摘　　要：为了解紫肉甘薯中花青苷的组分构成及多样性分布,以来自国内外多家培育单位的68份紫肉甘薯品种资源为试验材料,利用液质联用技术测定了6类共计68种花青苷的含量。结果表明,6类花青苷中,矢车菊类和芍药类花青苷的含量较高,分布范围较广,天竺葵类花青苷的含量整体最低,分布范围最狭窄。相关性分析结果表明,检测到花青苷的总含量和矢车菊类、芍药类及矮牵牛类花青苷的含量均呈极显著正相关。系统聚类分析结果表明,68份紫肉甘薯品种资源被聚为6个类群,其中第Ⅱ类群6类花青苷的含量均较高,第IV类群各类花青苷的含量均较低。68种花青苷在68份紫肉甘薯品种中的检出情况表明,有7种花青苷能够在全部的紫肉甘薯品种中检出,10种只能在少于50份的材料中检出。68种花青苷含量的相关性分析结果表明,每类花青苷中均有几种花青苷的含量相等或呈极显著正相关。本研究通过对紫肉甘薯品种资源花青苷组分构成及多样性的分析与评价,筛选出6类花青苷含量较高的紫肉甘薯品种3份,单类花青苷含量较高的品种7份,为优质甘薯的推广和后续优质品种的选育提供了材料基础。To understand the composition and diversity distribution of anthocyanins in purple-fleshed sweetpotato,68 domestic and exotic purple-fleshed sweetpotato accessions were subjected for analyzing the content of 68 anthocyanins in 6 categories using LC-MS.The results showed that in six categories of anthocyanins,cyanidin and peonidin had higher content and wider distribution ranges,while pelargonidin had the lowest content and the narrowest overall distribution range.The significant positive correlation was detected between the total content of anthocyanins with the content of cyanidin,peonidin and petunidin,respectively.Systematic cluster analysis showed that the 68 purple-fleshed sweetpotato accessions were clustered into 6 groups,among which the content of all 6 categories of anthocyanins were higher in group II and lower in group IV.Seven anthocyanins were detected in all purple-fleshed sweetpotato varieties,whereas ten were detected in less than 50 varieties,respectively.Correlation analysis of the 68 anthocyanins showed that several anthocyanins in each category had equal content or showed highly significant positive correlation.Collectively,this study evaluated the composition and diversity distribution of anthocyanins composition of purple-fleshed sweetpotato accessions,and identified three purple-fleshed sweetpotato varieties with high content of 6 categories of anthocyanins and 7 varieties with high content of single type of anthocyanin.These materials are valuable for the promotion of highquality sweetpotato and the subsequent selection and breeding of high-quality varieties.
