3 observing the effect of the drug before and after processing
The Kunming mouse is half male and female, and water is not forbidden for 12 h. Placed in a 250mL beaker. A cotton ball is placed in a watch glass with the diameter smaller than that of the beaker, a screen is covered on the cotton ball, 0.3mL of ammonia water is injected into the cotton ball, and the beaker is quickly inverted so that the ammonia water stimulates the mouse to cause cough. The strong contraction of the abdominal muscles of animals is taken as the standard, and the mouth opening and the exhalation are performed simultaneously. 100 mice qualified for initial screening of induced cough are judged to be 100 within 1min if the cough frequency is more than or equal to 3, and are randomly divided into 10 groups, 10 mice/group and half of males and females. Group 1 is physiological saline group, positive drug group (codeine 6 mg. kg)-1) High and low dose group (0.5 g.20 g) of radix Stemonae crude drug-1,0.25g·20g-1) The high and low dose group (0.5 g.20 g) of radix Stemonae honey-fried product (the method of the invention)-1,0.25g·20g-1) High and low dose (0.5 g.20 g) for radix Stemonae honey-fried (only cane molasses is added)-1,0.25g·20g-1) High and low dose (0.5g 20 g) group of radix Stemonae honey-fried (traditional method) products-1,0.25g·20g-1) 10 groups of mice were fasted for 8h before administration, water was prohibited for 2h, and the mice were continuously administered for 3d, and tested 1h after the last administration. Mice were stimulated with ammonia to elicit coughing as per the above method. The latency of each group of mice and the number of coughs in the mice within 3min were observed and recorded. The results are shown in Table 2.
TABLE 2 cough incubation period and cough frequency of mice in each experimental group
Figure GDA0003316706390000061
Figure GDA0003316706390000062
Note: compared with the blank control group, P is less than 0.05, P is less than 0.01, and P is less than 0.05 when compared with honey-fried products, honey-fried products (only cane molasses) and honey-fried products (the method of the invention) in the same dosage.
The effect of each experimental group on cough latency and cough frequency in mice is shown in table 2. The experimental results show that compared with the blank group, each experimental group can prolong the cough incubation period of the mice and reduce the cough frequency. The honey-fried products (the method of the invention) and the honey-fried products (only cane molasses is added) have significant differences from the honey-fried products (the traditional method), which shows that the cough relieving effect of the radix stemonae tuberose after processing is enhanced, and the cough relieving effect of the radix stemonae tuberose is further improved by adding the molasses fermentation liquor and the cane molasses.
Investigation of the second and third honey-roasting processes
1. Single factor test
1.1 concentration selection of molasses fermentation broth
In the test, the concentrations of 1%, 3%, 5%, 8% and 10% cane molasses fermentation liquor are compared, and after being moistened for 2h at normal temperature, honey water and stemona root medicinal materials are added into the honey water in a ratio of 1:1:2, wherein the honey water comprises honey, cane molasses and purified water, and the mixture is processed at 120 ℃ for 20min, and the stemonine content is taken as a research index. As a result, 3%, 5% and 8% of molasses fermentation liquor have higher tuberostemonine content, so 3-8% of molasses fermentation liquor is selected.
1.2 selection of smoldering time
In the test, 5% cane molasses fermentation liquor is respectively moistened for 1 hour, 1.5 hours, 2 hours, 2.5 hours, 3 hours, 3.5 hours, 4 hours, 4.5 hours and 5 hours, honey, cane molasses and purified water are added into honey water according to the proportion of 1:1:2 and the stemona root medicinal material is added into the honey water, the mixture is processed for 20min at the temperature of 120 ℃, and the moistening effect of the medicinal material and the content of the stemonine in the stemona leaves are taken as investigation indexes. As a result, the moistening effect is better when the moistening is carried out for 2-4 h, and the content of the tuberostemonine is higher, so the moistening time is selected to be 2-4 h.
1.3 selection of the amount of sugar cane molasses added
The cane molasses is black in color, sticky and contains a large amount of microorganisms, and the proportion of the microorganisms to the honey affects the quality of the molasses and the appearance and the internal quality of the radix stemonae. In the test, after 5% of cane molasses fermentation liquor is moistened for 2 hours, the weight ratio of honey to cane molasses to water is compared to 1:1:1, 1:2:2 and 1:3:3, and the appearance quality and the sessileine content of the mixed honey juice are considered indexes. The honey, the cane molasses and the water are in a weight ratio of 1:1:1 to 1:2:2, the appearance quality of the honey juice is good, the sessileine content is high, and therefore the weight ratio of the honey to the cane molasses to the water is 1: 1-2.
1.4 selection of processing temperature
In the test, 5% of cane molasses fermentation liquor is moistened for 2h, then honey, cane molasses and purified water are added into honey water in a ratio of 1:1:2 and radix stemonae in a ratio of 1:1, and the honey water is processed for 20min at 100 ℃, 110 ℃, 120 ℃, 130 ℃ and 140 ℃, and the appearance and the stemonine content of the processed sample are used as indexes for investigation. As a result, the sample processed at 110-130 ℃ has better appearance and character and higher content of the tuberostemonine, so the processing temperature is selected to be 110-130 ℃.
1.5 selection of processing time
In the test, 5% of cane molasses fermentation liquor is used for moistening for 2 hours, then honey water and radix stemonae medicinal materials are added into the honey water according to the proportion of 1:1:2, and the mixture is processed at 120 ℃ for different times: 5min, 10min, 15min, 20min, 25min, 30min, and taking appearance and character of the processed sample and tuberostemonine content as examination indexes. As a result, the appearance of the processed sample is better after being processed for 10-20 min, and the content of the tuberostemonine is higher, so the processing temperature is selected to be 10-20 min.
2. Determination of optimum process for roasting with honey
By using L9(34) The orthogonal test method is used for researching the concentration of molasses fermentation liquor, the moistening time, the processing temperature and the processing time by a 4-factor 3 level, and the result is as follows:

TABLE 5 variance analysis of radix Stemonae processed with honey
Figure GDA0003316706390000091
The comprehensive scoring result analysis shows that the factor sequence influencing the honey roasting effect is A & gt C & gt D & gt B, and the preferred horizontal combination result is A2B1C2D3. From the anova results, factor A, C, D had a significant effect (P)<0.05), factor B had no significant effect (P)>0.05). Because the factor B has no obvious influence on the processing effect, the energy conservation is considered, the production efficiency is improved, the large-scale production is convenient, the factor B can be changed into the lowest level, namely, the soaking is carried out for 1 hour, and finally, the optimal processing technology of the honey-fried radix stemonae is preferably selected as A through comprehensive analysis2B1C2D3The method comprises mixing 0.2-0.3 mm thick radix Stemonae with 5% molasses fermentation solution, moistening at room temperature for 2 hr, adding Mel solution, and processing at 120 deg.C for 20 min.
