Abstract:

In terms of average membrane permeation flux, membrane retention rate and permeation rate of chlorogenic acid, the applications of three microfiltration membranes (MF1, MF2 and MF3), four ultrafiltration membranes (UF1, UF2, UF3 and UF4) and two reverse osmosis membranes (RO1 and RO2) for the purification of the chlorogenic acid-rich extract from Lonicera japonica Thunb were evaluated. MF1, UF1 and RO2 were found to be even better than other similar membranes. Optimal purification was achieved by the sequential combined use of MF1, UF1 and RO2, and the maximum chlorogenic acid recovery was up to 67.75%, and a product with a purity exceeding 13.21% was obtained. Additionally, diafiltration could improve the treatment effect, and the retention rate of chlorogenic acid was decreased from 9.54% to 1.17% in MF1 separation and from 32.36% to 20.11% in UF2 separation after intermittent diafiltration.
