文摘In this paper, active components of velvet antler polypeptide were extracted and separated. The molecular weight and purity of velvet antler polypeptide were determined by MALDI-TOFMS. The different influence factors such as matrix, sample concentration and laser energy were studied. This method is convenient and suitable for the identification of congener biochemical samples.
