[0027] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0029] Spectroscopic technology can qualitatively or quantitatively analyze the atomic or molecular composition of a sample through the reflection, transmission, and emission spectra of the sample, and has been widely used in many fields such as chemistry, industry, agriculture, and medicine. The chemical components in Chinese medicinal materials vary significantly in type, composition, and content due to the influence of factors such as the growth environment and soil geology of the origin. They can be used as characteristic indicators and important references for origin identification. The spectrum of Chinese medicinal materials can provide an important basis for origin tracing. At the same time, spectral technology has the advantages of being easy and fast to operate, and has great potential in high-throughput identification of the origin of Chinese medicinal materials.

[0030] like Figure 1 As shown, the embodiment of the present application provides a method for tracing the origin of Chinese medicinal materials, which specifically includes:

[0031] S1: extracting features from the spectral data set of the sample according to a feature extraction algorithm to obtain spectral feature values ​​that are highly correlated with the origin of the Chinese medicinal materials; the spectral data set is a full spectrum consisting of multiple spectral bands.

[0032] S2: Processing the spectral characteristic values ​​to obtain spectral characteristic mapping values.

[0033] S3: According to the coding table, the spectral feature mapping value is converted to determine the encrypted Chinese herbal medicine sample origin code; the encrypted Chinese herbal medicine sample origin code is a QR code or a Code128 barcode.

[0034] S4: Based on the coding table, the sample origin identification result is determined according to the encrypted Chinese medicinal material sample origin code and the origin identification classification model; the origin identification classification model is constructed with the spectral feature mapping value as the input variable and the sample origin label as the output variable; the sample origin label is the sample origin identification result.

[0035] Further, in an exemplary embodiment, step S1 may be replaced by the following steps.

[0036] S101: Collect a spectral data set of a sample using a laser induced breakdown spectroscopy detection system.

[0037] A method for tracing the origin of Chinese medicinal materials aims to protect the focus of the spectrum by screening characteristic spectral lines, mapping characteristic values ​​and encoding them into Chinese medicinal materials origin codes, combined with machine learning classification models, to achieve rapid identification of Chinese medicinal materials.

[0038] Laser-induced breakdown spectroscopy (LIBS) detection platform was used to obtain LIBS spectrum data of the samples.

[0039] The samples of Panax notoginseng from 6 production areas (Chuxiong, Kunming, Qujing, Wenshan, Honghe and Yuxi) were used as the research objects. Panax notoginseng was dug after three years of planting, and the surface impurities were cleaned, dried, ground, and passed through the pharmacopoeia No. 4 sieve to obtain the Panax notoginseng powder sample. Weigh 0.2g of powder sample, use a hydraulic press to continuously pressurize for 30s at 20MPa pressure, and press the powder into a disc sample with a diameter of 13mm and a thickness of 1mm for LIBS spectrum acquisition. In this embodiment, a total of 420 samples were prepared and randomly divided into training set, validation set and prediction set according to the ratio of 3:1:1, which were 252, 84 and 84 respectively.

[0040] The sample spectrum is collected by a laser-induced breakdown spectroscopy detection system, which is mainly composed of a pulsed laser, a spectrometer, a detector, a delay generator, an electric translation stage, an optical path system, etc. The laser (Beamtech, Beijing, China) provides laser pulse energy for the LIBS system; the constructed optical path system focuses the laser to 2 mm below the sample surface; the electromagnetic wave signal radiated by the plasma is split by the spectrometer, and the photodetector converts the optical signal into an electrical signal, which is transmitted to the computer for reading and recording. In this embodiment, a CT monochromator SR500i (Andor, Belfast, UK) is selected, with a band range of 209.97-230.98 nm and a total of 1024 variables; a digital delay generator (Stanford Research Systems, California, USA) is used for timing control between the laser and the ICCD detector; and the electric translation stage realizes the acquisition of LIBS signals at different sites of the sample. In this embodiment, the parameters of the LIBS detection system are set as follows: delay time 2 μs, integration time 8 μs, laser energy 40 mJ, and continuous hitting of a single site 9 times. The moving path of the XYZ electric translation stage was set to a 2×3 matrix. By controlling the movement of the sample, LIBS spectral data at 6 different sites were collected. A single site was laser-struck 9 times, and the LIBS spectrum of the sample was the average of 54 (2×3×9) spectra.

[0041] S102: Screening spectral feature values ​​that are highly correlated with the origin of the Chinese medicinal materials from the full spectrum according to a competitive adaptive weighted sampling method and a continuous projection algorithm.

[0042] The spectral dataset was randomly divided into training set, validation set and test set. Based on the training set and validation set, two feature extraction algorithms, competitive adaptive reweighted sampling (CARS) and successive projection algorithm (SPA), were used to screen the characteristic bands that were highly correlated with the origin of Chinese medicinal materials from the full spectrum, and the redundant bands were eliminated.

[0043] The sample LIBS spectra were preprocessed by area normalization to eliminate the interference of spectral fluctuations. Based on the training set and the validation set, the characteristic bands highly related to the origin of Panax notoginseng were screened in turn by two feature extraction algorithms, namely, competitive adaptive reweighted sampling (CARS) and successive projection algorithm (SPA), and the redundant bands were eliminated. Finally, 15 characteristic bands were obtained, and the wavelengths were 213.99, 214.80, 214.86, 215.09, 216.47, 217.97, 219.96, 221.94, 222.86, 228.30, 229.30, 229.73, 230.40, 230.47, and 230.98 nm.

[0044] Further, in an exemplary embodiment, step S2 may be replaced by the following steps.

[0045] S201: Using formula x minmax =(xx min ) / (x max -x min ) performs normalization processing on the spectral characteristic values ​​to obtain normalized spectral characteristic values; wherein, x minmax is the normalized spectral characteristic value; x is the unprocessed spectral characteristic value; x min is the minimum value among all the spectral characteristic values; x max is the maximum value among all the spectral characteristic values.

[0046] S202: Mapping the normalized spectral characteristic values ​​to the interval [0, N] at equal intervals to obtain spectral characteristic mapping values, wherein N is the number of mapping intervals, which is user-defined within the positive integer range of [20, 95].

[0047] The normalized eigenvalue is then multiplied by N (N≤95, N is an integer) and rounded off to an integer value interval of [0, N] as the spectral feature mapping value.

[0048] Further, in an exemplary embodiment, step S3 may be replaced by the following steps.

[0049] S301: Convert the spectral feature mapping value into an ASCII code string according to a coding table.

[0050] S302: Determine the encrypted origin code of the Chinese herbal medicine sample according to the ASCII code string.

[0051] The spectral feature mapping value of the Chinese herbal medicine sample whose origin needs to be identified is converted into an ASCII code string using a custom coding table, and then a QR code or Code128 barcode is generated as the encrypted origin code of the Chinese herbal medicine sample.

[0052] Further, in an exemplary embodiment, step S4 may be replaced by the following steps.

[0053] S401: Based on the coding table, the encrypted origin code of the Chinese medicinal material sample is decoded to determine the spectral feature mapping value.

[0054] S402: Input the spectral feature mapping value into an origin identification classification model to determine a sample origin identification result.

[0055] Based on the training set and validation set of samples, with spectral feature mapping values ​​as input variables and sample origin labels as output variables, a support vector machine (SVM)-based origin identification and classification model was established, and the origin classification accuracy of the model was verified through the test set.

[0056] The user can scan the sample origin code to read the sample origin characteristic spectrum code, and convert it into a spectrum characteristic mapping value based on the code table. The sample origin identification result can be output by inputting the sample spectrum characteristic value into the origin identification model. The process is encrypted to prevent the identification result from being forged, and it is convenient for users to scan the code for verification, which is easy to operate and the result is reliable.
