Steroidal saponins from the rhizome of Paris polyphylla and their cytotoxic activities.
TLDR
The results showed that the spirostanol framework of the aglycone and the terminal alpha-L-rhamnopyranosyl with 1-->2 linkage to the sugar chain of saponins at C-3 are essential for their high cytotoxicity, whereas the hydroxy group substitution atC-12 or C-17 of the Aglycone causes a reduction in their activity.

Quantitative and Qualitative Analysis of Flavonoids and Phenolic Acids in Snow Chrysanthemum (Coreopsis tinctoria Nutt.) by HPLC-DAD and UPLC-ESI-QTOF-MS
TLDR
The results showed total contents of the eight compounds in the samples with seed provenance from Keliyang (Xinjiang, China), are higher than in samples from the other five provenances, which demonstrated that provenance has a great influence on the constituents in snow chrysanthemum.
