摘要
黄酮是枇杷花主要功效成分之一,具有显著的消炎止咳作用。本试验从国家果树种质福州枇杷圃中筛选国内外代表性枇杷种质55份,分析评价了其花中黄酮含量的差异及分级指标。研究结果显示,不同枇杷种质之间黄酮含量差异明显,分布范围为0.44%-2.28%,最高的卓南1号是最低者香钟25号的5.18倍;来源于福建的枇杷种质与浙江的存在极显著差异（P〈0.01）,与贵州、广西的存在显著差异（P〈0.05）;初步筛选出超高黄酮含量枇杷优异种质1份,初步建立了枇杷花黄酮分级指标,为今后枇杷花研究和利用奠定基础。
Flavonoids,as one of the important functional components in loquat flower,play a significant role in anti-inflammation and relieving cough. In this study,the flower flavonoid contents were analyzed in 55 accessions of loquat germplasm from National Fruit Fuzhou Loquat Gene-pool. The result showed that the flavonoid contents among the germplasm were significantly different,ranged from 0. 44% to 2. 28%. The highest content（Zhuonan No. 1） was 5. 18 times higher than the lowest one（Xiangzhong No. 25）. The average flavonoid level of loquat germplasm from Fujian province was significant difference with that from Zhejiang province（P 0. 01）,as well as Guizhou province and Guangxi Zhuang autonomous region（P 0. 05）. One loquat germplasm of ultra-high flavonoid content was screened out in this study,which is a promising material for further research. Meanwhile,the classification index for loquat flower flavonoid content level was established,which provides a basis for further exploitation of loquat flower.
