Embodiment 1
[0020] A preparation method of compound black tartary buckwheat tea.
[0021] The preparation method of described compound tea comprises the following steps:
[0022] Step 1: Wash the red dates, remove the core, and dry;
[0023] Step 2: Take black tartary buckwheat rice, rhodiola root tubers, and pagoda japonica rice, screen, wash, and dry;
[0024] Step 3: Pulverize the dried black tartary buckwheat rice, rhodiola rosea root, pagoda tree, and red dates respectively, and pass through a 50-mesh sieve;
[0025] Step 4: Take 5 parts of black tartary buckwheat powder, 3 parts of rhodiola rosea powder, 1 part of pagoda seed powder, and 1 part of red date powder, mix well; add appropriate amount of warm water to prepare soft material, pass through a 20-mesh sieve, extrude and granulate;
[0026] Step 5: Put the above-mentioned granules in an oven, bake them at 105°C for 3 hours until they are completely dry, take them out, let them cool, and pack them to obtain the compound black...

[0028] Determination of Rutin Content in Compound Black Tartary Buckwheat Tea
[0029] Chromatographic conditions: chromatographic column: C18 chromatographic column; mobile phase: methanol: 0.1% phosphoric acid water, gradient elution, the ratio change is shown in Table 1; detection wavelength: 256nm; flow rate: 1mL / min; column temperature: 30°C; injection volume : 10 μL.
[0030] Standard curve: Accurately weigh an appropriate amount of rutin standard substance and prepare 1000μg / mL, 500μg / mL, 300μg / mL, 150μg / mL, 50μg / mL, 20μg / mL standard solutions with chromatographic methanol, and inject and measure according to the above chromatographic conditions Its peak area, with sample concentration as abscissa, peak area as ordinate, the calibration curve equation that obtains is: y=11510x+187583 (R 2 = 0.9963).
[0031] Need testing solution: get 2g of compound black tartary buckwheat tea in example 1, place in 250mL round bottom flask, add 50mL80% analytical methanol, reflux ext...

[0037] Content detection of salidroside in compound black tartary buckwheat tea
[0038] Chromatographic conditions: chromatographic column: C18 chromatographic column; mobile phase: methanol: 0.1% phosphoric acid water, gradient change as shown in Table 1; detection wavelength: 275nm; flow rate: 1mL / min; column temperature: 30°C; injection volume: 10μL.
[0039] Standard curve: Accurately weigh an appropriate amount of salidroside standard substance and use chromatographic methanol to prepare standard solutions of 500μg / mL, 250μg / mL, 150μg / mL, 75μg / mL, 25μg / mL, and 10μg / mL. Sample measures its peak area, is abscissa with sample concentration, and peak area is ordinate, and the standard curve equation that obtains is: y=1566.6x+7618.9 (R 2 =0.9955)
[0040] Need testing solution: get 2g of compound black tartary buckwheat tea in example 1, place in a round-bottomed flask, add 50mL80% analytical methanol, reflux extraction at 70°C for two hours, filter, repeat the above operat...
