Anti-low density lipoprotein oxidation of the crude extract and different fractions of Terminalia chebuLa Retz
摘要
Abstract
The property of anti-low density lipoprotein oxidation of Terminalia chebuLa Retz(TCR) was studied in vitro Cu2+ induction on LDL.The effective fraction of TCR on the anti-LDL oxidation was determined by thiobarbituric acid reactive substance (TBARS) guided method.All these results were showed as follows:The inhibition rates of the TCR crude extracts on LDL oxidation were 64.31％,77.22％ and 82.66％,respectively.The ethyl acetate fraction possessed the most strong inhibition activity on LDL than other three fractions(p＜0.05),and was the effective fraction with the same concentrations.The inhibition rates of the effective fraction (0.5,0.9 and 2.7mg/mL) were 73.19％,81.85％ and 86.29％,respectively.The incubation periods of oxidation were delayed and degrees of oxidation were reduced by the effective fraction with different concentrations.The property of anti-low density lipoprotein oxidation of TCR was related to the total flavonoids and polyphenols in it.This study showed that TCR possessed strong anti-LDL oxidation activity and lay the foundation for further exploration on anti-atherosclerotic functional foods.关键词
