对金乌香冲剂中槟榔碱进行了酸性染料比色法定量方法研究,结果表明在pH=5.0时,槟榔碱可与溴甲酚绿生成稳定呈色离子对,在槟榔碱浓度范围1.65μg/mL~10.4μg/mL内线性关系良好,r=0.9992,平均回收率99.7%,RSD=2.1%(n=5)。

[Abstract]
An acid dye colorimetry was developed for the quantitative determination of arecoline in’‘ Jinwuxiangchongji". Arecoline forms a stable color ionpair with bromocresol green in a HAc-NaAc buffer of pHS. 0. The absorption is proportional to the concentration of arecoline in the range of 1. 65 pg/mL-10. 4 p.g/mL (r=0.9992) and average recovery 99.7% (RSD=2.1%,n=5).
