[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. METHOD: 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. RESULT: 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. CONCLUSION: The technology can provide some theoretic advice for industry.

[Study on optimizing the analysis condition for active compound in Eucommia olive].

The absorption spectroscopic determination of aucubin by condensation with p-dimethylaminobenzaldehyde was optimized in this paper. A high sensitive method was established and the linearity range of the method was from 4.5 to 45 microg x mL(-1). The influences of the factors, such as the dosage of coloring agent, reaction time, heating temperature and the dose of acid etc., on the system were studied. And the result indicated that all of the factors had obvious effects on the system. The method has been applied to determining the content of aucubin in the extract of Eucommia olive with satisfactory results.
