Embodiment 1
[0066] The sanshool assay method in rattan pepper that the embodiment of the present invention provides is as follows: figure 1 As shown, as a preferred embodiment, such as image 3 As shown, the method for preparing different concentrations of samples to be tested by using the sample preparation module to be tested provided by the embodiment of the present invention using the sample preparation program to be tested includes:
[0067] S201, after destemming the rattan pepper sample, mix it evenly, weigh 5g of the sample into a 50mL centrifuge tube, add about 20mL of acetonitrile, homogenize with a homogenizer, and then ultrasonically extract for 20min;
[0068] S202, after centrifuging at 5000r / min for 5min, take out the supernatant, continue to add 20mL of acetonitrile to the residue, repeat the above extraction steps, combine the two extracts into a 50mL volumetric flask, dilute to the mark with acetonitrile, and shake well;
[0069] S203: Precisely pipette 1 mL of the extr...
Embodiment 2
[0071] The sanshool assay method in rattan pepper that the embodiment of the present invention provides is as follows: figure 1 As shown, as a preferred embodiment, such as Figure 4 Shown, the method that carries out the drawing of standard curve according to sanshool standard working solution by curve drawing program that the embodiment of the present invention provides comprises:
[0072] S301, take an appropriate amount of sanshool, weigh them accurately, place them separately in 5mL brown volumetric flasks, add methanol to dissolve and dilute to the mark, shake well, and prepare control stock solutions with different mass concentrations;
[0073] S302, draw an appropriate amount of stock solution, put it in a 10mL volumetric flask, dilute to the mark with methanol, and shake well to obtain the mixed standard working solution of hydroxy-α-sanshool, hydroxy-β-sanshool and hydroxy-γ-sanshool ;
[0074] S303: Precisely draw an appropriate amount of mixed standard working so...
Embodiment 3
[0077] The sanshool assay method in rattan pepper that the embodiment of the present invention provides specifically comprises:
[0078] (1) Standard preparation module
[0079] Accurately weigh an appropriate amount of hydroxy-α-sanshool, hydroxy-β-sanshool, and hydroxy-γ-sanshool in a 5mL brown volumetric flask, dissolve with methanol and set the volume to the mark, and shake well to obtain hydroxy-α-sanshool , hydroxy-β-sanshool and hydroxy-γ-sanshool stock solutions. Take an appropriate amount of the stock solution, put it in a 10mL volumetric flask, dilute to the mark with methanol, and shake well to obtain the mixed standard working solution of hydroxy-α-sanshool, hydroxy-β-sanshool and hydroxy-γ-sanshool.
[0080] (2) standard curve concentration determination module
[0081] Accurately draw a proper amount of the above-mentioned standard working solution, and prepare a series of standard solutions of 1-500 μg / mL with methanol (prepared and used now). - sanshool, hyd...
