| titleOfInvention | UPLC fingerprint spectrum detection method of xuefu zhuyu decoction and capsules |
| abstract | The invention discloses a UPLC fingerprint spectrum detection method of xuefu zhuyu decoction and capsules, and belongs to the field of column chromatography. According to the detection method, ultra-high performance liquid chromatography analysis is conducted on contents of xuefu zhuyu powder or capsules and a reference substance solution. Chromatographic conditions are that gradient elution is conducted by taking acetonitrile as a mobile phase A and taking a 0.1% formic acid aqueous solution as a mobile phase B, the detection wavelength is 280 nm, the column temperature ranges from 30 DEG C to 50 DEG C, the flow velocity ranges from 0.3 mL.min＜-1＞ to 0.5 mL.min＜-1＞, and the injection volume is 2 microlitres. Fingerprint spectrum information of the xuefu zhuyu decoction and capsules is analyzed, 30 common peaks are totally obtained, the relative retention time and relative peak area of the common peaks are calculated by taking rhoifolin as a reference peak, and 16 common peaks are identified through a standard substance comparison method. The UPLC fingerprint spectrum detection method of the xuefu zhuyu decoction and capsules is comprehensive, rapid and reliable, fingerprint spectrum information of multiple components can be comprehensively obtained by means of the method, and therefore a reference basis is provided for quality control of the xuefu zhuyu decoction and capsules. |
