Study on characteristic chromatogram of Chaenomeles sinensis and content determination of 3 flavones
, determine the contents of rutin, hyperin and quercitrin, and to identify
C. sinensis
and
C. speciosa
.
METHODS
2
HPLC method was performed on Agilent 5 TC-C
18
column, with acetonitrile-0.2% formic acid solution as the mobile phase for gradient elution, at the flow rate of 1.0 mL/min. The column temperature was 30 ℃. The detection wavelength was 330 nm in characteristic chromatogram and 350 nm in content determination. The characteristic chromatogram of
C. sinensis
was established and similarity was evaluated by the
Similarity Evaluation System for Chromatographic Fingerprint of TCM
(2012 edition). Hierarchical cluster analysis of 15 batches of
C. sinensis
(S1-S15) was performed by using SPSS 23.0 software. The contents of 3 flavones in 15 batches of
C. sinensis
and
7 batches of
C. speciosa
(S16-S22) were determined, while their characteristic chromatograms were compared.
RESULTS
2
The similarities of the characteristic chromatogram for 15 batches of
C. sinensis
ranged from 0.783 to 0.969, and 11 characteristic peaks were confirmed. Four constituents were identified as chlorogenic acid, rutin, hyperin and quercitrin. The medicinal materials in 15 batches of
C. sinensis
could be divided into 2 categories: S5-S8 were one category, and the others belonged to one category. The characteristic chromatogram of
C. sinensis
was obviously different from
C. speciosa
. The contents of rutin, hyperin and quercitrin in 15 batches of
C. sinensis
were 48.99-294.45, 3.49-102.55, 31.98-149.49 μg/g, respectively. The content of rutin in
C. speciosa
was lower than that in
C. sinensis.
None of hyperin (except for S20) and quercitrin were detected in
C. speciosa
.
CONCLUSIONS
2
The characteristic chromatogram and the method for content determination of 3 flavones in
C. sinensis
are established successfully and can be used for the quality control of
C. sinensis
and its identification from
C. speciosa
.
