Abstract
OBJECTIVE
To establish chromatographic fingerprint of Sichuan native medicinal plant Alisma plantago-aquatica by RP-HPLC for the quality control.
METHODS
The gradient elution mode was applied in chromatographic separation, and data were analyzed by "Computer Aided Similarity Evaluation" software to compare the quality of A. plantago-aquatica samples from different habitats.
RESULTS
The HPLC chromatographic fingerprinting of A. plantago-aquatica with 26 characteristic peaks was established from 17 lots of A. plantago-aquatica samples, peak 16 and 22 were identified as 24-acetyl alisol A and 23-acetyl alisol B, respectively.
CONCLUSIONS
The chromatographic fingerprinting of A. plantago-aquatica with high specificity can be used to control its quality and assure lot to lot consistency. The RP-HPLC fingerprint method is repeatable, feasible in analysis of A. plantago-aquatica.
