Analysis of Flavonoids in Nothapodytes pittosporoides and Their Difference in Diferent Tissues
摘要
Abstract
To investigate the accumulation of flavonoids and explore their utilization value,widely-targeted metabolomics technology was employed to identify the metabolites in root,stem and leaf.Based on structural configuration classification,the accumulation status and differences of flavonoids were analyzed.The results showed that the numbers of flavonoids in leaf,stems and roots were 195,129 and 104,with 83 flavonoids common to both roots and stems,88 common to roots and leaves,and 114 common to stems and leaves,showing significant differences of 120,183 and 172,respectively,with 75 common to 3 tissues.The flavones and flavonols were the main components and contributors to flavonoid diversity and abundance,with their quantity and accumulation significantly increasing in stem and dramatically rising in leaf.The flavonoids in leaf of Nothapodytes pittosporoides was rich,containing 38 highly expressed components(abundance≥1.5×107)and 11 unique components,some of which had significant biological activity and pharmacological effects,indicating high potential for development and utilization.关键词
