Chromatographic fingerprint of Cistanche deserticola by HPLC / 中草药

ABSTRACT

Objective To establish chromatographic fingerprint of Cistanche deserticola by HPLC and evaluate the difference of inner qualities of samples from different habitats.Methods HPLC gradient elution was applied to establish the chromatographic fingerprint and "Computer Aimed Similarity Evaluation System" was used in data analysis.Results This chromatographic fingerprint method has good precision, stability, and repeatability; the fingerprints of the samples from different habitats were quite different.Conclusion There are notable differences in inner qualities of the samples from different habitats.This chromatographic fingerprint method can be used to evaluate the quality of C.deserticola.
