摘要以向日葵花盘为原料，研究其乙醇提取物的不同溶剂萃取物中总酚、总黄酮含量及各萃取物的抗氧化、抑菌活性。以DPPH、ABTS自由基清除能力和总还原力为指标评价各萃取物抗氧化活性，分析总酚、总黄酮含量与抗氧化活性相关性；通过测定抑菌圈直径、最低抑菌浓度及最低致死浓度研究其抑菌活性。结果发现：乙酸乙酯萃取物中总酚、总黄酮含量最高，分别为9.04±0.92mg/g和4.30±0.021mg/g；不同溶剂萃取物均具有一定抗氧化活性及抑菌活性，乙酸乙酯萃取物抗氧化活性及抑菌活性最好，向日葵花盘提取物不同萃取物中总酚、总黄酮含量与DPPH、ABTS自由基清除能力和总还原力极显著相关（P<0.01），研究结果可为向日葵花盘开发利用提供实践基础。

Abstract: Using sunflower heads as raw material, this study investigated the total phenolic and total flavonoid contents in different solvent extracts of ethanol extracts, along with the antioxidant and antibacterial activities of each extract. Antioxidant activity was evaluated using DPPH and ABTS radical scavenging capacities and total reducing power as indicators, while the correlation between total phenolic and flavonoid contents and antioxidant activity was analyzed. The results showed that: Antibacterial activity was studied by measuring inhibition zone diameter, minimum inhibitory concentration (MIC), and minimum lethal concentration (MBC). The ethyl acetate extract exhibited the highest total phenolic and flavonoid contents at 9.04±0.92 mg/g and 4.30±0.021 mg/g, respectively. All solvent extracts demonstrated antioxidant and antibacterial activity, with the ethyl acetate extract exhibiting the strongest antioxidant and antibacterial effects. Total phenolic and flavonoid content in different sunflower head extracts showed extremely significant correlations (P<0.01) with DPPH and ABTS radical scavenging capacities and total reducing power. These findings provide a practical foundation for the development and utilization of sunflower heads.
