Ormosia henryi is an important and precious plant which is applied to aspects of medicine,wood and landscape garden.In order to further explore the volatile metabolites composition and the differences among different parts of O. henryi,a broad targeted metabolomics technique was used to identify and analyze the differences of metabolic components and highly enriched components in roots,branches and leaves.The results showed that 589 volatile metabolites were identified and annotated in roots,branches and leaves,which were divided into 16 classes of compounds,such as terpenoids,esters,heterocyclic compounds and hydrocarbons.Differential metabolites are significantly enriched in sesquiterpene and triterpene biosynthetic pathways.The results of cluster heat map showed that the concentration of most metabolites in branches and leaves was relatively high.Terpene compounds were down-regulated in roots,enriched in branches and leaves,and had high content in leaves.Terpene compounds such as limonene,β-ionone,α-pinene and α-terpinol were up-regulated and had important bioactive compounds with high utilization value.The analysis of volatile metabolites from different parts of O.henryi provided data support for further exploration of the medicinal characteristics of different parts and development and utilization.
