Description

Technical Field

[0001] The invention relates to the technical field of Chinese medicine processing, in particular to a processing method for reducing the toxicity of rhizoma arisaeodorae. Background Art

[0002] Arisaema is the dried tuber of Arisaema, Arisaema heterophyllum or Arisaema mandshurica, which belong to the Araceae family. Chinese medicine believes that Arisaema is bitter, pungent, warm and poisonous. It enters the lung, liver and spleen meridians, and has the effects of drying dampness and resolving phlegm, dispersing nodules and reducing swelling, and dispelling wind and stopping spasms. It is used externally to treat carbuncle, snake and insect bites. However, the raw decoction pieces of Arisaema are highly toxic and irritating, which manifests as a strong sense of numbness in the tongue and sore throat. When the raw powder is taken up to 2g, throat edema and loss of voice will occur, causing harm to the patient. Therefore, it is necessary to be cautious when taking Arisaema that has not been processed. In order to make it safe and effective, the Chinese medicine industry often uses Chinese medicine processing technology to reduce its toxicity.

[0003] The traditional processing method of Arisaema is mostly the replication method, which refers to adding one or several auxiliary materials to the selected Chinese medicinal materials, and repeatedly processing them to a specified degree according to the prescribed procedures, or soaking, soaking, bleaching, or steaming or multiple methods. It is mainly suitable for highly toxic drugs, the toxicity of which can be reduced or eliminated after replication, such as Pinellia, Arisaema, and Rhizoma Aconiti Lateralis. This method often uses a variety of auxiliary materials. The selection of different auxiliary materials for processing drugs can have different effects on the performance of the drugs. Studies have shown that the toxic and irritating components in Arisaema are calcium oxalate needle crystal bundles and lectin toxic proteins. After processing according to the processing method specified in the Pharmacopoeia of the People's Republic of China, the toxic needle crystals and toxic proteins originally contained in Arisaema are destroyed. Because after processing with multiple auxiliary materials, the calcium oxalate needle crystals are dissolved, and the lectin toxic proteins connected to the toxic needle crystals are denatured and lose their activity. The content of both is greatly reduced compared with the raw product. However, the replication method has the disadvantages of long processing cycle, complex processing technology, and a wide variety of processing auxiliary materials. Moreover, alum is often used as an auxiliary material for detoxification during the preparation of alum. If patients take alum-processed arisaema for a long time, excessive intake of aluminum ions will cause damage to brain neurons. In addition, the arisaema prepared by the traditional replication method has the disadvantage that the quality evaluation of arisaema is difficult to standardize. Summary of the invention

[0004] In order to solve the above problems, that is, to solve the problems raised by the above background technology, the present invention proposes a processing method for reducing the toxicity of Arisaema cinerea, and the specific technical scheme is as follows:

[0027] Calculation of active ingredient content: Take the mixed reference solution of the three index components and prepare five series of reference solution concentrations. Inject and measure according to the chromatographic conditions to obtain the standard curve equations of the three components. Determine the peak area of ​​each batch of samples according to the standard curve drawing method, and calculate the content of the active ingredient in the test solution according to the standard curve.

[0028] ② The content of total flavonoids and total saponins in the prepared slices and the pharmacopoeia slices was determined by visible light-ultraviolet spectrophotometry

[0029] Determination of total flavonoids

[0030] Preparation of reference solution: Take an appropriate amount of apigenin reference solution and add 60% ethanol to make the mass concentration of apigenin reference solution be 15.21 μg / ml.

Each sample was measured three times and the average value was taken.

[0037] Toxicity and irritation evaluation

[0038] ① Determination of residual aluminum ions

[0039] Take about 2g of sample powder (passed through No. 4 sieve), accurately weigh it, put it in a crucible, heat it slowly until it is completely carbonized, then gradually increase the temperature to 450℃, incinerate for 4h, cool it, carefully add 10mL of dilute hydrochloric acid to the crucible, cover the crucible with a watch glass, heat it in a water bath for 20min, rinse the watch glass with 5ml of hot water, add the washing liquid into the crucible, filter it, wash the filter residue and crucible with 25ml of water in several times; combine the filtrate and washing liquid, add 1 drop of methyl red indicator solution, shake well, then add ammonia test solution until the solution changes from red to yellow, add acetic acid-ammonium acetate buffer solution (pH 6.0), accurately add 25ml of disodium ethylenediaminetetraacetic acid titration solution (0.05mol / L), boil for 3-5 minutes, cool it, add 1ml of xylenol orange indicator solution, titrate with zinc titration solution (0.05mol / L) until the solution changes from yellow to orange-red, and correct the titration result with a blank test. Each 1 ml of disodium ethylenediaminetetraacetic acid titration solution (0.05 mol / L) is equivalent to 23.72 mg of potassium aluminum sulfate [KAl(SO4)2·12H2O]. Each sample was measured three times and the average value was taken.

[0040] ② Changes in the rigid structure of calcium oxalate needle crystal bundles

[0041] Take about 0.5 g of sample powder (passed through No. 4 sieve), dip a small amount of powder with a toothpick and stick it on the observation platform with tape. After vacuum drying, spray gold, observe under a scanning electron microscope and take pictures.

[0042] ③ Determination of the agglutination effect of two processed extracts of Arisaema confusa on rabbit red blood cells

[0043] Take 1.0g of sample powder and pass it through a 80-mesh sieve, place it in a centrifuge tube, add 10mL of 0.01M PBS solution, soak it at 4℃ overnight, take it out, centrifuge it (8500r / min, 5min), and take the supernatant, which is the protein extract of processed Arisaema. Dilute the extract with an equal amount of PBS (the dilution factor is 2 0 , 2 1 , 2 2 , 2 3 , 2 4 ). 40 μL of 2% rabbit red blood cell suspension was added to each well of a 96-well V-type blood coagulation plate, and 40 μL of processed protein extract was added to each well.

[0044] Slightly shake and place at room temperature for 2 hours before observing with the naked eye. When there is no agglutination, the red blood cells are deposited at the bottom of the V-shaped hole as large red dots. When there is agglutination, they are net-like and do not sink. The agglutination activity is expressed as the minimum amount of agglutinin protein or the maximum dilution multiple of agglutinin protein when agglutination occurs. PBS is used as a blank control.

[0045] Efficacy evaluation

[0046] ①Evaluation of the effects of two processed products of Arisaema consanguineum on promoting sputum discharge

[0047] Kunming mice weighing 20±2g, half male and half female, were randomly divided into 4 groups after adaptive feeding for one week: blank group, raw product group, pharmacopoeia product group, and new craft product group, with 10 mice in each group. Except for the blank group, mice in each group were intraperitoneally injected with 0.4mg / mL lipopolysaccharide injection at a dose of 0.08mg (lipopolysaccharide) / 20g (mouse weight) according to their body weight. Ten minutes later, ovalbumin saline solution with a concentration of 0.6mg / ml was intraperitoneally injected at a dose of 0.12mg (ovalbumin) / 20g (mouse weight). The blank group mice were injected with the same dose of saline. On the second day, the mice in the drug-treated group were placed in a bell jar filled with concentrated ammonia for 20 minutes every morning, noon and evening, and then placed in an ice water bath to swim for 20 minutes. Starting from the third day, the drug-treated group was gavaged with three sample decoctions, and the blank group was given an equal volume of saline for 3 consecutive days. Before euthanasia, mice in each group were fasted for 12 hours. On the morning of the 6th day, mice in each group were injected with 0.5% phenol red PBS solution through the tail vein. After 30 minutes, the mice were euthanized and the trachea was immediately separated from the bronchial branch of the thyroid cartilage, tied with silk thread, and 0.5 ml of 5% NaHCO3 solution was drawn with a 1 ml syringe to irrigate the respiratory tract three times. Finally, the irrigating fluid was drawn out and injected into a small test tube. The above process was operated three times and the elution was combined. The absorbance was measured at 546 nm by ultraviolet spectrophotometry. The above results were statistically analyzed using IBM-SPSS27.0 version software. When the sample data met the normal distribution and variance homogeneity, the statistical analysis method was ANOVA single-factor analysis of variance.

[0048] ② Evaluation of the anticonvulsant effects of two processed products of Arisaema consanguineum

[0049] 40 Kunming mice weighing 25-30g, half male and half female, were randomly divided into 4 groups. The mice were given intragastric administration once a day for 3 consecutive days, and 40 minutes after the last intragastric administration, 0.5 mg / mouse of strychnine nitrate was subcutaneously injected. The time of convulsion and the time of death of mice were recorded by falling over and stretching the hind legs as indicators. The above results were statistically analyzed using IBM-SPSS27.0 version software. When the sample data met the normal distribution and variance homogeneity, the statistical analysis method was ANOVA single-factor analysis of variance.

[0050] The comparison results are as follows:

[0051] (1) Appearance and properties of medicinal pieces

[0052] Figure 2 The raw Arisaema, Arisaema slices prepared by pharmacopoeia method and Arisaema slices prepared by extrusion puffing method are shown in the table. Figure 2 It can be seen that compared with the Arisaema consanguineum slices prepared by the pharmacopoeia method, the slices prepared by the new process are lighter in color, light yellow-white, with a consistent and uniform color, and are in the shape of strips with uniform thickness.

[0053] (2) Quality evaluation results

[0054] Figure 3 This is the HPLC chart of three indicative components in Arisaema.

[0055] Table 1 Determination results of various components in processed products of Tiannanxing (n=3)

[0056]

[0057] As can be seen from Table 1, the contents of total flavonoids, total saponins, trigonelline, schaftoside and isoschaftoside in the Arisaema confusa prepared by the method of the present invention are all higher than those in the prepared product according to the pharmacopoeia method.

[0058] (3) Toxicity and irritation evaluation results

[0059] ① Determination results of aluminum ion content

[0060] Table 2 Determination results of aluminum ion content in processed products of Tiannanxing (n=3)

[0061]

[0062] As can be seen from Table 2, the Arisaema confusa prepared by the method of the present invention does not contain aluminum ions, while the aluminum ion content in the prepared Arisaema confusa by the pharmacopoeia method is relatively high.

[0063] ② Agglutination effect on rabbit red blood cells

[0064] Figure 4 This is a graph showing the results of the agglutination effect of PBS extracts of raw and processed Arisaema consanguineum on rabbit red blood cells.

[0065] from Figure 4It can be seen that the protein extract of raw arisaema can agglutinate rabbit red blood cells, indicating that the separated sample contains lectin protein, and there is no precipitation when 2% rabbit red blood cells are added to the protein extract of raw arisaema, indicating that the arisaema has not been processed and the agglutinin toxic protein has strong activity; dot-shaped dark red precipitates can be observed at the bottom of the V-type blood agglutination plate corresponding to the pharmacopoeia group, and the dots gradually increase with the increase of the dilution multiple, indicating that the agglutination activity of the pharmacopoeia group is lower than that of raw arisaema, and the toxicity is weakened, with only a little agglutination activity, which proves the rationality of the pharmacopoeia processing method; after 2% rabbit red blood cells are added to the sample extract obtained by the extrusion puffing method, round dot-shaped precipitates can be seen at the bottom, and their size is consistent with the size of the blank precipitate dots, indicating that the extrusion puffing method inactivates the agglutinin, and the agglutinin inactivation is more thorough than the pharmacopoeia method, which can play a detoxification role, proving the feasibility of applying the extrusion puffing technology to the processing of arisaema.

[0066] ③ Changes in the morphology of the irritating ingredient ammonium oxalate needle crystal bundles

[0067] Figure 5 These are morphological photos of calcium oxalate needle crystal bundles, the irritating ingredient in raw and processed Arisaema consanguineum.

[0068] Depend on Figure 5 It can be seen that the tips of the calcium oxalate needle crystals of raw Arisaema are sharp, and the calcium oxalate needle crystals exist in bundles, which are highly irritating; the calcium oxalate needle crystals of Arisaema prepared by the pharmacopoeia method are broken and scattered, and there are calcium oxalate needle crystal fragments attached to the surface of gelatinized starch granules, which greatly reduces the toxicity and irritation compared with raw Arisaema; the samples obtained by the extrusion puffing method did not show bundles or broken calcium oxalate needle crystals under scanning electron microscopy, and there were no scattered calcium oxalate needle crystals on the surface of the starch granules after puffing. It can be seen that the calcium oxalate needle crystal bundles were crushed or dissolved under the physical action of extrusion puffing.

[0069] (4) Efficacy evaluation results

[0070] ①Evaluation of drug efficacy in promoting sputum discharge

[0071] Table 3 Results of the measurement of the effect of Arisaema on expectorant effect

[0072]

[0073] The results of LSD and SNK pairwise comparison analysis showed that compared with the blank group, the different processing products of Arisaema consanguineum had significant differences in promoting sputum discharge, P < 0.01. Compared with the raw product group, the pharmacopoeia product was weaker in promoting sputum discharge, and the difference in efficacy was significant, P < 0.05. Compared with the product group of the method described in the present invention, the pharmacopoeia product in the group also had a weaker effect on promoting sputum discharge, which was not as good as the new process product, P < 0.05, and the difference was significant.

[0074] ②Evaluation of anticonvulsant efficacy

[0075] Table 4 Comparison of anticonvulsant effects of different processed products of Arisaema consanguineum

[0076]

[0077] The results of LSD and SNK pairwise comparison analysis showed that compared with the blank group, the different processing products of Arisaema consanguineum had significant differences in promoting sputum discharge, P < 0.01. Compared with the raw product group, the pharmacopoeia product was weaker in promoting sputum discharge, and the difference in efficacy was significant, P < 0.05. Compared with the processing product group described in the present invention, the pharmacopoeia product in the group also had a weaker effect on promoting sputum discharge, which was not as good as the processing product described in the present invention, P < 0.05, and the difference was significant.

[0078] In summary, the method of the present invention solves the problems of the current preparation process of Arisaema confusa products being complicated and cumbersome, having a long cycle and having more auxiliary materials. The instantaneous extrusion temperature is 110-120°C, which retains the content of the index components in Arisaema confusa medicinal materials to the greatest extent, achieves the purpose of reducing toxicity while maintaining efficacy, and can reduce the toxicity of Arisaema confusa such as tongue numbness and throat irritation to a minimum. In terms of promoting sputum discharge and anticonvulsant effects, it is superior to the pharmacopoeia method and reduces the production cost of Arisaema confusa.
