| titleOfInvention | The construction method of contracting spring standard preparation finger-print and characteristic spectrum and quality determining method |
| abstract | The invention discloses a kind of finger-print and characteristic spectrum detection method of contracting spring preparation, comprise the mensuration of the preparation of reference substance solution, the preparation of need testing solution, the correlativity between each bulk drug and finished product; Adopt multi-wavelength handoff technique to measure, with the chromatographic peak retention time of reference substance and peak area for 1, calculate test sample relative retention time and relative peak area, namely obtain contracting spring preparation HPLC standard finger-print.The finger-print that the contracting spring preparation HPLC standard finger-print that method obtains thus belongs to Chinese yam has 5 total peaks; The finger-print belonging to fructus alpiniae oxyphyllae has 4 total peaks; The finger-print belonging to the root of three-nerved spicebush has 9 total peaks.The inventive method adopts the detection method of multi-wavelength can reach the object increasing quality coverage rate, improve detection sensitivity and Detection job, energy quality that is comprehensive, objective, scientifically evaluation contracting spring preparation, particularly can it can be used as one of index of contracting spring preparation True-false distinguish. |
