Analysis on Chemical Constituents in Rhizomes of Bergenia scopulosa by UHPLC-Q Exactive Focus MS/MS增强出版
Ultra-high performance liquid chromatography coupled with quadrupole/electrostatic field orbital trap high resolution mass spectrometry (UHPLC-Q Exactive Focus MS/MS) was developed to rapidly analyze and identify the chemical components in the rhizomes of
Bergenia scopulosa
.
Method
2
The 75% methanol extract of
B
.
scopulosa
rhizomes was analyzed on a Thermo Accucore aQ RP18 column (2.1 mm×150 mm, 2.6 μm) with the mobile phase of methanol (A) and 0.1% formic acid aqueous solution (B) for gradient elution (0-40 min 5%-95%A, 40-45 min 95%A), the flow rate was 0.3 mL·min
-1
and the column temperature was at 30 ℃. The information of the chemical constituents was acquired in positive and negative ion modes by heated electrospray ion source (HESI), and the scanning range was
m
/
z
80-1 200.
Result
2
A total of 66 chemical constituents were identified, including 2 free amino acids, 7 bergenin derivatives, 15 flavonoids, 15 organic acids, 25 glycosides, and 2 others.
Conclusion
2
The chemical constituents in the rhizomes of
B
.
scopulosa
can be identified systematically, accurately and rapidly by this method. Among them, 8 compounds were unambiguously identified by comparing with reference substances (succinic acid, arbutin, gallic acid, protocatechuic acid, bengenin, catechin, chlorogenic acid and caffeic acid), 51 compounds were found from
B
.
scopulosa
for the first time and 28 compounds were found from the genus
Bergenia
for the first time. This paper can provide an important basis for the further material basis clarification and quality assessment of
