Effect of Basic and Acidic Additives on the Separation of Some Basic Drug Enantiomers on Polysaccharide-Based Chiral Columns With Acetonitrile as Mobile Phase
The separation of enantiomers of 16 basicdrugs was studied using polysaccharide‐based chiral selectors and acetonitrile as mobilephase with emphasis on the role of basic and acidicadditives on the separation and elution order of enantiomers. Out of the studied chiral selectors, amylose phenylcarbamate‐based ones more often showed a chiral recognition ability compared to cellulose phenylcarbamate

enantioselective analysis using immobilized amylose tris‐(3‐chlorophenylcarbamate) as chiral stationaryphase in conventional high‐performance liquid chromatography (HPLC) with Chiralpak ID (4.6 mm ID × 250 mm, 5 µm silica gel) and micro‐HPLC with Chiralpak ID‐3 (0.30 mm ID × 150 mm, 3 µm silica gel) was conducted. Pharmaceutical racemates of 12 pharmacological classes, namely, α‐ and β‐blockers, anti‐inflammatory
在传统的高效液相色谱(HPLC)中采用Chiralpak ID(4.6 mm ID×250 mm,5 µm硅胶)和Micro-HPLC(Chiralpak),使用固定化直链淀粉三(3-氯苯基氨基甲酸酯)作为手性固定相进行比较对映选择性分析进行ID-3(0.30 mm ID×150 mm,3 µm硅胶)。筛选了12种药理学级别的药物外消旋体,即α和β阻滞剂,抗炎药,抗真菌药,多巴胺拮抗剂,去甲肾上腺素-多巴胺再摄取抑制剂,儿茶酚胺,镇静催眠药,利尿药,抗组胺药,抗癌药和抗心律失常药在正常相位条件下。研究了有机改性剂对分析物保留和对映体识别的影响。对1-ac烯醇,卡洛芬,西脂洛尔,西唑烷醇,咪康唑,戊唑醇,4-羟基-3-甲氧基扁桃酸,1-吲哚醇,1-(2-氯苯基)乙醇,1-苯基-2-丙醇,黄烷酮,6-羟基黄酮,4-溴戊二酰亚胺和戊巴比妥使用常规HPLC,用5 µm硅胶柱填充4.6 mm内径。尽管如此,在装有3
