香莢醛是一种法定菊物,在英国药典(1953年版)没有测定方法,虽1948年的英国药典附录上有测定方法,但不满意,因终点不很明显,后来—些作者也报告过用改进的二硝基苯肼法及新的容量法(在硷性液中以过氧化氢定量氧化香莢醛法)赤不满意。 Fragrance is a statutory substance, and there is no method of determination in the British Pharmacopoeia (1953). Although the method of determination was applied to the appendix of the British Pharmacopoeia of 1948, it is unsatisfactory because the end point was not very clear and some authors later reported Not satisfied with the improved dinitrophenylhydrazine method and the new volumetric method (quantitative determination of the flavonoid with hydrogen peroxide in alkaline solution).
