Approach Based on PMP-HPLC Fingerprint and Chemometrics to Compare Difference of Polysaccharide in Polygonati Rhizoma
To established an approach of chemical fingerprinting and study the differences of the polysaccharides from three species of Polygonati Rhizoma in
Chinese Pharmacopoeia
so as to provide reference for quality evaluation and clinical application of Polygonati Rhizoma.
Method:
2
The polysaccharides were extracted by water extraction and alcohol precipitation from Polygonati Rhizoma. After hydrolysis by trifluoroacetic acid (TFA) and pre-column derivation by PMP
the chromatographic fingerprints of three kinds of Polygonati Rhizoma were established by high performance liquid chromatography. The fingerprinting model and chemometrics method
include similarity analysis (SA)
cluster analysis (HCA) and principal component analysis (PCA) were used for compare the differences among three species.
Result:
2
There were some differences in the PMP-HPLC fingerprints and monosaccharide composition from the three species. The
D
-mannose
L
-rhamnose and
L
-fucose were not detected
but they all contained
D
-galacturonic acid
D
-glucosamine hydrochloride
D
-galactose
D
-glucose and
D
-xylose among three species. The PCA and HCA analysis showed that chromatographic fingerprints of
P
.
cyrtonema
and
P
.
sibiricum
were similar
while
P
.
kingianum
and other two species were significantly different.
Conclusion:
2
There are differences in fingerprints of polysaccharides among three species of Polygonati Rhizoma. The possible effects of species should be considered in clinical application. The established PMP-HPLC is a simple
accurate and reproducible method
which can be used for the quality evaluation of Polygonati Rhizoma.
