HPLC chromatograms of OS ethanolic extract in formulated and non-formulated forms. The chromatograms show presence of RA, TMF, EUP and SIN; the solubility of these compounds are improved significantly in the formulated OS extract compared to non-formulated extract. OS-E refers to O. stamineus extract, and OS-L refers to O. stamineus liposomes. RA, TMF, SIN and EUP refer to rosmarinic acid, 3′-hydroxy-5, 6, 7, 4′-tetramethoxyflavone, sinensetin and eupatorin, respectively.
