2 Figure 2. (A) The UV spectra of potocatechuic aldehyde (Pa), salvianolic acid A (Sa), salvianolic acid B (Sb), cryptotanshinone (Ct), tanshinone I (T1) and tanshinone IIA (T2) recorded between 190 and 400 nm. (B) Representative HPLC chromatograms of the six components in standard solution (a) and the sample solution: (b) S. miltiorrhiza “Aigan Broad leaf”, (c) S. miltiorrhiza “Anhui White leaf”, (d) S. miltiorrhiza “Gaogan Broad leaf”, (e) S. miltiorrhiza “Sibeiti Lobular leaf”, (f) S. miltiorrhiza “Zupei Broad leaf” and (g) S. miltiorrhiza “Zupei Lobular leaf”.
