An extraction method of a
salvia extract and a
safflower extract and a preparation method of a
salvia-safflower oral preparation relate to an extraction method of
salvia and safflower, and a preparation method of a salvia-safflower preparation. The extraction of the
salvia extract comprises the following steps: first, refluxing; second, acidification; third, adsorption. The extraction of the
safflower extract comprises the following steps: first, decoction; second, acidification; third, adsorption. The preparation of the salvia-safflower oral preparation comprises the following steps: mixing the
salvia extract and the
safflower extract, adding auxiliary materials to prepare an oral
dosage form. According to the invention, the salvia and the safflower are extracted separately; the effective components are extracted fully and completely, which effectively improves the inherent quality of the product, improves and guarantees the
controllability of intermediates and the finished product; the control indexes of effective components in the salvia-safflower oral preparation of the invention are very scientific and reasonable; the invention increases the purity of effective components, reduces impurities, reduces risks for clinical application of injections; the preparation process of the invention has simple operations, high efficiency, low cost, and is applicable to industrial production.
