Problems solved by technology

[0003] Panax notoginseng medicinal materials can be divided into three types according to their parts: main root, tendon and notch. For a long time, the raw medicinal materials have been judged by their appearance size, color, weight and taste. However, Sanqi lost its original appearance after being crushed. It cannot be identified, and the difference in the content of internal components among the various specifications and grades of Sanqi medicinal materials may affect the safety and effectiveness of clinical medication
[0004] Through market research, it is found that the source of the powder part of the commercially available Panax notoginseng powder decoction pieces is not clear, and the price is uneven, but the indicated dosage is 1-3g, so it is necessary to establish a source of the powder part of the Panax notoginseng powder decoction Rapid identification method to standardize the market price of Sanqi powder decoction pieces, guide the clinical dosage of Sanqi powder decoction pieces, and provide reference for the quality control and rational utilization of Panax notoginseng powder decoction pieces

Embodiment 1

[0019] Embodiment 1, detection of commercially available Panax notoginseng powder powder part source

[0020] (1) Detection method

[0021] Take the medicinal materials to be tested, place them in a quartz sample cup, fill an appropriate amount of sample to cover the bottom of the quartz sample cup, and collect near-infrared spectra with a near-infrared spectrometer. Spectral acquisition conditions: resolution 8cm -1 , the number of scans is 64 times, select 4400-4800, 5400-6600, 7800-10000cm -1 Three bands are scanned, cluster analysis (Cluster) is used as the calculation method, the discriminant classification method combining principal component analysis and Mahalanobis distance is adopted, and the first-order derivative of nine-point convolution and unit length normalization (dg1, nle ) as the pretreatment method, and finally use the scores of the main components PC1 and PC2 to identify the source of the powder of Panax notoginseng powder. Among them, when the principa...

Embodiment 2

[0026] Embodiment 2, detection parameter selection

[0027] (1) Spectrum information collection

[0028] Take the medicinal materials to be inspected: crush the medicinal materials of the main root, notches and tendons of Panax notoginseng, pass through a No. 6 sieve after crushing, put the powder in the quartz sample cup after sieving, and fill the sample with an appropriate amount until the bottom of the quartz sample cup is covered. Near-infrared spectra were collected with a near-infrared spectrometer. Spectral acquisition conditions: resolution 8cm -1 , the number of scans is 64 times, and the scan range is 4000~10000cm -1 , each sample was loaded repeatedly and scanned 3 times, the collected spectra are shown in figure 1 .

[0029] (2) Parameter screening

[0030] Import the collected 38 batches of samples into the analysis software NIRcal that comes with the instrument, divide the sample calibration set (C-set) and verification set (V-set) according to the ratio of...

Abstract

The invention discloses a detection method for a powder part source of commercially available pseudo-ginseng powder. A near infrared spectroscopy is adopted for detection, and the detection method comprises the following steps: taking to-be-detected crude drug powder, loading a sample and collecting a near infrared spectrum; preprocessing the spectrum unit length normalization and a nine-point convolution first-order derivative by taking a cluster analysis as a computing method, and identifying the powder part source of a commercially available sample according to a score value of main ingredients of the sample. The detection method is high in accuracy rate, convenient in operation and good in market application prospect.

Description

technical field [0001] The invention relates to a method for detecting the part source of commercially available Panax notoginseng powder powder, and belongs to the field of traditional Chinese medicines. Background technique [0002] Panax notoginseng is the dry root and rhizome of Panax notoginseng (Burk.) F.H.Chen of Araliaceae, mainly produced in Yunnan. Panax notoginseng powder is the processed product of the original medicinal material of notoginseng after being crushed. It is stipulated under the item of Sanqi powder in the 2015 edition of "Chinese Pharmacopoeia" that it has the functions of dispelling blood stasis, stopping bleeding, reducing swelling and relieving pain. For hemoptysis, hematemesis, carp blood, hematochezia, metrorrhagia, traumatic bleeding, chest and abdomen tingling, tumbling and swelling pain. As Panax notoginseng is popular in the market in the form of powder decoction pieces, Yunnan Provincial Food and Drug Administration has revised the standa...
