Study on extraction method of chlorogenic acid from Honeysuckle.

Objective To study the water extraction method of chlorogenic acid in Honeysuckle.Methods Orthogonal experiment design was used.Three factors were studied as indexes that might affect the yield rate of chlorogenic acid,including water quantity,extraction temperature and time required.Results The best extraction condition was:10 times amount of water,1 hour of extraction at 75 ℃.Conclusion This extraction method is convenient and feasible,and can improve the extraction of chlorogenic acid from honeysuckle.
