HPLC Fingerprint Analysis and Chemistry Pattern Recognition of Wild and Cultivated Notholirion bulbuliferum from Different Regions
To establish the HPLC fingerprint of wild and cultivated
Notholirion bulbuliferum
and recognize them according to the chemical pattern
in the expectation of providing the basis for the quality control and domestication cultivation of
N
.
bulbuliferum
of origins.
Method:
2
Twenty samples of wild and cultivated
N
.
bulbuliferum
collected from different origins were detected by HPLC
and a common mode of fingerprint was established. The Similarity Evaluation System for Chromatographic Fingerprint of TCM (2012A edition) was used to evaluate the similarity of the samples. The differences among the samples were identified by chemical pattern recognition methods
including principal component analysis (PCA)
cluster analysis (HCA) and partial least squares discriminate analysis (PLS-DA).
Result:
2
The HPLC fingerprint of
N
.
bulbuliferum
was obtained
and 26 common peaks were found in the chromatograph. Similarities of all samples were over 0.9
PCA
and HCA and PLS-DA results demonstrated obvious distinctions between wild and cultivated
N
.
bulbuliferum
. Eight constituents
such as pcoumaric acid were identified as biomarkers
representing major differences between the two varieties.
Conclusion:
2
The HPLC chromatogram of
N
.
bulbuliferum
developed in this paper has strong characteristics and repeatability. After being combined with the pattern recognition mode
it can be used as an effective method for evaluating the quality of
N
.
bulbuliferum
and distinguishing wild and cultivated
N
.
bulbuliferum
and provide a reference for the quality control and domestication introduction of
