AI Technical Summary

Problems solved by technology

But this product still has the following deficiencies: (1), during the storage process, with the prolongation of the storage time, the pH value of the liquid medicine gradually decreases, which can cause changes in the color and clarity of the liquid medicine and affect the quality of the medicine, especially the sterilization of the liquid medicine Afterwards, the PH value dropped more, sometimes by more than 1.0

(2) Scutellaria baicalensis extract contains baicalin, baicalein and other ingredients, among which baicalein has anti-inflammatory, anti-allergic, antibacterial, choleretic, diuretic, and anti-cholesterol effects, and is widely used in infectious hepatitis and nephritis , pyelonephritis and other diseases, but because baicalein is almost insoluble in water and does not contain carboxyl groups, it is insoluble in alkaline water, so it is difficult to dissolve and is filtered out as impurities, which affects the efficacy of medicines

At the same time, the solubility of baicalin in carboxyl-containing dilute alkali increases, but its stability is not good. At the same time, during storage, it can precipitate out of the solution with the change of the pH value of the solution, or hydrolyze to form baicalein, which is almost insoluble in water and produces precipitation, which affects the clarification of the drug. Spend

(3), chlorogenic acid is caffeic acid quinate, so it can be hydrolyzed by both acid and alkali, so the pH value of the drug solution is required to be high, and the pH of the drug solution is easily hydrolyzed after changing, which affects the efficacy of the drug. curative effect
