Embodiment 1

[0020] 1. Drying and sifting: take the medicinal material (sample A) of tangerine peel to be identified, break the whole tangerine peel sample into small pieces and put it into a tangerine peel grinder for crushing, grind the crushed sample and pass it through a 300-mesh sieve. The 300-mesh tangerine peel sample was placed in a weighing bottle and dried in a drying oven at a temperature of 60 °C to constant weight.

[0021] 2. Tablet compression: Mix the original medicinal material sample of tangerine peel after constant weight with KBr crushed crystals in a ratio of 1:100, grind until the fine powder is uniform, and then compress into tablets.

[0022] 3. Tablet samples were scanned in the infrared spectrum in the range of 4000 - 400 cm-1 ( Figure 6 ), and compared the spectra to the library, the ratio of the intensity of the 1742 cm-1 absorption peak to the intensity of the base peak at 1635 cm-1 was 0.38, which was greater than 0.20.

Embodiment 2

[0026] 1. Drying and sifting: Take the medicinal material (sample B) of tangerine peel to be identified, break the whole tangerine peel sample into small pieces and put it into a tangerine peel grinder for crushing, grind the crushed sample and pass it through a 200-mesh sieve. Put the 200-mesh tangerine peel sample in a weighing bottle and dry it in a normal temperature vacuum oven (vacuum degree less than 0.1 MPa) to constant weight.

[0027] 2. Tablet compression: Mix the original medicinal material sample of tangerine peel after constant weight with KBr crushed crystals in a ratio of 1:100, grind until the fine powder is uniform, and then compress into tablets.

[0028] 3. Tablet samples were scanned in the infrared spectrum in the range of 4000 - 400 cm-1 ( Figure 7 ), and compared the spectra to the library, the ratio of the intensity of the 1742 cm-1 absorption peak to the intensity of the 1635 cm-1 base peak was 0.15, which was less than 0.20.

Abstract

The invention discloses a simple method for identifying different ageing years of dried tangerine or orange peel and citrus chachiensis hortorum medicinal materials by virtue of infrared spectroscopy.The method comprises the following steps: 1) selecting dried tangerine or orange peel and citrus chachiensis hortorum medicinal materials, smashing, and sieving; 2) acquiring infrared spectroscopy (4000-400cm<-1>) of a sample and gas chromatography-mass spectrometry data of corresponding volatile oil; 3) discriminating and analyzing years of the dried tangerine or orange peel and citrus chachiensis hortorum according to characteristic peaks of the infrared spectroscopy; 4) analyzing variation of an infrared characteristic peak by combining a gas chromatography-mass spectrometry qualitative result; and 5) with 1635cm<-1> absorption peak as a base peak, judging the year of the dried tangerine or orange peel according to a strength ratio of 1742cm<-1> absorption peak to 1635cm<-1> absorptionpeak. The invention establishes an accurate, rapid, lossless and pollution-free traditional Chinese medicinal material analysis method, the traditional Chinese medicinal material dried tangerine or orange peel on the market can be rapidly analyzed, the years of the dried tangerine or orange peel and citrus chachiensis hortorum can be judged, and an identification reference base is provided for related adulterate and shoddy dried tangerine or orange peel products.

Description

technical field [0001] The invention relates to a rapid detection technology of medicinal materials, in particular to an infrared spectrum year identification method for the quality of dried tangerine peel and tangerine peel medicinal materials. Background technique [0002] Chenpi is derived from Rutaceae plant Tangerine ( Citrus reticulata Blanco) and its cultivars contain a large number of active medicinal ingredients, including volatile oils, flavonoids, polysaccharides, etc., which have the functions of regulating qi, invigorating the spleen, drying dampness and resolving phlegm. The 2010 edition of the Chinese Pharmacopoeia records that the medicinal materials of tangerine peel can be divided into tangerine peel and tangerine peel. The tangerine peel comes from a variety of citrus plants such as Fuju, Dahongpao, and Wenzhou tangerine. The tangerine peel is produced in Guangdong Province, which is different from other provinces. Guang tangerine peel is produced in Gua...
