- W3146757323 abstract "【Objective】The scavenging effect of Siegesbeckia leaves extracts on hydroxyl free radical(·OH) was studied to provide references for its further development in medicinal aspect. 【Method】Siegesbeckia leaves extracts were obtained by refluxing in the water-bath. Using single factor and orthogonal test methods, the optimal extraction conditions of scavenging ratio of Siegesbeckia leaves extracts on hydroxyl free radical were determined. 【Result】The factors affecting the scavenging effect of the Siegesbeckia leaves extracts on hydroxyl free radical were found in the following order: material liquid ratio ethanol volume percentage water-bath temperature extraction time. Under the optimal extraction conditions of 1∶10.0 of material liquid ratio, 80% ethanol, and 2.0 hours at 60 ℃ refluxing temperature, the maximum capacity of scavenging effect to hydroxyl free radical was 91.7%. When Siegesbeckia leaves extracts were used as 1.0ml, the scavenging ratio to hydroxyl free radical was 92.6%. 【Conclusion 】Siegesbeckia leaves extracts have antioxidant effects,which shows that Siegesbeckia leaves extracts should be used as natural antioxidant resources for further study." @default.
