A simple and highly sensitive spectrofluorimetry has been investigated for determination of menadiol acetate based on its self-fluorescence and the interaction of cetyltrimethylammonium bromide with menadiol acetate. The maximum excitation wavelength appears at 279 nm with fluorescence occurring at 339 nm. At the dimension of menadiol acetate 0 - 1 mg/L, the value of the fluorescence intensity appears good linear relations with the contents of menadiol acetate. The relative coefficient r is 0. 9998 and the RSD is 1. 14% respectively. 醋酸甲萘氢醌 β-环糊精 溴化十六烷基三甲铵 荧光光度法 药物分析 menadiol acetate β-cyclodextrin cetyltrimethylammonium bromide spectrofluorimetry pharmaceutical analysis O657.39 国家自然科学基金（203160234）;教育部分析化学名牌课程项目资助 2002-02-01 2021-04-01 2
