摘要
研究了薰衣草花茶水提物在体外对DPPH.、OH.、O2-.的清除和抑制亚油酸过氧化作用。并比较了不同浸提温度(50、60、70、80、90℃)对薰衣草花茶水提物抗氧化活性的影响。结果表明:薰衣草花茶水提物具有良好的抗氧化活性,浸提温度越高,水提物清除O2-.作用越强;水提物清除DPPH.、OH.最佳浸提温度是60℃;水提物抑制亚油酸过氧化作用的最佳浸提温度70℃。
The antioxidant activities of water extracts from Lavender tea were evaluated by study of scavenging capacity for DPPH· .OH· .O2· and restraining antioxidants for the linoleic acid . To investigate the effect of extraction temperature （50,60,70,80,90℃ ） on the antioxidant activities . The result indicated that water extracts of lavender tea had strong antioxidative activity. Water extracts were all strong scavenging capacity for DPPH· , OH· and restraining antioxidants of the linoleic acid at 60,60,70℃ of extraction temperature , respectively. The capacity of scavenging O2· of Water extracts （70 ℃） was better at high tempterature.
