[Study on technology of extracting geniposidic acid from Eucommia ulmiodes and its application].
OBJECTIVE
To study the optimum technology of extracting bioactive component named geniposidic acid in Eucommia Ulmiodes by orthogonal test.


METHODS
An orthogonal test table L16(4(5)) was used with the factors of extracting time, temperature, times, ethanol consistency and the ratio of solid to liquid. The content of geniposideic acid was determined by RP-HPLC.


RESULTS
The optimum technology was: temperature 50 degrees C, time 1 h, once, consistency 80%, and the ratio of solid and liquid 1:12. Under the condition, the best material of Eucommia Ulmiodes for extracting geniposidic acid was chosen.


CONCLUSIONS
The technology can provide some theoretic advice for industry.
