Embodiment 1
[0023] Use the present invention to measure the raspberry glycoside content in cigarette paper A, the steps are as follows:
[0024] ①Sample extraction: Accurately weigh 0.1000g of shredded cigarette paper A into a plastic centrifuge tube, add 20mL of pure water, and conduct ultrasonic extraction for 30 minutes; after centrifugation, transfer the supernatant to a 50mL volumetric flask; extract the residue once more, and centrifuge Finally, transfer the supernatant to a 50mL volumetric flask; make up to volume with pure water, shake well, and filter with a 0.22μm nylon filter membrane to obtain a test sample.
[0025] ② Determination: Analysis is carried out by high performance liquid chromatography, and the instrument conditions are as follows:
[0026] The conditions of liquid chromatography are: chromatographic column: C18 column, specifications: 3μm, 4.6mm×150mm; flow rate: 1.0mL / min; column temperature: 25~35℃; injection volume: 10μL; Phase B is 0.1wt% formic acid aqueous...
Embodiment 2
[0029] Use the present invention to measure the content of raspberry in cigarette paper B, the steps are as follows:
[0030] ①Sample extraction: Accurately weigh 0.1000g of shredded cigarette paper B into a plastic centrifuge tube, add 20mL of pure water, and conduct ultrasonic extraction for 30 minutes; after centrifugation, transfer the supernatant to a 50mL volumetric flask; extract the residue once more, and centrifuge Finally, transfer the supernatant to a 50mL volumetric flask; make up to volume with pure water, shake well, and filter with a 0.22μm nylon filter membrane to obtain a test sample.
[0031] 2. measure: adopt high-performance liquid chromatography to analyze, and instrument condition is the same as embodiment 1.
[0032] The preparation of the standard solution is the same as in Example 1. The standard curve equation Y=1.82477X+4.50945 and the correlation coefficient R2=0.99993 were obtained according to the concentration and peak area of raspberry glucos...
Embodiment 3
[0034] Use the present invention to measure the purity of the raspberry glycoside sample, the steps are as follows:
[0035] ①Preparation of sample solution: Accurately weigh 5.0mg of the sample and dissolve it in a 10mL volumetric flask, dissolve it in pure water to a constant volume, and filter it with a 0.22μm nylon membrane to obtain the test sample;
[0036] 2. measure: adopt high-performance liquid chromatography to analyze, and instrument condition is the same as embodiment 1.
[0037] According to the area normalization method, the purity of the obtained raspberry glucoside was 99.1%.
