Quantitative and Fingerprint of Ilex pubescens Slices
and simultaneously determine two components in 46 batches of
I
.
pubescens
in pieces of
I
.
pubescens
saponin A
1
and B
1
in order to provide a reference for the quality standard of
I
.
pubescens
slices.
Method:
2
Methanol was used to extract the
I
.
pubescens
saponin samples
and the extracts were measured by HPLC-UV with the absorption wavelength at 210 nm. Kromasil C
18
column (4.6 mm×250 mm
5 μm) was used for determining the extracts at a flow rate of 1.0 mL·min
-1
. The mobile phase condition was acetonitrile-0.1%phosphoric acid aqueous solution with gradient mode. The chromatographic fingerprint similarity evaluation system of traditional Chinese medicine (2012 edition) was used to analyze
I
.
pubescens
fingerprints. SPSS 20.0 software was used to cluster the peak area of common peaks. Principal component analysis was performed to reduce the dimension of common peaks.
Result:
2
There were great differences between the root and stem parts in
I
.
pubescens
fingerprints. The fingerprints of roots and stems of
I
.
pubescens
were established respectively
cluster results assorted the roots of
I
.
pubescens
into three categories andthe branches of
I
.
pubescens
into two categories. The integrity and difference of
I
.
pubescens
decoction pieces from different parts and places of origin were compared
and the principal component analysis was performed to screen out the common components that played a decisive role in fingerprint of
I
.
pubescens
pieces. And the common peaks were determined. The content of saponin A
1
and saponin B
1
in Radix
I
.
pubescens
were determined.
Conclusion:
2
The established
I
.
pubescens
fingerprints and content determination methods are simple and suitable. Cluster analysis and principal component analysis are used to screen out the key components of quality control of
I
.
pubescens
. The results can provide references for quality control of
