Difference Analysis of Chemical Constituents in Different Varieties of Puerariae Flos by UPLC-Q-TOF-MS
To compare the chemical constituents of Puerariae Flos from three different varieties of
Pueraria montana
var.
lobata
,
P. montana
var.
thomsonii
and
P
.
montana
var
. montana
.
Method
2
Ultra-performance liquid chromatography-quadrupole-time-of-flight mass spectrometry (UPLC-Q-TOF-MS) was used with the mobile phase of 0.1% formic acid aqueous solution (A)-acetonitrile (B) for gradient elution (0-20 min, 10%-30%B; 20-30 min, 30%-55%B; 30-35 min, 55%-95%B; 35-37 min, 95%B; 37-40 min, 95%-10%B), the flow rate was 0.25 mL·min
-1
. Electrospray ionization (ESI) was used to scan and collect MS data in positive and negative ion modes with scanning range of
m
/
z
50-1 500. The chemical components from different sources of Puerariae Flos were identified in combination with the chemical composition database and literature information. After the obtained data were normalized by MarkerView
TM
1.2.1, they were imported into SICMA-P 14.1 software for principal component analysis (PCA) and orthogonal partial least squares discriminant analysis (OPLS-DA) to select the main differentiated components among the three different varieties.
Result
2
A total of 35 compounds were identified from three different varieties of Puerariae Flos, including 22 isoflavones, 6 flavonoids and 7 saponins. The flowers of
P
.
lobata
,
P. montana
var.
thomsonii
and
P
.
montana
var
. montana
contained 32, 35, 33 compounds, respectively. And 18 differential compounds were screened under the positive and negative ion modes, including kakkalide, tectoridin, 6″-
This research is the first to systematically study the chemical constituents of the flower of
P
.
montana
var
. montana
, although the flower of
P
.
montana
var
. montana
is used as adulterants, it has high contents of tectoridin and 6″-
O
-xylosyl-tectoridin, which has great potential for development. The efficacy components such as kakkalide and tectoridin in Puerariae Flos from the three sources of varieties are obviously different, and it is necessary to carefully consider the application of these three varieties as Puerariae Flos.
