The wall-breaking extraction method of the reference literature in the preparation of the rhodiola rosea extract comprises the steps of firstly moistening the medicinal materials by using a vacuum medicine moistening machine, then carrying out microwave wall-breaking in a microwave dryer, and then putting the medicinal materials into an extraction tank for extraction. The vacuum herbal medicine infiltrating machine has the working principle that air in gaps of medicinal material fibers is pumped out by vacuum, water rapidly enters plant cell tissues through capillaries under the negative pressure condition, and the purpose of infiltrating is to make dehydrated plant cells absorb water and swell, so that conditions are created for subsequent processes. The principle of using microwave drying equipment to break the cell wall is that the dried material absorbs microwave energy in a microwave drying equipment field and is converted into heat, moisture is evaporated through the heat, and the cell wall is broken in the process of discharging the moisture from inside to outside, so that the purposes of drying the material and breaking the cell wall are achieved. The microwave drying equipment comprises: tunnel type microwave drying equipment, box type microwave drying equipment and vacuum type microwave drying equipment. When the polar medium is not added with an electric field, the dipoles of the polar medium do disorder movement, and the whole body is electrically neutral; when an external electric field is applied, the dipoles in the medium are rearranged in a directional manner, namely, one end with positive electricity tends to the negative electrode, and the other end with negative electricity tends to the positive electrode, so that the dipoles which move disorderly and are not regularly arranged become polarized molecules with certain orientation and regular arrangement, and meanwhile, the external electric field gives potential energy to the dipoles. The stronger the polarization of the medium, the more energy the medium stores, and if the direction of the electric field is changed, the direction of the dipole arrangement is changed. During the transformation, due to the thermal movement of the molecules, the interaction between adjacent molecules and the pole-changing effect of the polar molecules, a friction-like effect is generated, so that the polar molecules acquire energy and are expressed in the form of thermal energy, and the temperature of the medium is increased. During microwave drying, microwave energy is transmitted into the material and absorbed by water, the microwave energy is instantaneously converted into heat energy to simultaneously heat the inside and the outside of the material, so that the pressure of water vapor in the inner layer is suddenly increased, the water vapor is driven to be discharged to the surface layer to cause cell wall rupture, the inner layer of the material firstly appears a drying layer and gradually expands towards the outer layer, and the drying sequence from inside to outside is completely different from that of the conventional drying process.

As described above, it is apparent from the results of examples 1 to 8 that the recovery rate of salidroside in the extract can be significantly improved by adding both glacial acetic acid and calcium chloride to the water used for drug wetting in the vacuum drug wetting step of the method of the present invention, and the recovery rate of salidroside is low when neither glacial acetic acid nor calcium chloride is added or only either is added. In experimental example 1, when the extracts of examples 1 to 8 and the commercially available rhodiola rosea oral liquid were used as reagents for biological activity examination, although the dosages of the administered drugs were the same in terms of salidroside, the biological activity of the extracts of examples 1 to 5 was significantly better than that of other extracts, which is a surprising and complete finding that, although the dosages of the administered drugs were the same in terms of salidroside, other substances that may produce biological activity were present in the extracts obtained by different methods, i.e., the mass spectra of the active substances were different, and thus the biological activity was different. These results also show that by using the method of the present invention to prepare the rhodiola extract, the concentration of salidroside in the extract is higher, and the biological activity of the active substance spectrum is stronger, therefore, when the rhodiola extract obtained by the present invention is used to prepare the pharmaceutical composition, the dosage of the rhodiola medicinal material can be reduced, but the biological activity is not weakened; or the obtained composition can show more excellent biological activity under the condition of keeping the feeding amount in the existing product preparation process.
