Objective:
2
To establish a high performance liquid chromatography (HPLC) method for determination of four active constituents
namely MSTG-A
MSTG-B

var.
yunnanensis
in order to provide a methodological basis for the in-depth study and quality control of
G
.
leucocarpa
var.
yunnanensis
and lay a foundation for later preparation and clinical application.
Method:
2
The determination was performed on COSMOSIL 5C
18
-PAQ (4.6 mm×250 mm
5 μm) column with methanol-0.2%glacial acetic acid (gradient elution) as the mobile phase at a flow rate of 1 mL·min

. The column temperature was 25 ℃. The detection wavelength was set at 294 nm.
Result:
2
The linear range of MSTG-B
MSTG-A
gaultherin and chlorogenic acid were 0.014 06-0.450 00
0.007 81-0.250 00
0.003 13-0.100 00
0.000 94-0.030 00 g·L

respectively
with a good precision
repeatability and stability. And the average recoveries were 100.81%
98.99%
96.12%and 102.56%
respectively. RSDs were 1.4%
0.7%
0.7%
2.4%
respectively. The contents of MSTG-B
MSTG-A
gaultherin and chlorogenic acid in ARF fraction of

respectively.
Conclusion:
2
The established method was simple and accurate
with a high repeatability. It can be used for determination of four active constituents in ARF fraction of
G
.
leucocarpa
var.
yunnanensis
so as to provide a reference for the in-depth research
quality control and comprehensive evaluation of
G
.
leucocarpa
