沉香茶提取物的体外抗氧化和体内降血脂作用评价
Evaluation of the in vitro Antioxidant Activity and in vivo Blood Lipid-lowering Capability of Chenxiang Tea Extracts
摘要
Abstract
This experiment studied the chengxiang tea extracts from the raw materials of leaves of Aquilaria sinensis (Lout.) Gilg.Its radical scavenging activity,reducing power and metal chelating activity were determined to assays the in vitro antioxidant activity,and hyperlipidemia model mice were used to evaluate the blood lipid-reducing capacity of the water-extracts from Chenxiang tea.The results showed that the water extracts from Chenxiang tea have strong free radical scavenging activity,effective reducing power and chelating ability,with their IC50 values being of 700.45+38.04,58.03+4.4,16.24±2.4,70.69+2.8 and 215.46±14.27 mg/mL,respectively.The tea extracts can reduce the levels of TG and TC and increase the level of HDL-C in hyperlipidemia model mice serum.Compared with the model group,the differences were significant (P＜0.05).关键词
