Embodiment 1

[0142] Establishment of a method for identification and classification of tangerine peel.

[0143] 1. Sample preparation.

[0144] Take an appropriate amount of different types of samples, crush them, weigh about 0.2g, put them in a 20ml headspace sampling bottle, and obtain.

[0145] Among the above samples, there are 29 batches of standard tangerine peel and 16 batches of standard tangerine peel, 45 batches in total.

[0146] Second, detection.

[0147] Injector conditions: injection needle temperature is 85°C; injection volume is 0.5ml; stirring speed is 500rpm; incubation temperature is 60°C; incubation time is 10min.

[0148] GC-IMS coupled instrument conditions: chromatographic column is FS-SE-54-CB-1 (weak polar capillary column, length 15m, inner diameter 0.53mm); drift tube temperature (T1) is 45°C; gas chromatography column temperature (T2) is 70°C; inlet temperature (T3) is 80°C; inlet-column adapter temperature (T4) is 80°C; column-transfer tube adapter temperat...

Embodiment 2

[0161] A method for identifying and classifying tangerine peel.

[0162] 1. Sample preparation.

[0163] Take an appropriate amount of different types of samples, crush them, weigh about 0.2g, put them in a 20ml headspace sampling bottle, and obtain.

[0164] The above-mentioned samples are all commercially available, marked as 21 batches of tangerine peel, and 32 batches marked as tangerine peel, totaling 53 batches.

[0165] Second, detection.

[0166] Detect according to the method of embodiment 1.

[0167] 3. Data analysis.

[0168] The results of dynamic principal component analysis are as follows: Figure 4 As shown in the figure, the triangle legend represents the standard tangerine peel, the circular legend represents the standard tangerine peel, the square legend represents the sample marked as "wide tangerine peel", and the regular pentagonal legend represents the sample marked as "tangerine peel". According to detection data, the 53 batches of samples obtained ...

Embodiment 3

[0171] A method for identifying and classifying tangerine peel.

[0172] 1. Sample preparation.

[0173] Take an appropriate amount of dried and mature fruit peels from different sources, crush them separately, weigh about 0.2g respectively, put them in a 20ml headspace sampling bottle, and obtain the product.

[0174] The above-mentioned samples are all self-made, and are prepared by sun-drying tea branch orange peel, orange peel, orange peel, tribute orange peel, and emperor orange peel.

[0175] Second, detection.

[0176] Detect according to the method of embodiment 1.

[0177] 3. Data analysis.

[0178] The results of dynamic principal component analysis are as follows: Figure 6 As shown in the figure, the triangle legend represents standard tangerine peel, the circle legend represents standard tangerine peel, the regular hexagon legend represents tea branch orange samples, and the diamond legend represents samples from other sources. After comparative analysis of t...

Abstract

The invention relates to an identifying and classifying method and an identifying and classifying device of dried citrus reticulata peel, and belongs to the technical field of traditional Chinese medicine identification. The identifying and classifying method comprises the following steps: establishing a standard dried citrus reticulata peel database, namely taking a dried citrus reticulata peel sample, detecting by gas chromatography ion mobility spectrometry to obtain GC-IMS analytical data of standard dried citrus reticulata peel and establishing the standard dried citrus reticulata peel database; performing identifying judgment: detecting a dried orange peel sample to be detected according to a detection method of the dried citrus reticulata peel sample by using a gas chromatography ion mobility spectrometry instrument to obtain GC-IMS analytical data of the dried orange peel sample to be detected, extracting characteristic data therein, analytically comparing with the data in thestandard dried citrus reticulata peel database and judging to obtain the type of the dried orange peel sample to be detected. The identifying and classifying method is good in repeatability, simple, convenient and fast and is worthy of wide application.

Description

technical field [0001] The invention relates to the technical field of identification of traditional Chinese medicines, in particular to a method and device for identification and classification of tangerine peel. Background technique [0002] The authentic product of Guang Chen Pi is the dry and mature peel of Citrus reticulata ‘Chachi’, which is mainly produced in Xinhui, Guangdong, also known as Xinhui Chen Pi, and is one of the authentic medicinal materials in Guangdong. "Chinese Pharmacopoeia" divides the medicinal materials of tangerine peel into "tangerine peel" and "guang tangerine peel". There are still obvious differences between the two in clinical application and daily consumption. Compared with ordinary tangerine peel, tangerine peel has a higher content of volatile oil and more chemical components. According to traditional Chinese medicine, in addition to the effects of regulating qi and regulating the middle, drying dampness and invigorating the spleen, tange...
