FTIR spectra of O. stamineus ethanolic extract (OS-E), soybean phospholipids (SBP), and liposomes (OS-L). Remarkable changes can be seen in the infrared absorption spectra due to incorporation of OS extract in phospholipids; the broad band corresponding to OH groups is shifted from 3387 cm⁻¹ to 3421 cm⁻¹, the C = O bands at 1695 cm⁻¹ and 1607 cm⁻¹ disappeared, the band corresponding to C = O stretching in phospholipids is shifted from 1650 cm⁻¹ to 1634 cm⁻¹, the band at 1267 cm⁻¹ is shifted to 1225 cm⁻¹, the band at 1232 cm⁻¹ disappeared, and band at 1075 cm⁻¹ is shifted to 1071 cm⁻¹.
