| titleOfInvention | Standard fingerprint spectrum construction method of Yitong tablet and method for measuring its component content |
| abstract | The invention relates to a construction method of standard fingerprint of a yitong tablet and a method for measuring the component content of the yitong tablet, which comprises the following steps: preparing a test solution; preparation of control solutions: dissolving barbaloin in mixed solution of methanol and 0.1% volume concentration acetic acid water, respectively dissolving naringin, neohesperidin and echinacoside in methanol to obtain reference solutions; and (3) high performance liquid chromatography detection: the chromatographic conditions are as follows: adopting a mobile phase A as methanol and a mobile phase B as 0.1% volume concentration acetic acid aqueous solution, wherein the total flow rate is 1 ml/min; performing gradient elution; establishing standard fingerprint of the yitong tablet; the fingerprint spectrum of the invention has better peak type, better separation degree, symmetrical factor and theoretical plate number; the method can effectively separate the components with smaller structural difference, can better improve the quality of standard products, and can more accurately realize the simultaneous determination of the content of the effective components in the products. |
