枇杷花茶水提物的镇咳、抗炎与抗氧化作用研究
Study on Antitussive, Anti-inflammatory and Antioxidant Effects of Aqueous Extracts of Loquat Flower Tea
摘要
Abstract
The antitussive, anti-inflammatory and antioxidant function of loquat flower tea were studied by the methods of cough of mice stimulated by ammonia, xylene-induced ear acute inflammatory and scavenging capability of superoxide anion free radical and hydroxyl free radical, total antioxidant capability. The results showed that both high dose group (3000 mg·kg-1) and low dose group (700 mg·kg-1) of loquat flower tea had antitussive and anti-inflammatory effect, with high doses more effective. All concentrations of water extract showed certain reduction capacities, and had scavenging effects on hydroxyl free radical and superoxide anion. The water extract (20 mg·mL-1) had the best effect (absorbance value 0.903), better than 0.2 mg·mL-1 VC (absorbance value 0.814). The scavenging rate to superoxide anion of the 10 mg·mL -1 water extract was 47.32%, and the scavenging effect on hydroxyl radical of 20 mg·mL-1 water extract was obvious, which was 91.62%. The water extract of loquat tea had strong antitussive and anti-inflammatory, antioxidant effect.关键词
