ABSTRACT
OBJECTIVE:
To extract and purify organic acids with macroporous resins from Folium Isatidis.METHODS:
Folium Isatidis was extracted with 70% aqueous ethanol(pH=2)by Soxhlet extraction.The process was optimized by employing orthogonal test design with the content of anthranilic acid as the index.RESULTS:
The resin HPD100 had much better adsorption capacity and desorption ratio by using 3 BV 60% aqueous ethanol to extract organic acids in Folium Isatidis than other resins.The results showed that HPD100 possessed the better ecomic under the concentration of sample 0.18mg?mL-1,the condition of pH 3.5,and flowing rate of 2BV?h-1.CONCLUSION:
Macroporous resin HPD100 may be value of isolating and purifying the organic acids from Folium Isatidis.
