硫酸沙丁胺醇（SA）可选择性作用于β2肾上腺素受体，为支气管舒张剂。本文推荐用四氯配（CH）和二氯素醌（DI）作为－电子受体试剂在醛存在或不存在下与SA形成电子转移复合物，因而显色。利用此种比色法测定片剂中的SA，耗费少，且省时。1仪器Perkin－ElmerModel550S双光束紫 Salbutamol sulfate (SA) selectively acts on the β2-adrenergic receptor as a bronchodilator. This article recommends the use of tetrachloro (CH) and dichloroquinone (DI) as an electron-acceptor reagent to form an electron transfer complex with SA in the presence or absence of aldehydes and thus develop color. Using this colorimetric method to determine SA in tablets, it takes less time and is less time consuming. 1 instrument Perkin-ElmerModel550S double beam violet
