Chemical constituents from the roots of Ranunculus ternatus.

Two new glycosides named as ternatoside A (1) and ternatoside B (2), with four known constituents sternbin (3), methylparaben (4), 4-O-D-glucopyranosyl-p-coumaric acid (5) and linocaffein (6) were isolated from the roots of Ranunculus ternatus, The structures of new compounds were determined by 1D and 2D NMR, MS techniques, and chemical methods.
