HPTLC analysis results indicating the main secondary metabolites contained by Hypericum capitatum extracts (each lane contains 8 μL of 10 mg/mL). Std1–2 μL and std. 2–10 μL of standards mixture containing rutin (1 – Rf = 0.07), chlorogenic acid (2 – Rf = 0.18), isoquercitrin (3 – Rf = 0.26), hyperoside (4 – Rf = 0.41), hypericin (5 – Rf = 0.67), quercetin (6 – Rf = 0.86) and kaempferol (7 – Rf = 0.89), all at 100 μg/mL. Std3 - standard of rutin solution – 2 μL from 3.5 mg/mL
