Extraction and Purification of 3,4-Two Vanillyl Tetrahydrofuran in Nettle |
| |
| Abstract: | Objective] The aim was to extract and purify 3,4-two vanillyl tetrahydrofuran in nettle, to lay a good basis for further research on the function mechanism. Method] Using alcohol aqueous solution for reflux extraction, the method and conditions for adsorption and sepa-ration of 3,4-two vanillyl tetrahydrofuran in nettle with macroporous adsorption resin were studied, ultrafiltration membrane purification tech-nology was adopted for purification. Result] X-5 macroporous adsorption resin had better adsorption ability to 3,4-two vanillyl tetrahydro-furan;when ethanol concentration was 60%, the desorption effect was best, after the purification of the ultrafiltration membrane, purity of 3, 4-two vanillyl tetrahydrofuran in nettle could up to 85. 3%. Conclusion] Using X-5 macroporous resin and ultrafiltration membrane purifi-cation technology can effectively extract 3,4- two vanillyl tetrahydrofuran in nettle, the study provides basis for research of 3,4- two vanillyl tetrahydrofuran in nettle. |
