Chromatogram comparing the fingerprints analyzed by chromatographic condition II (HPLC-ELSD) with negative control samples and reference standard samples: (a) S1–S8 were respectively the negative sample without Hirudo, without Curcumae Rhizoma, without Cervi Cornu Pantotrichum, without Fritillariae Thunbergii Bulbus, without Sparganii Rhizoma, without Astragali Radix, without Epimedii Folium, and without Ginseng Radix et Rhizoma, in which peaks 4 and 6 were from Astragali Radix; peaks 5 and 8 were from Ginseng Radix et Rhizoma by comparing with the negative control solutions (S1–S8); (b) S2 and S1 were respectively the fingerprints of the sample solution and reference standard solution, in which four peaks were respectively verified by comparing with the reference standard substance: peak 4, ginsenoside Rc; peak 5, astragaloside; peak 6, ginsenoside Rd; peak 8, astragaloside II.
