The invention relates to a honeysuckle high purity chlorogenic acid distilling technology. The technology includes four steps: adding NaHSO3, yield promoting agent and clarifier, sheet frame filter-press, passing macro hole adsorbing resin to gain concentrated solution, spraying and drying to gain taking orally chlorogenic acid; adding alcohol and depositing, adding water taking second clarifying process, taking active carbon process, pressure decreasing and concentrating, spraying and drying to gain honeysuckle distilling material; adding beta-CD into the clarified solution to take complex reaction, adding cyclohexanone decomplexing to gain concentrated chlorogenic acid, drying in vacuum could gain the chlorogenic acid that the content could be 90%; dissolving the concentrated solution by alcohol, using silica gel chromatography column to take section analysis, testing, combining the same section, decreasing pressure and drying, crystallizing, the chlorogenic acid that has the content over 95% would be gained, which was tested by HPLC method.
