Embodiment 1
[0114] Embodiment 1, the content of curcumadione, curcumol and gemmacone of curcuma medicinal material determined by near-infrared spectrometry
[0115] (1) Medicinal material sample preparation: select 30 batches of turmeric medicinal materials, crush and sieve, and set aside
[0116] (2) Content determination:
[0117] Take 6.0g turmeric fine powder, weigh it accurately, put it in a stoppered Erlenmeyer flask, add 20ml methanol accurately, weigh it, heat it under reflux for 30 minutes, let it cool, weigh it accurately, add methanol to make up for the lost weight, shake Evenly, let it stand, take the supernatant and filter it with a 0.45um microporous membrane. Liquid chromatography conditions: C-18 column (4.6*150mm, 5um), acetonitrile: 0.1% phosphoric acid aqueous solution (55:45) isocratic elution. Column temperature: 35°C, flow rate 1.0ml / min, detector DAD, detection wavelength 214nm, injection volume 5ul.
[0118] Through the above method, the three quality control inde...
Embodiment 2
[0132] Embodiment 2, near-infrared spectrometry measures the moisture content of curcuma medicinal material
[0133] (1) Medicinal material sample preparation: 30 batches of turmeric medicinal materials were selected, crushed and sieved, and set aside.
[0135] Take 10g 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. After the water is completely distilled off, that is, when the water volume in the scale part of the measuring tube does not increase any more, first...

Abstract
The invention discloses a near infrared spectroscopy detection method of a radix curcumae medicinal material. The method comprises near infrared detection of a water content, and/or, curdione, germacrone, and cincumol in radix curcumae. The method comprises the following steps: (1) preparation of a medicinal material sample, in which, a medicinal material is pulverized and sieved for later use; (2) target component detection, which comprises water content detection (through a methylbenzene method) or detection of curdione, germacrone, and cincumol (through a liquid phase method); (3) collection of near infrared spectroscopic data; (4) establishment of a quantitative model, in which, the near infrared spectroscopic data is associated with a known component content and the water content to establish the calibration quantitative model; and (5) near infrared detection of an unknown to-be-detected sample. The radix curcumae medicinal material can be quickly detected through the method; the method has advantages of simple operation and high accuracy; and the material is not wasted. Safe, efficient, controllable, and stable quality of the radix curcumae medicinal material is ensured.
Description
technical field [0001] The invention belongs to the field of near-infrared detection, and in particular relates to a near-infrared spectrum detection method for turmeric medicinal materials. Background technique [0002] Turmeric has the effects of promoting blood circulation and relieving pain, promoting qi and relieving stagnation, clearing heart and cooling blood, promoting gallbladder and reducing jaundice. There are three kinds of turmeric bases stipulated in the Chinese Pharmacopoeia, which are the dry tubers of CurcumawenyujinY.H.ChenetC.Ling, which is commonly called Wenyujin, mainly produced in Wenzhou, Zhejiang; Silk turmeric, mainly produced in Sichuan and Guangdong; Guangxi Curcumakwangsiensis S.G.LeeetC.F.Liang or the dry root of CurcumaphaeocaulisVal. . How to quickly distinguish the medicinal materials that meet the preparation requirements is the direction that needs to be discussed and studied today. [0003] Near-infrared (NIR) spectroscopy is a fast, no...
