The Study of Purifying Coumarin Chemical Compounds in “Yubaizhi” Angelica Dahurica by Macro-Porous Absorption Resin

Abstract:

The method of using macro-porous absorption resin to rurify coumarins in “Yubaizhi” angelica dahurica was used in this study. A kind of better resin was chosen from D-101 resin and HPD600 resin by the comparison of adsorption rate, desorption rate and purity. The result showed that D-101 resin was better for purifying coumrins. Then these conditions of purifying were discussed. when the sample concentration was 0.1g medicinal materials per milliliter and the adsorbent speed was 1ml/min, the effect of adsorption was better. And per gram resin could adsorb coumarins of 3g sample material. When the eluotropic speed of 80% ethanol was 1ml/min and the dosage of eluent reaches was 7 multiple of bed volume, the effect of elution was better. The result of demonstration test showed the effect of purifying coumarin was better with above-mentioned conditions.
