Acuta, Semen Galli Sonatii Praeparatum, Glycyrrhiza Glabra in stainless steel decoction pot, add 25℃ purified water, make the liquid level higher than the medicinal material 5 cm, add water immediately after covering, soak for 30 min (make water molecules penetrate into medicinal material cells, promote cell swelling, effective components are more easily dissolved, facilitate subsequent decoction extraction), then drain and reserve. Elaeagnus angustifolia L. is only washed and drained for standby. Select monosaccharide syrup and potassium sorbate as auxiliary materials, wherein monosaccharide syrup has the function of correcting the taste, can cover up the bitter and astringent taste of medicinal materials themselves, make the oral liquid taste better, and monosaccharide syrup can also increase the consistency of oral liquid, make the hanging wall time of oral liquid on the bottle wall reach ≥15 s standard, improve the appearance quality and overall quality of oral liquid; potassium sorbate as a preservative can inhibit the growth and reproduction of microorganisms, prolong the shelf life of oral liquid.

[0016] Table 1 Medicinal material ratio 2, medicinal material decoction and filtration 2.1, medicinal material decoction Put the soaked Flos Farfugii, Flos Chrysanthemi, Pericarpium Citri Reticulatae, Rhizoma Pinelliae Praeparatum, Tuckahoe, Semen Armeniacae Amarum, Ginger Magnolia Officinalis, Ephedra Herb, Peucedanum Graveolens, Fritillaria Thunbergii Miq, Flos Syzygii, Compound Honey Lily, Perilla Frutescens L. var. Acuta, Semen Galli Sonatii Praeparatum, Glycyrrhiza Glabra in stainless steel decoction pot, add 25℃ purified water to 2000 ml, then start decoction, boil the medicinal liquid in the stainless steel decoction pot to boiling, then quickly turn to medium or small fire to continue to decoct, decocting time is 20 min. When the color of medicinal liquid changes to dark brown, turn to small fire, open the pot cover to warm up, add Elaeagnus angustifolia L., the warm-up time is controlled in 5 min (Elaeagnus angustifolia L. contains volatile and heat-sensitive components, long-time decoction will cause the loss of these components, affect the efficacy and quality of oral liquid). During the whole decoction process, use wooden stirring tool to stir uniformly, ensure that the medicinal material is heated uniformly and the effective components are fully dissolved.

[0017] 2.2, medicinal liquid filtration After decoction is completed, turn off the fire, let the medicinal liquid naturally air to 25℃ normal temperature, then use glass funnel, enamel funnel and qualitative filter paper (pore size is 6 μm) to filter the medicinal liquid, improve the clarity of medicinal liquid, get pure medicinal liquid.

[0018] 3, medicinal liquid concentration and alcohol precipitation 3.1, medicinal liquid concentration The filtered pure medicinal liquid is transferred to a clean medicinal material decocting pot for boiling and concentration. When the temperature of the medicinal liquid rises to 95°C, the concentration phase begins, and the temperature of the concentrated liquid is closely monitored while using wooden stirring tools for uniform stirring. When the medicinal liquid becomes completely thick, the fire is turned off for cooling. When the temperature cools to 60°C, the state of the medicinal liquid is observed, which is in a viscous state and free of impurities (concentrated to 6.8% of the original volume), the concentration operation is stopped, and the concentrated medicinal liquid is obtained.

[0019] 3.2, Measurement of volume The concentrated medicinal liquid is carefully poured into a 500 ml measuring cylinder, the measuring cylinder is inclined at 45° during pouring, and it is slowly poured along the wall of the measuring cylinder. After pouring is completed, the measuring cylinder is left to stand for 15 min, and after the bubbles in the medicinal liquid completely disappear, the scale line of the measuring cylinder is read horizontally, and the volume of the medicinal liquid is read and recorded.

[0020] 3.3, Alcohol precipitation of medicinal liquid The volume of ethanol to be added is calculated according to the following formula: C1 x V1 = C2 (V1 + V2); In the formula, C1 is the concentration of ethanol (95%), V1 is the volume of ethanol to be added, C2 is the target final concentration of ethanol (50%), and V2 is the volume of concentrated medicinal liquid.

[0021] The calculated volume ratio of concentrated medicinal liquid to 95% ethanol is 1:1.11.

[0022] According to the calculated amount, 95% ethanol is slowly added to the concentrated medicinal liquid while stirring, and the stirring time is ≥15 min (to ensure that the ethanol and concentrated medicinal liquid are fully mixed, the impurities are uniformly dispersed in the ethanol solution, and the precipitation reaction is promoted), and the temperature of the medicinal liquid is maintained at 60°C during stirring. After the concentrated medicinal liquid and ethanol are fully mixed, a plastic wrap is added to the container opening for sealing (to prevent ethanol evaporation and external impurities from entering), and it is placed in a 4°C refrigerated environment for 24 h (in a low temperature environment, the solubility of impurities decreases, and they are more likely to precipitate, thereby achieving the purpose of removing impurities).

[0023] 4, De-alcoholization and refining of medicinal liquid 4.1, Ethanol recovery The concentrated medicinal liquid-ethanol mixture after alcohol precipitation is filtered through a filtration device to separate the precipitated impurities, and then the filtrate is transferred to a decocting device for heating and boiling to 95°C. After the fire is turned off, the medicinal liquid is cooled to ≤60°C, and the smell change is closely observed. If there is still ethanol remaining, the above operation is repeated, and the heating is continued until there is no ethanol smell in the decocting liquid, indicating that the ethanol has been completely recovered.

[0024] 4.2, Refining of medicinal liquid The medicine liquid after recovery of ethanol is divided into portions, each portion weighing 85 g. After the division, purified water is added to each portion to dilute to 125 ml, and proper stirring is performed to mix the medicine liquid uniformly. 38 g of monosaccharide syrup is added to the diluted medicine liquid, and 5 ml of 100 mg / ml potassium sorbate solution (0.5 g of potassium sorbate is dissolved in 5 ml of water at 40°C or below) is added quickly while stirring to ensure that the medicine liquid is below 40°C. After the addition of the auxiliary materials, purified water is added to the medicine liquid to 250 ml while stirring to complete the volume determination, and the sauviea flower oral liquid is obtained.

[0025] 5. Measurement of pH and density of sauviea flower oral liquid Two batches of sauviea flower oral liquid are prepared, and the pH and density of the two batches are measured.

[0026] 5.1. Measurement of pH pH test paper is used for the measurement. A piece of pH test paper is placed on a glass container, and a dropper is used to extract an appropriate amount of sauviea flower oral liquid to be detected and drop it in the middle of the pH test paper. After 3 s, a color comparison card is used to compare the color with the test paper, and the pH value is read and recorded after the pH test paper is stable.

[0027] 5.2. Measurement of density of medicine liquid The medicine liquid obtained from the two experiments is respectively placed in a clean and clean specific gravity bottle, and the mass of the specific gravity bottle is measured in advance. The volume of the medicine liquid is obtained according to the scale line on the specific gravity bottle. After the mass of the two bottles of medicine liquid is weighed, the mass of the specific gravity bottle is subtracted, and the final density of the medicine liquid is obtained by dividing the net mass of the medicine liquid by the volume of the net medicine liquid.

[0028] II. Test results Two batches of sauviea flower oral liquid are prepared, and the pH and density of the two batches are measured. The results are shown in Tables 2 and 3.

[0029] Table 2 pH values of two batches of sauviea flower oral liquid Table 3 densities of two batches of sauviea flower oral liquid The results show that the pH value of the sauviea flower oral liquid prepared by the present application is between 4.4 and 6.5, and the density is between 1.13 g / cm 3 and 1.20 g / cm 3The sand date flower oral liquid meets the quality standard, the whole sand date flower oral liquid is brownish-brown, sweet in taste, sweet and slightly bitter in taste, and has potential effects of clearing lung, resolving phlegm and relieving cough. The above results show that the sand date flower oral liquid preparation method provided by the application can prepare the sand date flower oral liquid with stable performance, can be used as a sand date flower processing method suitable for large-scale and industrial production, and provides a new scheme for sand date flower deep processing research and development and sand date flower industrial production.
