Objective: To establish UPLC method for the determination of main flavone in Astragalus membranaceus peparation. Method: ACQUITY UPLCTMBEH C18column(2.1 mm×50 mm
1.7 μm) was used with Methanol-0.2% formic acid Wateras a mobile phase. The flow rate was 0.5 mL·min-1
The detecting wavelength was set at 200-400 nm.The column temperature was at 30℃. Result: The linear ranges of calycosin glycoside
formononetin glycoside
calycosin and formononetin were 0.1313-1.313 g·L-1(r=0.9997)
0.1186-1.186 g·L-1(r=0.9994)
0.020 6-0.206 g·L-1(r=0.9995)
0.0150-0.150 g·L-1(r=0.9995). The average recoveries were 97.07%
97.26%
97.45%
96.97%. Conclusion: The method was reliable
accurate and quickly. It can be used for quality control of A. membranaceus peparation.
