Embodiment 1

[0089] Embodiment 1, near-infrared spectrometry measures the menthol content of Peppermint medical material

[0090] (1) Medicinal material sample preparation: select 30 batches of mint medicinal materials, crush and sieve, and set aside

[0091] (2) Content determination:

[0092] The menthol content in the medical material is carried out gas phase determination, and assay method is as follows:

[0093] Take 4g of peppermint powder, weigh it accurately, put it in a round bottom flask, add 100ml of water, add water from the upper end of the detector to fill the scale part and overflow into the flask, add 3ml of cyclohexane, connect the reflux condenser, heat to boiling, keep Simmer for 3 hours, let cool, move the cyclohexane layer in the measuring device to a 25ml volumetric flask, wash the condenser tube, the inner wall of the volatile oil measuring device and the water layer with cyclohexane several times and move to the volumetric flask. Dilute to volume with hexane to ob...

Embodiment 2

[0107] Embodiment 2, near-infrared spectroscopy is used to measure the moisture content of Peppermint medicinal materials

[0108] (1) Medicinal material sample preparation: 30 batches of peppermint medicinal materials were selected, crushed and sieved, and set aside.

[0109] (2) Moisture determination (toluene method):

[0110] Take 4g of the test product, weigh it accurately, put it in a round bottom flask, add about 200ml of toluene, and if necessary, add a few pieces of dry and clean unglazed ceramic chips or glass beads, connect the instrument, and add from the top of the condenser tube. Add toluene to fill the narrow section of the tube. Put the round-bottomed flask in an electric heating mantle or heat it slowly by other suitable methods. When the toluene starts to boil, adjust the temperature so that 2 drops per second are distilled. When the water is completely distilled off, that is, when the water volume in the scale part of the measuring tube does not increase any...

Abstract

The invention relates to a near infrared spectrum detection method of mint medicinal materials. The near infrared spectrum detection method of the mint medicinal materials comprises the following steps that (1) the mint medicinal materials are smashed and sieved; (2) a near infrared spectrogram of mint medicinal material powder is collected; and (3) an established model is input according to a standard near infrared spectrogram and the collected near infrared spectrogram of the mint medicinal materials, the content of menthol in the mint medicinal materials is calculated and obtained, whereinthe spectrum conditions are that scanning times is 32, the resolution ratio is 8cm<-1>, the internal background of an instrument is used as reference, and a scanning spectral range is 4000-10000cm<-1>.

Description

technical field [0001] The invention belongs to the field of near-infrared detection, and in particular relates to a method for detecting the near-infrared spectrum of mint medicinal materials. Background technique [0002] Mint is the dry aerial part of Mentha haplocalyx Briq. It was first produced in the Mediterranean region of Europe and West Asia. At present, the main production areas are the United States, Spain, Italy, France, the United Kingdom, the Balkan Peninsula, etc., and most places in China such as Yunnan, Jiangsu, Zhejiang, Jiangxi, etc. are produced. It can be divided into five varieties: white mint, yellow mint, green mint, seedling mint and stinky mint. Su mint: Produced in Suzhou, Changshu, Jiading, Nantong and other places in Jiangsu. The quality is also excellent. Mint mint: produced in southern my country, such as Jiangxi, Jiangsu, Zhejiang, Anhui and other provinces. Hang mint: also known as amaranth bridge mint. Produced in Hangzhou, Zhejiang. ...
