ABSTRACT
Objective:
To establish a rational method for Laportea bulbifera quality control.Methods:
The fingerprint technique and multi-component quantitation were used to study the quality control of L. bulbifera by UHPLC. The 12 batches of L. bulbifera UHPLC fingerprint were evaluated by the evaluation system on similitude degree of chromatogram fingerprint of traditional Chinese medicine.Results:
The quality control methods of Miao medicine L. bulbifera for simultaneous determination of 10 components (including neochlorogenic acid, cryptochlorogenic acid, chlorogenic acid, rutin, isoquercitrin, luteoloside, kaempferol-3-O-rutinoside, quercitrin, epigallocatechin and epicatechin) were established. The linear, precision, repeatability and stability are good. The standard recoveries were 95.89%-98.62%, with RSD less than 3%. The common mode of fingerprint was established after determination fingerprints of 12 batches of samples of L. bulbifera by UHPLC. There were 20 common peaks in these samples. The similarity of the 12 batches fingerprints were in the range from 0.805 to 0.931.Conclusion:
The fingerprinting and multi-index content determination methods for quantitative control of Miao medicine L. bulbifera have high sensitivity, good accuracy, stability and reliability, which can provide a theoretical and experimental foundation for quantitative control of Miao medicine L. bulbifera.
