Methods: The cyclodextrin, concentration, pH, organic solvent were studied, and the results indicated that the enantiomer of ephedrin and ephedrine levorotatory were baseline separated under the following experimental conditions: uncoated fused silica capillary (75 μm× 68 cm), 25 mmol/L Tris, 2% HP-β-CD and 1% SBE-β-CD, pH was adjusted at 3.0 by phosphoric acid, and 15 kV separation voltage.

以SBE-β-CD和HP-β-CD二元环糊精为手性添加剂，探讨了环糊精种类及浓度、pH、有机溶剂种类等因素对麻黄碱及伪麻黄碱对映体拆分的影响，结果表明：毛细管：未涂渍熔融石英毛细管75μm×68 cm（有效长度60 cm）。分离用缓冲液为25 mmol/L的Tris缓冲液，含2.0% HP-β-CD和1.0% SBE-β-CD，用磷酸调节pH至3.0。

The product contains glutamic acid, hamamelis extract, levorotatory VC and dipotassium glycyrrhizinate, and can activate cells, prevent and relieve sensitive skin, moisturize and whiten skin and make skin white, tender, moist and shining.

活化肌肤细胞，预防和舒缓肌肤敏感症状，滋润和美白肌肤，用后令肌肤净白细致，滋润亮泽。

The induced supramolecular chirality was found to be dependent on the absolute configuration of lateral residues, that is, the polymers with-configurational oxazolinyl chromophores tended to form chiral aggregates with levorotatory handedness, while polymers obtained from the-monomer offered dextrogyrate one upon the addition of Cu salt. A model, in which side groups would arrange in a helix fashion, is employed for describing the unusual chirality.

由此提出了侧基在Zn／Cu协同配位作用下形成螺旋状排列的模型，即侧基螺旋模型。N-噁唑啉苯基马来酰亚胺与甲基丙烯酸甲酯共聚得到了耐热性能好(热分解温度大于296℃)的光学活性聚合物~(25D=-7.8°(来源：Af4BC论文网www.abclunwen.com)～-36.6°。
