Tóm tắt

- A density functional theory (DFT) study on the hydroxyl radical scavenging properties of Kinsenoside originated from Anoectochilus roxburghii is presented. Two mechanisms, single electron transfer (SET) and hydrogen atom transfer (HAT) are considered. The thermochemical results demonstrate that the SET mechanism is not plausible to occur. With respect to the HAT, the interaction of OH• radical with Kinsenoside is also studied in detail by establishing potential energy surface (PES). This result strongly confirms that the C8H bond decides the radical scavenging activity of Kinsenoside with activation Gibbs free energy (∆G≠) and rate constants (k) of 1.1 kcal/mol and 5.9×10-8 cm3/molecules, respectively
