| description | <i>Polygonatum</i> rhizome is a traditional Chinese medicine of the same origin as food and medicine, and it has high economic value and social benefits. To screen the excellent germplasm resources of <i>Polygonatum kingianum</i> (<i>P. kingianum</i>) and clarify the nutritional and medicinal value of the rhizome of <i>P. kingianum</i>, we used widely targeted metabolomics to analyze the traits and metabolomics of rhizomes of different germplasms of <i>P. kingianum</i> from different growth years. The results showed that different germplasms and growth years of <i>P. kingianum</i> were rich in different nutritional and medicinal components. Among them, <i>Polygonatum kingianum</i> ‘Linyun 1′ rhizome (PWR) was richer in amino acids and derivatives, alkaloids, and phenolic acids, while <i>Polygonatum kingianum</i> rhizome (PRR) was richer in flavonoids, organic acids, and phenolic acids. Most of the differential compounds were mainly enriched in PRR when the growth year was one, and PWR had a greater variety and higher content of differential compounds in the third year, which also reflected the advantages of <i>Polygonatum kingianum</i> ‘Linyun 1′ (<i>P. kingianum</i> ‘Linyun 1′) as an excellent new variety of <i>P. kingianum</i>. The Kyoto Encyclopedia of Genes and Genomes (KEGG) metabolic pathway analysis showed that in <i>P. kingianum</i> with the same age and different germplasms, the significantly enriched metabolic pathway was more active in biosynthesis in PWR. In the same germplasm of <i>P. kingianum</i> from different years, the metabolites involved in PRR were mainly the highest in one-year-old <i>P. kingianum</i> (PR-1) or three-year-old <i>P. kingianum</i> (PR-3), and the metabolites involved in PWR were mainly the highest in three-year-old <i>P. kingianum</i> ‘Linyun 1′ (PW-3). The above results showed that the three-year-old PWR had more advantages based on chemical substances. Therefore, this study provided a new theoretical reference for the development of <i>P. kingianum</i> products and the breeding of new varieties. |
