| titleOfInvention | Process for extracting and purifying total organic acid of aralia cordata |
| abstract | The invention discloses a process for extracting and purifying the total organic acid of aralia cordata, which belongs to the technical field of pharmacy, and solves the technical problems of low extraction rate and low purity of the total organic acid of the aralia cordata. The process sequentially comprises the following steps: performing reflux extraction through ethyl alcohol; adding NaCl for salting-out; adding a low-valence/polarity organic solvent for extraction; adding KOH for alkaline treatment; adding concentrated hydrochloric acid for acid deposition; adding NaCl for salting-out; adding the low-valence organic solvent for extraction; performing concentration and drying under reduced pressure to obtain an extract of the total organic acid of the aralia cordata. An optimum aralia cordata organic acid extraction and purification scheme is adopted, so that the total organic acid in the edible aralia cordata can be extracted to the greatest extent, the usage rate of medicinal materials is increased, and the cost is saved; an extraction requirement does not need to be specifically required, and the extraction and purification process is stable, and easy to operate and the total organic acid is suitable for large-scale industrial production. |
