| titleOfInvention | Method for preparing high-purity ailanthone |
| abstract | The invention discloses a method for preparing high-purity ailanthone. The method comprises the steps of taking ailanthus seed crude powder, adding 5-10fold of 50-80% methanol solution to ultrasonically extract for 2-3 times; adding extract solution to macroporous resin to absorb after concentrating; eluting by 5-10 fold column volume of 50-70% methanol solution; adding eluent to a polyamide resin column to absorb after concentrating, eluting by the methanol solution, concentrating the eluent and then separating by a high speed countercurrent chromatograph; carrying out online monitoring by an ultraviolet detector, and collecting fraction to dry under reduced pressure. The ailanthone prepared by the method is simple to operate and small in pollution; the purity of the obtained product is greater than 95%; and industrialized production is easily achieved. |
