Problems solved by technology

[0006] Although Cistanche and Cistanche, Cistanche, and Cistanche can be distinguished in appearance, but with the deepening of processing, after the medicinal materials of Cistanche are crushed and milled, it is impossible to directly distinguish different qualities and different qualities from the appearance. Cistanche herbs, which provide opportunities for unscrupulous traders to mix non-medicinal Cistanche herbs into Cistanche herbs, or use low-quality Cistanche herbs instead of high-quality Cistanche herbs
Simultaneously, because the loss of volatile organic matter after Cistanche deserticola pulverization also can reduce the quality of Cistanche deserticola to a certain extent
Therefore, it is necessary to provide a method capable of identifying the quality of Cistanche deserticola, which solves the problem that medicinal material processing manufacturers have no effective identification method for the quality of Cistanche deserticola medicinal material that is initially processed into powder.

Embodiment 1

[0038] Example 1 Establishment of Standard Spectrum Atlas

[0039] The sources of the standards are shown in Table 1:

[0040] Table 1

[0041] Numbering sample Origin 1 Cistanche oleifera powder Ordos, Inner Mongolia 2 Cistanche powder Ordos, Inner Mongolia 3 Xinjiang Cistanche Cistanche Powder Xinjiang Hotan area

[0042] The sample powder of fresh Cistanche deserticola from the origin is used as the standard, and it is quickly sealed and stored after milling to ensure the least loss of flavor volatile substances.

[0043] Establishment of Evaluation Criteria: Difference Analysis of Volatile Organic Compounds in Different Quality of Cistanche deserticola

[0044] 1) Take 0.5 g each of the standard No. 1 Cistanche oleifera powder, the standard No. 2 blood Cistanche powder, and the standard No. 3 Cistanche Cistanche powder, and place them in a 20mL headspace bottle for automatic headspace injection after incubation. , the incubation...

Embodiment 2

[0062] 1) Sample processing: take 0.5g of sample No. 1 Cistanche powder and incubate it in a 20mL headspace bottle, and then inject the sample through automatic headspace;

[0063] 2) Sample detection: pass The flavor analyzer conducts gas-phase ion migration detection on sample No. 1 Cistanche powder to obtain the detection data;

[0064] 3) Sample analysis: According to the detection data, make a gas phase ion mobility spectrum, and use the analysis software and plug-in to compare the similarity analysis.

[0065] like Figure 8 Shown is the qualitative analysis of volatile organic compounds of sample No. 1 (select a parallel sample for drawing), it can be found that the qualitative compounds contain acetone, hexanal, pentanal, E-2-heptanal, E-2-octanal, etc. It can be judged that the quality of the Cistanche deserticola powder is close to that of the Cistanche deserticola powder.

Embodiment 3

[0067] 1) Sample processing: take 0.5g of sample No. 2 Cistanche powder and incubate it in a 20mL headspace bottle, and inject the samples through automatic headspace;

[0068] 2) Sample detection: pass The flavor analyzer conducts gas-phase ion migration detection on sample No. 1 Cistanche powder to obtain the detection data;

[0069] 3) Sample analysis: According to the detection data, make a gas phase ion mobility spectrum, and use the analysis software and plug-in to compare the similarity analysis.

[0070] Figure 9 Qualitative analysis of volatile organic compounds for sample No. 2. It can be found that the qualitative compounds are ethanol, 2-methylbutanal, 3-methylbutanal, γ-butyrolactone, n-propanol, ethyl acetate, 2,3-butanedione, 2-methylpropane Alcohol and acetoin, etc. It can be judged that the volatile substances of the Cistanche deserticola powder are basically the same as those of the standard No. 2 Cistanche deserticola powder, and its quality is consist...

Abstract

The invention relates to a method for identifying cistanche powder with different qualities, which comprises the following steps: 1) sample treatment: taking 0.5 g of cistanche powder, placing the cistanche powder in a 20mL headspace bottle for incubation, and carrying out automatic headspace sample injection; 2) sample detection: performing gas phase ion migration detection on the cistanche sample through a flavor analyzer to obtain detection data; and 3) sample analysis: making a gas phase ion mobility spectrometry according to detection data, and performing similarity analysis by using analysis software and plug-in comparison. According to the identification method provided by the invention, the cistanche deserticola with different qualities is rapidly identified by detecting the variety and the content of the volatile substances in the sample for differential analysis.

Description

technical field [0001] The invention belongs to the field of traditional Chinese medicine, and relates to a method for identifying cistanche powder of different qualities. Background technique [0002] The traditional Chinese medicinal material Cistanche is the dry, scaly stem of Cistanche deserticola Y.C.Ma or Cistanche tubulosa (Schenk) Wight of the Lidanaceae plant. It is recorded in "Chinese Pharmacopoeia (2015)": Cistanche deserticola is flat cylindrical, slightly curved, 3-15cm long and 2-8cm in diameter. Surface tan or gray-brown, densely covered imbricate succulent scale leaves, usually the apex of the scale leaves has been broken. Weight, hard, slightly flexible, not easy to break, brown section, with light brown dotted vascular bundles, arranged in wavy rings. Gas micro, sweet, slightly bitter. Cistanche Cistanche is fusiform, flat spindle or flat cylindrical, slightly curved, 5-25cm long and 2.5-9cm in diameter. Surface tan to dark brown. The section is granu...
