This study was designed to examine the total phenolic and flavonoid contents, radical scavenging and antibacterial activity of the ethanolic extracts from leaves, berries and stems of Hedera pastuchovii Woron. ex Grossh. The berry extract, which contained the highest phenolic and flavonoid compounds, showed an appreciable DPPH(·) scavenging ability in comparison with leaf and stem extracts. The various extracts exhibited moderate to good activity against both Gram-negative and Gram-positive bacteria, and the effectiveness of leaf extract was higher for all tested bacteria.
本研究旨在检测常春藤（Hedera pastuchovii Woron. ex Grossh.）叶、浆果和茎乙醇提取物中的总酚和黄酮含量、自由基清除能力及抗菌活性。浆果提取物中酚类和黄酮类化合物含量最高，与叶和茎提取物相比，其对1,1-二苯基-2-三硝基苯肼（DPPH(·)）具有显著的清除能力。各种提取物对革兰氏阴性菌和革兰氏阳性菌均表现出中度至良好的活性，且叶提取物对所有测试细菌的抗菌效果更佳。
