百分比。
