Fingerprint of Epimedium wushanense Based on Principal Component,Factor and Cluster Analysis
so as to provide theoretical basis for its quality evaluation.
Method:
2
The chromatographic column was Agilent infinitylab poroshell 120 SB-C
18
(3.0 mm× 100 mm
2.7 μm)
the flow phase was acetonitrile (A)-water (B) with a gradient of 0-5 min
25%-26%A; 5-6 min
26%-34%A; 6-11 min
34%-38.5%A; 11-17 min
38.5%-100%A; 17-20 min
100%A
the flow rate was 0.8 mL·min
- 1
the detection wavelength was 270 nm
and the column temperature was 30 ℃.
Result:
2
The cluster analysis better classified
E
.
wushanense
from different producing areas.
E
.
wushanense
from Guizhou province and
E
.
wushanense
from Chongqing were classified as class Ⅱ.
E
.
wushanense
from Guizhou province and Chongqing were far apart
indicating that the quality of
E
.
wushanense
varies from place to place affected by environment and climate. The results of principal component analysis showed that the quality of
E
.
wushanense
produced in Chongqing was better than that of
E
.
wushanense
produced in Guizhou. Among them
CQWS-02 (Yaque village
Guanyang town
Wushan county
Chongqing) and CQWS-10 (Hewan
Guanyang town
Wushan county
Chongqing) can be considered in the selection of high-quality varieties. In addition
No.1 common peak (epimedin A)
No.2 common peak (epimedin B)
No.4 common peak (icariin) and No.5 common peak (unknown component) in the fingerprint of the test samples could be used as the evaluation index components of
E
.
wushanense
quality.
Conclusion:
2
Principal components
factors and cluster analysis are used to achieve the rapid analysis
and their respective advantages are brought into full play for mutual verification and supplement. And the quality of
E
.
wushanense
in different origins can be comprehensively evaluated in all-round ways.
