Steroidal saponins with cytotoxic activity from the rhizomes of Paris polyphylla var. yunnanensis

Phytochemistry Letters, 2015
Two previously unreported spirostanol saponins, dianchonglouosides A and B (1 and 2), along with 7 known steroidal saponins (3-9) were isolated from the rhizomes of Paris polyphylla var. yunnanensis. Their structures were elucidated by extensive spectroscopic analysis (MS, 1D, and 2D NMR), and chemical methods.

C22-steroidal lactone glycosides from stems and leaves of Paris polyphylla var. yunnanensis

Fitoterapia, 2013
Further phytochemical investigation on the stems and leaves of Paris polyphylla var. yunnanensis has led to the isolation of three C(22)-steroidal lactone glycosides. Two of these are new compounds, designated as chonglouoside SL-7 (1) and chonglouoside SL-8 (2). Their structures were elucidated on the basis of extensive spectroscopic analysis, as well

[Determination of trace elements in Paris polyphylla var. Yunnanensis by ICP-AES].

Guang pu xue yu guang pu fen xi = Guang pu, 2014
Determination of metal elements in Paris polyphylla var. yunnanensis was studied by ICP-AES after HNO3-H2O2 digestion. The average recovery of the method for K, Mg and trace elements such as Cu, Fe, Cr, Zn, Mn and Pb in the Paris polyphylla var. yunnanensis was found to be 93.7%-108.2%, while RSD (n = 5) was 0.7%-4.6% for the metal elements. The method
