Raw Polygonati Rhizoma (RPR) numbs the tongue and stings the throat, while prepared Polygonati Rhizoma (PPR) can remove the numbness of the tongue, and at the same time enhance its functions of invigorating the spleen, moistening the lungs and tonifying the kidneys. There are many active ingredients in Polygonati Rhizoma (PR), among which polysaccharide is one of the most important active ingredients. Therefore, we studied the effect of Polygonati Rhizoma polysaccharide (PRP) on the lifespan of Caenorhabditis elegans (C. elegans) and found that polysaccharide in PPR (PPRP) was more effective than Polysaccharide in RPR (RPRP) in prolonging the lifespan of C. elegans, reducing the accumulation of lipofuscin, and increasing the frequency of pharyngeal pumping and movement. The further mechanism study found that PRP can improve the anti-oxidative stress ability of C. elegans, reduce the accumulation of reactive oxygen species (ROS) in C. elegans, and improve the activity of antioxidant enzymes. The results of quantitative real-time PCR(q-PCR) experiments suggested that PRP may prolong the lifespan of C. elegans by down-regulating daf-2 and activating daf-16 and sod-3, and the transgenic nematode experiments were consistent with its results, so it was hypothesized that the mechanism of age delaying effect of PRP was related to daf-2, daf-16 and sod-3 of the insulin signaling pathway. In short, our research results provide a new idea for the application and development of PRP.<\/jats:p>","DOI":"10.3390\/molecules28052235","type":"journal-article","created":{"date-parts":[[2023,2,28]],"date-time":"2023-02-28T02:01:51Z","timestamp":1677549711000},"page":"2235","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":36,"title":["Polygonati Rhizoma Polysaccharide Prolongs Lifespan and Healthspan in Caenorhabditis elegans"],"prefix":"10.3390","volume":"28","author":[{"given":"Yage","family":"Luan","sequence":"first","affiliation":[{"name":"College of Chinese Medicine, Beijing University of Chinese Medicine, Beijing 102488, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu","family":"Jiang","sequence":"additional","affiliation":[{"name":"College of Chinese Medicine, Beijing University of Chinese Medicine, Beijing 102488, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rong","family":"Huang","sequence":"additional","affiliation":[{"name":"College of Chinese Medicine, Beijing University of Chinese Medicine, Beijing 102488, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xuan","family":"Wang","sequence":"additional","affiliation":[{"name":"College of Chinese Medicine, Beijing University of Chinese Medicine, Beijing 102488, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiujuan","family":"He","sequence":"additional","affiliation":[{"name":"College of Chinese Medicine, Beijing University of Chinese Medicine, Beijing 102488, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yonggang","family":"Liu","sequence":"additional","affiliation":[{"name":"College of Chinese Medicine, Beijing University of Chinese Medicine, Beijing 102488, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peng","family":"Tan","sequence":"additional","affiliation":[{"name":"College of Chinese Medicine, Beijing University of Chinese Medicine, Beijing 102488, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,2,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"R741","DOI":"10.1016\/j.cub.2012.07.024","article-title":"Ageing as a risk factor for disease","volume":"22","author":"Niccoli","year":"2012","journal-title":"Curr.
