A novel Eucommia antifungal peptide, named EAFP3, was isolated from the bark of Eucommia ulmoides by NaCl extract, gel filtration and reverse phase high performance liquid chromatography. The molecular mass of EAFP3 is 4157.3 Da, and its partial amino acid sequence is -.LYQQLIAGITLNK.-. EAFP3 exerts an inhibitory activity against Candida albicans in vitro and the drug concentration required for 50% growth inhibition (IC50) is 31.25μg/mL.
