To reveal the natural active component variation rule in barks of Eucommia ulmoides Oliv., which provided basal reference for the plus tree screening and effective utilization of the medical woody plants, the active components in barks of different Eucommia ulmodies variance-types were detected by RP-HPLC. The results showed that the content and allocation of the five active components in barks was evidently different among four variance-types. Comparing to the deep-vertical splitting and the chap variance-types, four natural contents including geniposidic acid, geniposide, pinoresinol diglycoside, chlorogenic acid and total amount of the five constitutes were detected to be relatively higher in barks of the smooth and the shallow-vertical splitting types. Community of the smooth type could be given priority to breeding selection for cultivating excellent Eucommia ulmoides medicinal variety.
