Molecular networking-guided isolation of iridoids from Valeriana officinalis with anti-rheumatoid arthritis potential.
A feature-based molecular networking (FBMN)-guided strategy was applied to the targeted chemical investigation of the roots and rhizomes of Valeriana officinalis. This led to the isolation of sixteen iridoids (1-16), including three new compounds (1-3), along with one new monoterpene (17) and one new amide alkaloid (18...
