Objective: To explore the optimal extraction process by a blitzkrieg extractor and the adsorption separation by macro-porous resin for chlorogenic acid in Lonicera macranthoides. Methods: The transfer rate of chlorogenic acid was used as the main as-sessment index, the response surface test was adopted to optimize the main influencing factors in the extraction process by a blitzkrieg extractor for chlorogenic acid in Lonicera macranthoides. The transfer rate and the product purity of chlorogenic acid were used as the main assessment indices, the water extract solution of Lonicera macranthoides was used as the raw material, single factor test was adopt-ed to optimize the main influencing factors in the adsorption separation process by a macroporous resin for chlorogenic acid in Lonicera macranthoides. Results: The optimum conditions of the extraction process by a blitzkrieg extractor and the adsorption separation by a macroporous resin for chlorogenic acid in Lonicera macranthoides were as follows: the solid-liquid ratio was 1 : 23, the extraction time was 4. 7 min, the rotating speed was 6 000 r·min-1, the type of macroporous resin was ADS-7, the amount ratio of medicinal materi-als to macroporous resin was 1: 5, the flow rate of sample solution was 1 BV·h-1, the macroporous resin column was eluted by 1 BV water at the speed of 1 BV·h-1followed by 6 BV 20% ethanol solution at the speed of 2 BV·h-1, and the eluent of 20% ethanol so-lution was collected. The average transfer rate of chlorogenic acid was 90. 12% (RSD=1. 33% ) with the purity of 50. 30% (RSD=2. 19% ). Conclusion: A new route of the extraction process by a blitzkrieg extractor and the adsorption separation by a macroporous resin for chlorogenic acid in Lonicera macranthoides has established through the optimization and verification experiments. The process with high transfer rate of chlorogenic acid (the purity of chlorogenic acid product was over 50% ) is fast, and the solvent is healthy and easy to recycle.
