| titleOfInvention | The detection method of carminic acid content in a kind of gelatine capsule |
| abstract | The present invention relates to detection technique field, in particular to the detection method of carminic acid content in a kind of gelatine capsule.The detection method includes: gelatine capsule shell sample to be added in the hydrochloric acid solution of sulfur acid sodium, trisodium citrate and zinc acetate, keeps the temperature under the conditions of 60~80 DEG C, dissolves sample, obtain sample solution；Sample solution is mixed with dehydrated alcohol, is centrifuged, gained supernatant is adjusted into pH value to 5~7, is diluted, filtering, gained filtrate is test sample liquid；Test sample liquid, carminic acid standard solution are detected using high-efficient liquid phase chromatogram technology, utilize the content of carminic acid in external standard method gelatine capsule shell sample.Detection method can realize the accurate detection of carminic acid content, and linear relationship, precision, have good stability, and noiseless, detection limit, quantitative limit are low, and the rate of recovery is high. |
