Embodiment 1

[0022] Method and Results

[0023] Preparation of sample and reference solution

[0024] Preparation of the test solution

[0025] Precisely draw 0.4mL of ginger juice, put it in a 25mL measuring bottle, add absolute ethanol to dissolve and set the volume to the mark, shake well, and filter to get ready.

[0026] Preparation of reference solution

[0027] Accurately weigh 5.20mg of 6-gingerol into a 25mL measuring bottle, add absolute ethanol to dissolve and make the volume up to the mark, shake well, then precisely draw 2mL into a 10mL measuring bottle, add absolute ethanol to make up to the mark, Shake well and serve.

[0028] Selection of measurement wavelength: Scan the 6-gingerol reference solution and ginger juice test solution at 200-400nm wavelength respectively, and the result is that both have maximum absorption at 281nm.

Embodiment 2

[0029] Embodiment 2 linear relationship investigation

[0030] Accurately weigh an appropriate amount of 6-gingerol reference substance, add methanol to prepare 1.226mg·mL -l Precisely draw 1, 5, 10, 15, 18, and 20 μL of the solution, respectively, and inject samples sequentially for detection. The detection conditions are chromatographic column: Phenomenex Gemini C18 (4.6mm×250mm, 5um); flow rate: 1.0mL / min; column Temperature: 25°C; mobile phase selection: acetonitrile: methanol: water (43:5:52); measurement wavelength: 280nm. Injection volume of reference substance (mg·mL -l ) is the abscissa, and the integral value of the peak area is the ordinate, draw a standard curve and regression processing, the results show that 6-gingerol is 1.226~24.52mg·mL -l The range has a good linear relationship, and the regression equation is y=578.88x+91.297, r ＝ = 0.9999. See figure 1 Standard Curve Chart. The content determination of 6-gingerol in the ginger juice of embodiment 3

Abstract

The invention provides a method for determining 6-gingerol content in a processing adjuvant ginger juice. According to the invention, methanol is taken as an extract, a sample is prepared through two-time ultrasonic treatment, and is detected through high performance liquid chromatography, and the 6-gingerol content in the ginger juice can be calculated according to a regression equation being y=578.88x+91.297 and r=0.9999. The sample processing method is simple, the 6-gingerol content in a sample solution is stabilized in at least 24 hours, method reappearance is good, precision is high, andthe method is suitable for large-area popularization.

Description

technical field [0001] The invention belongs to the technical field of detection of traditional Chinese medicine components, and in particular relates to a method for determining the content of 6-gingerol in ginger juice, a processed auxiliary material. Background technique [0002] Ginger is the fresh rhizome of ginger (Zingiber officinale Roscoe), a perennial herb of the Zingiberaceae family. The rhizome is irregular and massive, with a yellowish-brown or gray-brown surface. Traditional Chinese medicine believes that the skin of ginger is pungent and cool, which can cure skin edema and promote skin water; ginger juice is pungent and warm, and has a strong power to dispel stomach cold, and is mostly used for vomiting; Big, Pao Jiang tastes hard and goes inside but not outside, warming the coldness of the scorcher; Ginger is pungent and dissipates temperature, benefits the spleen and stomach, is good at warming the middle and reducing adverse reactions to stop vomiting, deh...
