Eucommia ulmoides oliv Extract
Eucommia ulmoides Oliv is a Eucommia plant of Eucommiaceae, which contains high chlorogenic acid. Chlorogenic acid, also known as 3-car-feoyquinic acid, is a phenylpropanoid synthesized by the intermediate product of pentose phosphate pathway (HMS) in the process of aerobic respiration (Gao Jinming et al., 1999). Recent research results show that the content of chlorogenic acid in Eucommia ulmoides leaves is high, up to 1 ~ 5.5 (Zang Youwei, 1989). Chlorogenic acid has many pharmacological effects such as cholagogic, antibacterial, antiviral, antihypertensive, increasing leukocyte and exciting central nervous system (Zhang anling et al., 2OO1). It is an important raw material for health products, food, drugs, cosmetics and other industries. Therefore, the production of chlorogenic acid from Eucommia ulmoides leaves has great social and economic benefits
