A high-performance liquid chromatographic method with evaporative light scattering detection (HPLC-ELSD) has been developed to identify and quantify 19 ginsenosides (Rg(1), Re, Rf, Rb-1, Rc, Rb-2, Rd, F-4, Rg(6), Rk(3), Rh-4, 20(S)-, 20(R)-Rg(3), 20(S)-. 20(R)-Rs(3), Rk(1), Rg(5), Rs(4), and Rs(5)) in black ginseng (BG, Korean white ginseng that was subjected to nine cycles of steam treatment). Ultrasonication is employed for sample preparation, and the analysis is achieved on a Discovery C-18 column using gradient elution of CH3CN-H2O-CH3COOH without buffer in 40 min. The method was validated by linearity (r(2) >= 0.9994), precision (92.0-107.5%), intra- and inter-day accuracy (R.S.D. < 3.21%), and limit of detection (LOD
