An analytical method was developed for determining amount of natamycin in wine using a C18 minicartridge column and high-performance liquid chromatography (HPLC) with photodiode array (PDA) detection. Natamycin purified from wine was identified in accordance with the retention time and UV spectrum obtained from PDA detection. The limit of quantification of natamycin in wine was estimated as 0.05 microg/ml. Recovery of natamycin in wine was acceptable at 91.0% with low relative standard deviation (2.3%).
