Hypothesis
This study aims to determine the synthesis and regulatory mechanisms of secondary metabolites at different growth stages of Polygonatum odoratum.
Conclusion
The study reveals that flavonoids accumulate most in winter while steroidal saponins are highest in spring, providing insights for optimal extraction times.
Supporting Evidence
- 1,237 differentially abundant metabolites were identified.
- Flavonoids were most abundant in winter, while steroidal saponins peaked in spring.
- Proteins related to flavonoid and steroidal saponin biosynthesis were significantly expressed at different growth stages.
- Metabolomic and proteomic analyses provided insights into the regulatory mechanisms of secondary metabolites.
Takeaway
This study looks at how different parts of a plant change over time, showing when to pick it for the best medicine.
Methodology
The study used targeted metabolomics and proteomics to analyze changes in metabolite accumulation and protein expression in P. odoratum rhizomes at different growth stages.
