Introduction

The Plant NGM 3 Pro(Next Generation Metabolomics) is purpose-built for plant metabolomics, providing high analytical accuracy and reliable solutions tailored to botanical research. Built on a proprietary in-house library of over 20,000 metabolite standards and powered by the Orbitrap Astral mass spectrometer, it integrates a stringent four-core algorithm framework, automated sample preprocessing and end-to-end quality control workflow to substantially enhance data precision and reproducibility. In addition, by leveraging the MetDNA3 metabolic network database, Plant NGM 3 Pro enables the discovery of previously undetected metabolic "dark matter", helping researchers uncover novel metabolites and potential metabolic pathways, thereby overcoming key bottlenecks in plant metabolism studies.

Title: Knowledge and data-driven two-layer networking for accurate metabolite annotation in untargeted metabolomics

Journal: Nature Communications

Impact Factor: 15.7

Background:

LC-MS-based untargeted metabolomics enables detection of both known and unknown metabolites in biological samples. However, reliable annotation of unknown metabolites remains as a central challenge in untargeted metabolomics.

Key Findings: Within MetDNA3, the authors developed a two-layer interactive network topology to enhance metabolite annotation. Recursive annotation achieved through cross-network interactions markedly improved identification efficiency, coverage and accuracy, providing strong technical support for research for metabolomics as well as broader life-science and biomedical applications.

Results: Across multiple biological sample datasets, MetDNA3 successfully annotated over 1,600 level 1 metabolites, and annotated more than 12,000 metabolites in total through using network-topology-based strategies. Building on this framework, the dual-network-driven propagation and iterative annotation approach enabled the discovery and validation of two previously unreported metabolites absent from existing human metabolome databases. The study further demonstrated that highly specific knowledge networks are critical for improving both annotation accuracy and propagation performance within network-based identification systems.
