Figure 1. Typical HPLC fingerprint of YPFS at 210 nm.

Figure 1

Forty mg/mL YPFS was subjected to HPLC analysis, and the chemical fingerprint was revealed by a DAD detector. Prim-O-glucosylcimifugin (11), scopoletin (13), calycosin-7-O-β-D-glucoside (2), 5-O-methylvisammioside (12), ononin (4), calycosin (1) formononetin (3), atractylenolide III (10), atractylenolide I (8) and Atractylenolide II (9) were identified in the HPLC fingerprint of 210 nm. The chemical markers were numbered according to Fig. S1. Representative chromatograms are shown, n = 3.
