摘要
为探明不同品种枇杷叶中主要功能成分含量差异,给枇杷叶的加工利用提供理论参考,以生长在陕南安康的14个品种枇杷叶为材料,通过测定总黄酮、总酚、三萜酸、多糖、维生素C等主要成分含量以及ABTS阳离子自由基清除率和FRAP值指标,并运用主成分分析法对枇杷叶品质进行综合评价。结果表明:‘佳伶’、‘培优’和‘麦后黄’叶片中总黄酮、总酚和三萜酸含量较高,抗氧化活性较强,具有更好的药用价值和功能性。‘西农枇杷2号’和‘津云’叶片中多糖和维生素C含量较高,具有较好的营养价值。主成分分析评价结果,综合排名前三的品种依次为‘佳伶’、‘麦后黄’、‘培优’。
In order to explore the difference of main functional components in leaves of different varieties of loquat,theoretical reference was provided for the grafting utilization of loquat leaves.The leaves of 14 loquat cultivars growing in Ankang,southern Shaanxi Province were used as materials to evaluate the quality of loquat leaves by measuring the contents of total flavonoids,total phenols,triterpenoid acids,polysaccharides,vitamin C,ABTS cations free radical scavenging rate and FRAP value.The results showed that,the leaves of‘Jialing’,‘Peiyou’and‘Maihouhuang’had higher contents of total flavonoids,total phenols and triterpenoid acids,stronger antioxidant activity,and better medicinal value and function.The content of polysaccharide and vitamin C in the leaves of‘Xinong Loquat 2’and‘Jinyun’were higher,which had better nutritional value.The results of principal component analysis showed that the top three varieties were‘Jialing’,‘Maihouhuang’and‘Peiyou’.
