- W3046367076 abstract "This work describes the holistic fingerprinting method based on liquid chromatography coupled with charged aerosol detection(CAD) to profile non-saponin from water-soluble parts and determination of dencichine in Panax ginseng(PG), P. quinquefolium(PQ) and P. notoginseng(PNG). Sample extraction was carried out by water with ultra sonication for 30 min, which was eluted by Retain PEP for further analysis. The analysis was performed on a Hypercarb of porous graphitized carbon(3.0 mm×150 mm, 3 μm) column with acetonitrile and 0.1% perfluoropentanoic acid as mobile phase at a flow rate of 0.8 mL·min~(-1). Temperature of evaporator and nitrogen pressure for CAD were set at 50 ℃and 60.1 psi(1 psi≈6.895 kPa), respectively. As a result, dencichine and other polar components had a good performance on resolution and retention. The correlation coefficient(R~2) of dencichine was 0.998 2 in the concentration from 0.019 2 to 0.48 μg·mL~(-1). Limit of quantitation calculated by signal to noise of 10 was 7.4 ng·mL~(-1), and the recovery ranged from 95.52% to 102.7%. Chemical profile of the water-soluble part from PG, PQ and PNG was similar holistically, while the relative content for dencichine and other partial components varied significantly. The proposed method was used for characteristic of chemical profiling for non-saponin from water-soluble part, and determination of dencichine in PG, PQ and PNG." @default.
