Abstract

The invention discloses a preparation method for cough-relieving loquat syrup.The preparation method comprises the steps that S1, loquat leaves, radix platycodonis, ephedra herb, radix stemonae, licorice roots and semen plantaginis are taken, mixed to be uniform and then put in a container, water is added for decocting, filtrate is filtered out, filter residues are left in the container, and first filter liquid is obtained; S2, semen armeniacae amarum is put in the container, water continues to be added for decocting, filtrate is filtered out, and second filter liquid is obtained; S3, menthol and green tea extract are dissolved in ethyl alcohol, the mixture is mixed and stirred to be uniform, and a mixed solution is obtained; S4, saccharose is boiled to obtain simple syrup, and after the simple syrup is cooled to normal temperature, the simple syrup, the first filter liquid in the S1, the second filter liquid in the S2 and the mixed solution in the S3 are mixed to be uniform to obtain the product.According to the preparation method for the cough-relieving loquat syrup, semen armeniacae amarum is added in the second time of decocting, and therefore semen armeniacae amarum can be prevented from affecting achieving of the effect of the monarch drug loquat leaves; moreover, the green tea extract can improve the stability of the cough-relieving loquat syrup, and therefore the guarantee period is prolonged.
