摘要

Suspension cultures of Eucommia ulmoides Oliv. were developed and shown to accumulate chlorogenic acid. MS medium plus 2.0 mg l(-1) 2,4-dichlorophenoxy acetic acid was used for the cell suspension cultures of Eucommia ulmoides. The chlorogenic acid content of suspension cells was analyzed by capillary electrophoresis, and the mean content was 2.15%, approximate to that of Eucommia ulmoides leaves.
