Description

Novel bagged tea for preventing coronavirus pneumonia and preparation method thereof

Technical Field

The invention relates to the technical field of health-care tea bag preparation, in particular to a novel coronavirus pneumonia prevention tea bag and a preparation method thereof.

Background

2019 novel coronavirus (2019-nCoV) was discovered from pneumonia cases in 2019, and named by world health organization in 1 month and 12 days 2020. On 30/3/2020, the WHO announces a New Coronavirus Pneumonia (NCP) epidemic as an emergent public health event of international concern. Millions of people have been infected, about 5 million people die.

Coronaviruses are a large family of viruses known to cause the common cold and more serious diseases such as Middle East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS). The novel coronavirus is a new strain of coronavirus that has not been previously discovered in humans. People of all ages may be infected, mainly adults, of which the elderly and infirm and sick seem to be more susceptible, and children and pregnant women are also susceptible to pneumonia infected by the novel coronavirus. After people are infected with coronavirus, the common signs of the person are respiratory symptoms, fever, cough, shortness of breath, dyspnea and the like. In more severe cases, the infection can lead to pneumonia, severe acute respiratory syndrome, renal failure, and even death.

There is currently no specific treatment for diseases caused by the novel coronavirus. However, many symptoms are treatable and therefore need to be treated according to the clinical condition of the patient. In addition, the adjuvant care of infected persons can be very effective.

The third edition of the national diagnosis and treatment of pneumonia infected by coronavirus (trial implementation) confirms that NCP belongs to the category of epidemic diseases in traditional Chinese medicine, causes the disease to be qi of epidemic crime, is located in the lung, and has the basic pathogenesis characteristics of dampness, heat, toxicity and stasis. The Tong Xiaolin academy states that the epidemic should be distinguished from pestilence and pestilence, and belongs to the category of cold-dampness (pestilence). Pestilence and pestilence belong to yang disease in nature, the final result is yin impairment, and yin impairment is the main line. The disease is a yin disease, the ending is impairment of yang, and the impairment of yang is the main line. In therapeutic treatment, cold and dampness are the main causes. For pathogenic cold, which is suppressed by pathogenic dampness, it is treated by pungent-warm exterior-releasing methods to dispel and expel pathogenic cold. For damp pathogen, it is fragrant and needs to avoid the filth and transform it into turbid. The epidemic situation shows that the symptoms of most patients are obviously improved after Chinese medicine intervention treatment. For example, the traditional Chinese medicine composition can quickly improve the symptoms of patients in the aspect of treating mild symptoms, and has obvious improvement on fever reduction, cough reduction, sore throat, extreme inappetence and hypodynamia of the patients. The traditional Chinese medicine improves severe cough, chest distress, coarse breath and fever of severe patients, reduces the conversion of severe patients to critical diseases, and has higher conversion rate to common patients.

At present, Chinese medicinal preventive formulas are published in a plurality of regions, for example, the Chinese medicinal preventive formula No. 1: 3g of rhizoma atractylodis, 5g of honeysuckle, 3g of dried orange peel, 2g of reed rhizome, 2g of mulberry leaf and 10g of raw astragalus; the traditional Chinese medicine prescription No. 2 comprises: 10g of raw astragalus, 10g of fried bighead atractylodes rhizome, 10g of divaricate saposhnikovia root, 6g of cyrtomium rhizome, 10g of honeysuckle, 10g of fortune eupatorium herb and 6g of tangerine peel; the internal prescription for preventing the novel coronavirus pneumonia comprises the following components: 10g of honeysuckle, 15g of reed rhizome, 15g of cogongrass rhizome, 10g of wrinkled gianthyssop herb, 6g of angelica dahurica and 6g of tsaoko amomum fruit. After the decoction is decocted, the decoction is large in amount, the traditional Chinese medicine is thick in taste, bitter and astringent in mouthfeel, the general acceptance degree is not high, and stomach discomfort is easily caused due to the bitter and astringent mouthfeel, and certain stimulation is generated more or less. It is not suitable for long-term administration in terms of taste and comfort.

The application publication No. CN 108452195A discloses a tea beverage with antiviral cold resistance for sub-healthy people, which consists of rhizoma dioscoreae nipponicae, rhizoma phragmitis, lophatherum gracile, folium mori and liquorice and is suitable for the sub-healthy people in the early stage of influenza A or B.

Evaluation of mouthfeel

The tea bags of examples 1-5 and comparative examples 6-8 were placed in 500ml glass cups, respectively, and brewed with 300ml boiling water for 5min, and tasted when the temperature dropped to 35 ± 5 ℃, and the mouth feel and odor of different tea bags were compared and scored, and the results are shown in table 2.

TABLE 2 taste evaluation results

Grading standard: the content is preferably-4 points, more preferably-3 points, usually-2 points, and still more preferably-1 point.

As can be seen from Table 2, the tea bags of examples 1-5 all had higher taste scores than those of comparative examples 6-8, wherein the proportion of mint in comparative example 6 is too high, so that the cool and refreshing taste of mint is easy to appear, and the stimulation is too strong and not easy to accept; in contrast 7, the ginseng has too few parameters, the fragrance and the taste of the ginseng cannot be reflected, and the overall effect of promoting the secretion of saliva is weakened, so the ginseng has little fragrance and is sweet and weak; in comparative example 8, too little red bean was used, and the sweetness was not sufficiently corrected, and the whole sweetness was weak. The tea bag prepared by the raw material formula of the invention is proved to have better taste and more delicate fragrance, and is a tea bag with good taste and smell.

Water extract determination test

2g of the tea bags obtained in the examples 1-3 and the comparative examples 9-10 are put into a 500ml conical flask, 300ml of boiling water is added, the mixture is immediately transferred into a boiling water bath for leaching for 45min, the hot mixture is filtered under reduced pressure, tea residues are washed for a plurality of times, the filter paper is communicated and transferred into a baking dish, the mixture is dried for 1h at the constant temperature of 120 ℃, cooled for 1h and then baked for 1h, transferred into a drier for cooling to the room temperature, and weighed. And calculating the content of the water extract. The results are given in Table 3 below.

TABLE 3 measurement of water extract

As can be seen from Table 3, the water extract contents of the tea bags of examples 1-3 are higher than those of comparative examples 9-10 and higher than those of comparative examples 9-26%, and the water extract content of comparative example 9 is slightly weaker than that of the examples due to the slightly larger particle size and insufficient dissolution during the extraction process; the water-soluble dissolution rate of the comparison example 10 is only 32%, and the water-soluble dissolution rate is obviously less than that of each example because the particle size is too fine, the specific surface area of the medicinal powder is too large, the adsorption effect is enhanced, the diffusion is influenced, the thickening phenomenon is easily generated in the extraction process, the extraction efficiency is influenced, and the extract is difficult to dissolve out, so that the particle size of the powder is obviously less than that of each example.

Dissolution rate test

Precisely weighing about 3.0g of the tea bags of examples 1-3 and comparative examples 9-10, placing in a conical flask, precisely adding 50ml of water, weighing, heating and refluxing for 10min, cooling, weighing again, supplementing the lost weight with water, shaking up, filtering, precisely weighing 25ml of the subsequent filtrate, evaporating to dryness, dissolving methanol to a constant volume of 10ml, and measuring the content of the dissolved components in the solution, which is shown in Table 4.

The results are shown in Table 4 below.

TABLE 4 dissolution test results

As can be seen from Table 4, the dissolution rates of chlorogenic acid and luteolin in the tea bags of examples 1-3 are higher than those of the control examples 9-10, and the dissolution rate of chlorogenic acid and luteolin in the extraction process is slightly lower than that of the examples due to the slightly larger particle size of the control example 9; the dissolution rates of chlorogenic acid and luteolin in the comparison example 10 are only 38.9% and 37.2%, and considering that the dissolution rates of chlorogenic acid and luteolin are obviously less than those in the examples because the particle size is too fine, the specific surface area of the medicinal powder is too large, the adsorption effect is enhanced, the diffusion is influenced, the thickening phenomenon is easily generated in the extraction process, the dissolution efficiency is influenced, and the components of chlorogenic acid and luteolin are not easily dissolved out, so that the particle size of the powder has influence on the dissolution effects of chlorogenic acid and luteolin.
