Chemical fingerprint of (a) standards used: (1) internal standard : gallic acid, (2) caffeic acid, (3) p-coumaric acid, (4) 3,4-dicaffeoylquinic acid, (5) 3,5-dicaffeoylquinic acid, (6) 4,5-dicaffeoylquinic acid, (7) cinnamic acid, (8) aromadendrin, (9) isosakuranetin, and (10) Artepillin C, and of the extracts evaluated, PEE (b), PMM (c), and PSDE (d) (n = 3). The chromatograms were plotted at 275 nm, using the RP-HPLC, C18 (Shim-pack, CLC-ODS (M), 25 cm × 4.6) column, and gradient elution with methanol and acidic water (formic acid pH = 2.7).
