【 摘 要 】

Blumea was the resource for medicine such as l-borneol showing a great economic value. Interestingly, Blumea laciniata was widely used as a folk medicine in south of China and Asia. But the chemical compounds and specific pharmacological activity were rarely reported. Therefore, in this present work, the chemical components from B. laciniata were determined and the antioxidant ability on scavenging radicals and the protection on Hela cells against H2O2 were evaluated. The results showed the antioxidant ability was associated with the presence of polyphenols via response surface method. Additionally, chlorogenic acid, isoorientin, rutin, luteolin-4′-O-glucoside and cinnamic acid were firstly identified in B. laciniata. Moreover, the extract from B. laciniata (EBL) showed a strong antioxidant on clearing DPPH and ABTS free radicals with a lower EC50. Besides, EBL showed no toxicity on Hela cells and even could protect cells from H2O2 induced damage by sharply reducing the excessive reactive oxygen species, improving the mitochondrial membrane potential and then decreasing the generation of cell apoptosis. These outcomes could provide a promising understanding on the potential antioxidant.
