The 1H NMR fingerprint of Eucommia ulmoides acquired with a CPMG pulse sequence was analyzed with the complete reduction to amplitude-frequency table (CRAFT) approach. The signals of target compounds were extracted without chemical separation and purification. Quantitative analysis showed that the average concentration of pinoresinol glucoside (PDG) in Eucommia ulmoides got from Guiyang medical plant garden was 0.275 6% with a relative standard deviation (RSD) of 1.69%. The results were consistent with those obtained by high performance liquid chromatography (average content of 0.269 6% and RSD of 0.65%). NMR fingerprint and multivariate statistical analysis also revealed that there existed significant differences between Hunan and Guizhou Eucommia ulmoides Oliver.
