| titleOfInvention | Method for separating and purifying ajoene in garlic extract by molecular distillation |
| abstract | The invention belongs to the technical field of separation and purification of effective components of traditional Chinese medicines, and discloses a method for separating and purifying ajoene in a garlic extract by molecular distillation. The method utilizes an ultrasonic technology to rapidly extract the ajoene from the garlic, and then utilizes a molecular distillation separation and purification technology to separate and purify the ajoene to obtain a high-purity ajoene product. The I-grade distillation in the adopted molecular distillation device is used for removing residual solvent, moisture and impurities with low boiling point in the garlic extract, and the II-grade distillation is used for separating and purifying ajoene in the I-grade fraction, so that an ajoene product with the purity of more than 88 percent is obtained. The prepared product has no solvent residue, high purity and light color. The method has the advantages of simple and convenient operation, low preparation cost, good separation effect, high product purity, high utilization rate of the raw material dregs and the like, and is suitable for industrial production. |
