[Abstract]:An asexual Paecilomyces cicadae (Miq.) Samson parasitic on the fungal peduncle of the cicada Cicada flammata Dist larva and the dry complex of the corpse and the corpse of the larvae of Cordyceps cicadae Shing. C. parasitic on the dry complex of the sons and larvae of the larvae of the family moth. < Chinese Pharmacopoeia > included in the Cordyceps sinensis. Cicadas are included in the local standard < Sichuan traditional Chinese medicine standard >. Cicadas are mainly produced in Jiangsu, Zhejiang, Fujian, Sichuan, Tibet and other places, and the winter insect and summer grass are mainly distributed in Qinghai, Tibet, Sichuan, Yunnan, Gansu. The cicadas and Cordyceps sinensis belong to the family of ergodaceae and have similar pharmacological effects. Modern medical studies have shown that cicadas and Cordyceps are both effective in the treatment of renal failure, enhancing immune function, anti fatigue, and anti-tumor activity. The rapid and sensitive HPLC-MS/MS method has been established for the simultaneous determination of different HPLC-MS/MS methods. The content of 13 nucleosides in the 20 batches of cicadas and 12 batches of Cordyceps sinensis, and the content of the 10 batches of cicadas and 6 batches of Cordyceps, and the similarities and differences in the different parts of the two kinds of medicinal materials were compared. The content of the main nucleoside components in cicadas and the winter worm and summer grass were compared. The content of glycosides in different medicinal parts of two species of Cordyceps, preliminary discussion on the feasibility of cicadas substitutes for Cordyceps sinensis. At present, only the standard of Chinese medicinal materials in Sichuan province has been carried out, and the contents include only characters, identification and examination. The standard requirement of the national pharmacopoeia >2015 edition is that the quality standards of cicadas are perfected from characters, identification (thin layer), examination (water, total ash, acid insoluble ash and Leach), characteristic atlas and content determination. The first part is based on the comparison of the main nucleosides in cicadas and summer grass based on liquid chromatography-use Technology: the establishment of HPLC-MS/MS The content of nucleosides in cicadas and Cordyceps sinensis 13 was measured simultaneously, and the difference of nucleoside contents in different medicinal parts of the same medicine was also compared. Methods: using COSMOSIL Packed Column 5C18-PAQ (4.6 x 250 mm, 5 m) column, methanol -0.05% formic water as the flow phase, gradient elution, flow rate of 0.8 mL/min, and sample volume 20 L, column The temperature was 40 degrees centigrade. Mass spectrometry was detected by multi reaction monitoring (MRM) model, ESI source and positive ion mode. Source injection voltage (IS) was 5500 V; atomization temperature was 650; atomization gas (GS1, N_2): 4.14 x 10~5 Pa; auxiliary gas (GS2, N_2): 4.48 x 10~5 Pa; 1.72 X: 1 The relationship between the peak area and concentration of the 3 nucleosides was good in determining the concentration range. The precision, accuracy, stability, detection limit and quantitative limit of the correlation coefficient R2 > 0.9990. were all conformed to the requirements. The average recovery rate of 95.9-103.4%. samples showed that 13 nucleosides in cicadas and Cordyceps sinensis from different habitats The relative content and absolute content vary greatly, and the total content of 13 nucleosides in Cordyceps sinensis is obviously higher than that of cicada cicada, but the highest content of the two kinds of medicinal herbs is uridine. By comparing the total content of 13 species in the different medicinal parts of the two species of Cordyceps, namely the larvae and the fruiting bodies, they are found in the cicadas and the winter insects. It is the first time that the content of 13 nucleosides in cicadas and Cordyceps sinensis is determined by HPLC-MS/MS method, which is simple, sensitive and strong, and compares the difference of nucleoside content in the different medicinal parts of two kinds of Cordyceps, which is a substitute for the winter insect of cicadas. The second part of cicadas quality standard research objective: to establish the quality standard of cicadas, to provide the basis for the comprehensive quality control of cicadas in different sources. Methods: through the literature review of the cicadas, according to the four general rules of Chinese Pharmacopoeia >2015 edition, and reference to the traditional Chinese medicine in Sichuan Province. Material standard > for the 10 batch of cicadas, identification (TLC identification), examination (water, total ash, acid insoluble ash, alcohol soluble extract), the establishment of characteristics and content determination. Results: 1. determine the basis and character.2. identification of cicadas: TLC can identify 5 main spots with clear color, and the separation degree reaches the requirement. And the separation condition is affected by the temperature and humidity of small.3. examination: the result of water determination is 6.1%~11.6%; the result of determination of total ash is 5.5%~15.5%; the result of acid insoluble ash determination is 2.0%~10.5%; the determination result of the extract is 39.4%~45.6%.4. characteristic Atlas: the determination of the characteristic Atlas of the cicadas is.5. content determination: the mass concentration of uridine in 2.68~ There is a good linear relationship with peak area in the range of 16.13 g/m L, the regression equation is Y=0.833X-0.084 (R2=0.9999), the rate of addition recovery is 98.30%~101.4%, the content of uridine is 0.095%~0.172%. conclusion: the identification method of thin layer chromatography with good specificity and durability is established, and the water, total ash, acid insoluble ash and alcohol soluble extract are formulated. A simple and stable characteristic map and content determination method were established for the quality control of cicada flower.
