Embodiment 1
[0067] Such as figure 1 , 2 , One shown in 3, 4, 5, and 6 uses salvianolic acid B as a reference substance, and adopts thin-layer chromatography to identify whether Jieyu Shunxin tablets contain salvia miltiorrhiza; Laminar chromatography was used to identify whether Jieyu Shunxin Tablets contained Bupleurum components; the extract of Shichangpu reference medicinal material was used as the reference medicinal solution reference substance, and TLC was used to identify whether Jieyu Shunxin Tablets contained Shichangpu ingredients; TLC was used as the reference drug solution reference substance to identify whether Jieyu Shunxin Tablets contained polygala components; the turmeric control medicinal material extract was used as the reference drug solution reference substance to identify whether Jieyu Shunxin Tablets contained Polygala gold component; use berberine hydrochloride reference substance to identify whether there is Coptis chinensis in Jieyu Shunxin Tablets by thin-layer...
Embodiment 2
[0104] Take 5 tablets of Jieyu Shunxin Tablets, grind them finely, take about 0.5g, weigh them accurately, put them in a 50mL volumetric flask, add 20% ethanol, 40% ethanol, 60% ethanol, 80% ethanol, 100% ethanol, 20% ethanol Methanol, 40% methanol, 60% methanol, 80% methanol, and 100% methanol were each 50 mL, and the ultrasonic working frequency was 40KHz, and the power was 500W, and treated for 30 minutes. Take it out, let it cool, make up to volume with extraction solvent, shake well, and pass through 0.45μm Microporous membrane, filtration, sample injection analysis. see results Figure 7 .
[0105] The results showed that there were significant differences among the 10 extraction solvents, and the extraction rate of 80% methanol was higher, and the extraction with methanol was used as the test solution, the impurity peak was small, and the interference was small, so methanol was used as the extraction solvent of the test solution.
Embodiment 3
[0107] Take 5 pieces of Jieyu Shunxin Tablets, grind them finely, take about 0.5g, weigh them accurately, put them in a 50mL volumetric flask, add 50mL of 80% methanol accurately, and ultrasonically (working frequency 40KHz, power 500W) for 10min, 20min, 30min, respectively. After 40min, 50min, and 60min, take it out, let it cool, make up to volume with 80% methanol, shake well, pass through a 0.45μm microporous membrane, and inject the sample for analysis. see results Figure 8 .
[0108] The results showed that the extraction was basically complete in 40 minutes, so the extraction time was determined to be 40 minutes.
