Abstract

The invention belongs to the field of natural organic chemistry, and relates to a method for enriching and purifying folic acid in herba orostachyos by utilizing macroporous adsorption resin. The method is characterized in that a macroporous adsorption technology is used for separating and purifying folic acid, the adsorption selectivity on folic acid is good, adsorption and desorption are fast, and the adsorption capacity is large; extraction is convenient and fast, raw material sources are rich, production cost is low, separation effect is obvious, extraction purity is high, a folic acid semi-finished product with the content of more than 35% and a folic acid final product with the content of more than 98% can be obtained, and the defects of relatively low conventional extraction rate and low extraction purity are overcome. Macroporous adsorption resin with stable physicochemical properties, large surface area, high exchange speed, high mechanical strength, strong anti-pollution ability and good thermal stability is selected, folic acid can be selectively adsorbed from a solution through physical adsorption, adsorption is fast, desorption is fast, and adsorption capacity is large.
