Abstract

Abstract:

Biological characteristics and contents of secondary metabolites (chlorogenic acid，total flavonoids) of 10 clones of Eucommia ulmoideswere investigated. The clone with purple leaves has purple blade with green midrib on the adaxial side，green blade on the abaxial side and graceful crown. The clone of clump leaves is endowed with tightly dense crown with unique shape. Therefore，both of the clones are good materials suitable for being used as ornamental tree. Additionally，the clone with purple leaves possessed high contents of chlorogenic acid and flavonoids，which made it also proper to herbal medicine use. We propose that the clone should be set as a model and spread in the main production area of E. ulmoides and garden scenic area because of its medicinal and ornamental value.

Key words: Eucommia ulmoides, distinguished variety, character, secondary metabolites, chlorogenic acid, flavonoids
