摘要

本研究测定了越南顺化省不同类型荷花茶（Nelumbo nucifera Gaernt.）的抗氧化和抗菌活性。结果表明，在四种荷花茶中，过氧化氢酶活性为 0.92-1.35 U/mg 蛋白，过氧化物酶活性为 0.97-2.67 U/mg 蛋白，抗坏血酸含量为 0.088-0.135% ，IC50 值为 4.98-6.03 mg/mL，四种荷花茶对细菌都有不同程度的抑制作用，敏感性较低。抑菌区的平均直径从 0.23 厘米增至 0.77 厘米。在大多数研究标准中，荷花茶的结果最高，荷叶茶的结果最低。从研究结果来看，越南顺化省种植的莲花茶具有很高的抗氧化和抗菌潜力。

Antioxidant and Antibacterial activity of Lotus tea in Thua Thien Hue province from Vietnam

In this study, we determined the antioxidant and antibacterial activity in different types of lotus tea (Nelumbo nucifera Gaernt.) in Thua Thien Hue province, Vietnam. The results showed that in four types of lotus tea, the catalase enzyme activity was 0.92-1.35 U/mg protein, the peroxidase enzyme activity was 0.97-2.67 U/mg protein, ascorbic acid content was 0.088-0.135%, the IC50 value was 4.98-6.03 mg/mL and all four kinds of lotus tea inhibited bacteria to a variable extent with low sensitivity. The inhibition zone’s mean diameter increased from 0.23 cm to 0.77 cm. The flower lotus tea gave the highest results on most of the research criteria and the lowest was lotus rhizome tea. From obtained results, tea produced from lotus plants grown in Thua Thien Hue province, Vietnam has a high potential for antioxidant and antibacterial properties.
