实验步骤: 50 mg of micronised fenoterol HBr was dispersed uniformly in a solution of soy-bean lecithin (600 mg) 95% pure in 2 g of Arcton 11. The Arcton 11 was allowed to flash off, leaving behind a dispersion of fenoterol particles in lipid. To this dispersion, 5 g of micronised lactose was added. The resultant powder composition was tumbled in a ball-mill to ensure uniform mixing.

实验步骤: A sample of 75 mg of fenoterol HBr was dissolved in 1.5 mL of 95/5/0.05 CH3CN/isopropanol/HNEt2 and applied in 100 μL injections to a CHIRALPAK® AD-H 10×250 mm 5 μm semi-preparative column using a waters 2690 Separations Module, PDA set to 280 nm. The eluting solvent was 95/5/0.05 CH3CN/isopropanol/HNEt2, 5 mL/min. Retention times for (S,S) and (R,R) isomers were 4.8 min and 7.8 min, respectively.
