Problems solved by technology

For example, "The Pharmacopoeia of the People's Republic of China" 2010 Edition, Part 1 and "Technical Specifications for Health Food Inspection and Evaluation" 2003 Edition of the Ministry of Health of the People's Republic of China are all involved, but the inventor of this patent was in the verification test for the determination of adenosine in cicadae samples It is found that the extraction and processing method of adenosine in the above method will lead to a low extraction rate of adenosine and more interference

Embodiment 1

[0108] A sample preparation method for cicadae detection, the method comprises the following steps: take cicadae fruiting body powder 0.2g, accurately weighed, put 20mL stopper test tube, add 5mL distilled water accurately, ultrasonic (40KHz) process 30 minutes, take out , Immediately add 5mL of methanol precisely, mix well, pass through a 0.22μm microporous membrane, and take the subsequent filtrate to obtain.

Embodiment 2

[0110] The sample preparation method is basically the same as in Example 1, except that 4.5 mL of methanol is precisely added, and the extraction method is reflux extraction for 30 min.

Embodiment 3

[0112] The sample preparation method is basically the same as in Example 1, except that 4 mL of methanol is precisely added.

Abstract

The invention relates to a detection method of isaria cicadae miquel. According to the detection method, high performance liquid chromatography is adopted. The detection method comprises following steps: a, determination of chromatographic conditions, wherein an acetonitrile-dihydric phosphate solvent system is taken as a mobile phase, and isocratic elution is adopted; b, a reference solution is prepared, wherein an adenosine reference substance is mixed with a solvent so as to obtain the reference solution; c, a sample solution to be detected is prepared, wherein an isaria cicadae miquel sample to be detected is mixed with a solvent so as to obtain the sample solution to be detected; and d, measuring is carried out, wherein the reference solution and the sample solution are injected into a liquid chromatograph respectively for measuring. The detection method can be used for detecting isaria cicadae miquel sporocarp, spore powder, mycoplasm, or extracts or preparations of isaria cicadae miquel sporocarp, spore powder, and mycoplasm; the detection method is simple; few influences are caused; and stability is high.

Description

technical field [0001] The invention relates to a detection method of traditional Chinese medicine, in particular to a detection method of cicadae. Background technique [0002] Cicadae (Isaria cicadae Miquel) belongs to the kingdom Fungi, phylum Ascomycota, subdivision Discomycotina, class Copromycetes, order Hypocreales, family Cordyceps, genus Isaria. [0003] Cicada is a precious Chinese medicinal material in my country, and it is a kind of Cordyceps fungus that parasitizes on cicadas (commonly known as "cicadas"). Its medicinal use has a history of more than 1,000 years. It is one of the traditional precious medicinal materials in my country and has various medicinal values. The main ingredients are: adenosine, cordyceps polysaccharide, cordycepic acid (mannitol), cordycepin, uracil, sterols, alkaloids, vitamins, inorganic salts, mineral elements, etc. [0004] Cicada has the function of regulating human immunity, improving appetite, promoting sleep, and enhancing the...
