Cytotoxic steroidal glycosides from the rhizomes of Paris polyphylla var. yunnanensis

Phytochemistry, 2023
Paris polyphylla var. yunnanensis (Franch.) Hand.-Mazz. (Melanthiaceae), an important specie of the genus Paris, has long been in a traditional Chinese medicine (TCM) for a long time. This study aimed to isolate and identify the structures of bioactive saponins from the rhizomes of P. polyphylla var.

Steroidal saponins from Paris polyphylla var. yunnanensis

Phytochemistry, 2012
Eleven steroidal saponins, along with seven known steroidal saponins, were isolated from rhizomes of Paris polyphylla var. yunnanensis. Their chemical structures were elucidated on the basis of spectroscopic analyses and acid hydrolysis. Two of these compounds contained a spirostanol saponin aglycone, hitherto unknown in Nature.

Triterpenoid saponins from rhizomes of Paris polyphylla var. yunnanensis

Carbohydrate Research, 2013
Phytochemical investigation of the rhizomes of Paris polyphylla var. yunnanensis resulted in the isolation of six new oleanane-type triterpenoid saponins, paritrisides A-F (1-6), along with nine known triterpenoid saponins (7-15). The structures of the new compounds were elucidated on the basis of spectroscopic analysis and acid hydrolysis.

Complete genome sequence of Paris polyphylla chlorotic mottle virus infecting Paris polyphylla var. yunnanensis in southwest China

Archives of Virology, 2023
A novel virus infecting a Paris polyphylla var. yunnanensis plant, tentatively named "Paris polyphylla chlorotic mottle virus" (PpCMV), was discovered in the city of Lijiang, Yunnan Province, China. Its genome consists of 6384 nucleotides (nt), excluding the 3'-terminal poly(A) tail, and contains two open reading frames: ORF1 and ORF2.

Steroidal sapogenins from the aerial parts of Paris polyphylla var. yunnanensis and activity evaluation

Fitoterapia, 2023
Phytochemical investigation of an extract of the aerial parts of Paris polyphylla var. yunnanensis resulted in the identification of three new steroidal sapogenins, namely as paripolins A-C (1-3). With the aid of comprehensive spectroscopic techniques (NMR, IR, UV, MS), the structures of all isolated compounds were elucidated and subsequently screened ...
