Quality control of Sagina japonica by HPLC fingerprint combined with quantitative analysis of multi-components by single-marker
To establish the high-performance liquid chromatography (HPLC) fingerprint of
Sagina japonica
, and to establish a quantitative analysis of multi-components by single-marker (QAMS) method for simultaneous determination of six componen
ts in
S. japonica
,
aiming to provide references for the quality control of this medicinal herb.
METHODS
2
HPLC method was used to establish the fingerprints of 12 batches
(No. S1-S12) of
S
.
japonica
according to
Similarity Evaluation System of Chromatographic Fingerprint of Traditional Chinese Medicine
. The similarity evaluation and identification of common peaks were conducted, followed by cluster analysis (CA) and principal component analysis (PCA) for 12 batches of samples. Using vicenin-2 as internal reference, the contents of p-hydroxy cinnamic acid, apigenin-6-C-arabinoside-8-C-glucoside, isoorientin, vitexin and 20-hydroxyecdysone were determined by QAMS method. The results were then compared with those obtained by the external standard method.
RESULTS
2
The similarities of HPLC fingerprints for 12 batches of
S
.
japonica
ranged from 0.828-0.998. A total of 17 common peaks were calibrated, and 6 common peaks were identified. Specifically, peak 5 was identified as vicenin-2, peak 7 as p-hydroxycinnamic acid, peak 10 as apigenin-6-C-arabinoside-8-C-glucoside, peak 11 as isoorientin, peak 13 as vitexin, and peak 15 as 20-hydroxyecdysone. The results of CA showed that S1-S5, S7 and S9-S11 were clustered into one category, S6 was clustered into one category, and S8 and S12 were clustered into one category. The results of PCA revealed that the accumulative contribution rate of the four main components was 89.430%. The content ranges measured by QAMS method for p-hydroxy cinnamic acid, apigenin-6-C-arabinoside-8-C-glucoside, isoorientin, vitexin and 20-hydroxyecdysone were 0.017 4-0.269 4, 0.568 8-4.240 3, 0.503 2-5.040 3, 0.024 0-0.132 0 and 2.551 3-4.881 1 mg/g, respectively. There was no significant difference in the contents of components measured between QAMS method and the external standard method (
P
>0.05).
