Abstract: Lipid transfer protein (LTP, Pru p 3) is the major allergen protein of peach (Prunus persica L. Batsch). In this study, Pru p 3 was purified from the peel and pulp of honey peach, nectarine, flat peach, and yellow-fleshed peach using a microchromatographic column, ZipTipC18, and identified by liquid chromatography-tandem mass spectrometry (LC-MS/MS). The results showed that Pru p 3 with a purity of 95% was obtained and confirmed. The purification method can provide technical support for further studies of peach Pru p 3.

Key words: peach; allergens; lipid transfer protein; purification; mass spectrometry
