| Abstract: | Complete separation of chlorogenic acid(1) and isochlorogenic acid(2) from the honeysuckle flower was achieved by the self-made spiral tube fractional extraction device.The separation was performed with water as the mobile phase and ethyl acetate as the stationary phase.Feed liquid 20 ml,mobile phase 50 ml and stationary phase 40 ml were pumped into the device in every cycle.Under these conditions,the purity of 1 and 2 was 64.1%and 82.3%,with recoveries of 85%and 90%. |
