Two New Highly Oxygenated Spirostanol Saponins from Paris polyphylla var. stenophylla.

ABSTRACT: Phytochemical investigation of the rhizomes of Paris polyphylla var. stenophylla led to the isolation of two new highly oxygenated spirostanol saponins, named paristenosides A (1) and B (2), together with seven known compounds. Their structures were established mainly on the base of NMR spectroscopic techniques and mass spectrometry, as well as chemical methods. In addition, the cytotoxicity of the two new saponins was tested. Two new highly oxygenated spirostanol saponins, paristenosides A (1) and B (2), were isolated from the rhizomes of Paris polyphylla var. stenophylla. Their structures were established mainly based on NMR spectroscopic techniques and mass spectrometry, as well as chemical methods.

Project description:The root of Paris polyphylla var. yunnanensis, a famous and endangered traditional Chinese herb, has a significant medicinal value. The aim of this study was to analyze the composition and functional characteristics of bacterial endophytes in roots, stems, and leaves of P. polyphylla var. yunnanensis. The 16S rRNA gene sequencing and functional prediction of bacterial endophytes in roots, stems, and leaves of P. polyphylla var. yunnanensis were conducted. The Chao and Shannon indices of the bacteria in roots were significantly higher than those in stems and leaves. The dominant endophyte phyla were Cyanobacteria, Proteobacteria, Bacteroidetes, Firmicutes, and Actinobacteria. The main genera detected in roots were unclassified Cyanobacteria, Rhizobium, Flavobacterium, and Sphingobium; the main genera in stems were norank_c__Cyanobacteria, Bacillus, and Pseudomonas; the main genera in leaves were norank_c__Cyanobacteria and Rhizobium. The microbiota in roots was particularly enriched in functional categories "extracellular structures" and "cytoskeleton" compared with stems and leaves (p < 0.05). Our study reveals the structural and functional characteristics of the endophytic bacteria in roots, stems, and leaves of P. polyphylla var. yunnanensis, which aids in the scientific understanding of this plant.The root of Paris polyphylla var. yunnanensis, a famous and endangered traditional Chinese herb, has a significant medicinal value.
