Objective To improve the quality standard of Minuo Hair Solution and to ensure product quality. Methods Thin layer chromatography (TLC) and UV-visible spectroscopy (UV-Vis) method was used for the qualitative identification of Angelica sinensis, Paeoniae Radix Rubra, Dictamni Cortex and minoxidil respectively. The Quantitive determination of minoxidil was completed by first order derivative spectroscopy. Results The spots in TLC were clear without inference. And the same color spots appeared in the corresponding position of references and reference drugs. The UV-Vis spectral absorption of minoxidil were in (230±3), (262±3),(286±3) nm. The linear range of minoxidil was obtained between 6.2 and 18.6 μg/ml (r=0.9997). The average recovery was 99.4% (RSD=0.22%). Conclusion The method is simple,accurate and reproducible,and can be effectively used to control the quality of Minuo Hair Solution.
